What Is the IB Diploma Programme?

The International Baccalaureate Diploma Programme (IB DP) is a two-year, internationally-recognised pre-university qualification taken by students typically between ages 16 and 19. It is one of two universally accepted routes into top-tier higher education globally — the other being A Levels — and it is offered at over 3,500 schools across 159 countries.

Where A Levels favour depth in three subjects, IB DP is built around breadth across six subjects plus a structured core. Every IB Diploma student studies one subject from each of six subject groups, completes the three core requirements — Theory of Knowledge, the Extended Essay, and Creativity, Activity, Service — and sits standardised external examinations across the two years.

The IB Diploma Programme is one of four IB programmes (alongside the Primary Years Programme for ages 3–12, the Middle Years Programme for ages 11–16, and the Career-related Programme). This guide focuses specifically on the Diploma Programme — the qualification taken in the final two years of secondary school that universities use for admissions decisions.

Universities everywhere — from Cambridge, Oxford, and the Russell Group to the US Ivy League, Singapore’s NUS / NTU, Hong Kong’s HKU / HKUST / CUHK, the Australian Group of Eight, and the leading universities of Switzerland, Canada, and Western Europe — treat the IB Diploma as an admission qualification on par with A Levels, with grade requirements published per course. The rest of this guide unpacks the structure, the choices, and the trade-offs in detail.

IB DP Structure: How the Two Years Work

The Diploma Programme runs over two years, usually corresponding to the final two years of secondary school:

• DP1 (Year 1 of the Diploma): All six subjects begin, the Extended Essay topic is chosen, Theory of Knowledge classes start, and the CAS portfolio opens.
• DP2 (Year 2 of the Diploma): Internal Assessments are finalised across all six subjects, the Extended Essay is submitted, the Theory of Knowledge essay and exhibition are completed, mock exams happen in January or February, and final external exams are sat in May (Northern Hemisphere schools) or November (Southern Hemisphere schools).

Every IB Diploma is built from three components: the six subjects, the Core, and external assessment.

The Six Subjects

Every Diploma student studies exactly six subjects — one chosen from each of six subject groups (with one structured swap rule that we’ll cover below). Three of the six subjects are studied at Higher Level (HL) and the remaining three at Standard Level (SL) — although some students take four HL and two SL.

• Higher Level (HL): 240 teaching hours over two years. Greater depth, more content, more sophisticated assessment. HL is the level universities scrutinise most closely for subject-specific entry — Engineering targets HL Maths and HL Physics; Medicine targets HL Chemistry and HL Biology.
• Standard Level (SL): 150 teaching hours over two years. Same skills, less content depth. SL keeps the breadth of the Diploma achievable without overwhelming the student.

This HL/SL split is the IB’s mechanism for balancing breadth (six subjects across distinct fields) with depth (three or four subjects at a level competitive with A Level for university admissions).

The Core: TOK, EE, CAS

Beyond the six subjects, every Diploma student completes three additional core requirements:

• Theory of Knowledge (TOK): A critical-thinking course about the nature of knowledge itself — how we know what we know, the limits of different ways of knowing, and how knowledge claims are constructed across disciplines. Assessed by a 1,600-word essay on a prescribed title plus a TOK Exhibition (three real-world objects connected to a TOK question).
• Extended Essay (EE): A 4,000-word independent research essay on a topic of the student’s choice within one of the IB subjects. The EE is the IB’s flagship preparation for university-level academic writing and is supervised by a school-assigned mentor.
• Creativity, Activity, Service (CAS): A two-year portfolio of self-directed projects and experiences in three strands — creativity (arts, performance), activity (sport, physical challenge), and service (volunteering, community work). CAS is not graded for points but is mandatory for the Diploma. Failure to complete CAS means no Diploma, regardless of academic results.

The Core matters enormously for university admissions to liberal-arts-style institutions (US Ivy League, US liberal arts colleges, UK universities for non-STEM degrees), where the Extended Essay especially functions as evidence of research capability. The Core also generates up to 3 bonus points that are added to the subject total — making the maximum possible Diploma score 45.

External Examination

Final external exams take place in the May (Northern Hemisphere) or November (Southern Hemisphere) series of DP2. Each subject typically has 2–3 written papers sat under standardised global conditions. Papers are marked centrally by IB examiners — not by the student’s own teachers.

In addition, every subject includes an Internal Assessment (IA) — typically worth 20% of the final subject grade — that is completed during the two years and assessed by the school teacher, then moderated by the IB. IAs vary by subject: a Biology IA is an individual scientific investigation; an English IA is an oral commentary; a Maths IA is an extended written exploration; an Economics IA is a 750-word commentary on three real-world articles.

The Six IB DP Subject Groups: A Practical Comparison

Group	Field	Common Subjects
Group 1	Studies in Language and Literature	English A Literature, English A Language & Literature, plus equivalents in many other languages
Group 2	Language Acquisition	English B (second-language English), Spanish, French, Mandarin, German, etc., plus Ab Initio (beginner) options
Group 3	Individuals and Societies	Economics, History, Geography, Business Management, Psychology, Global Politics, Philosophy, Environmental Systems and Societies, World Religions
Group 4	Sciences	Biology, Chemistry, Physics, Computer Science, Design Technology, Sports Exercise and Health Science, Environmental Systems and Societies
Group 5	Mathematics	Mathematics: Analysis and Approaches (AA) — HL or SL; Mathematics: Applications and Interpretation (AI) — HL or SL
Group 6	The Arts	Visual Arts, Music, Theatre, Film, Dance — OR a second subject from any of Groups 1–4 instead

A few practical notes:

• The Group 6 swap rule. Students can replace Group 6 with a second subject from Groups 1, 2, 3, or 4. This is how Diploma students aiming at Medicine, for example, take both Biology and Chemistry (instead of taking the Arts), or how Engineering candidates take both Physics and Computer Science.
• Maths is mandatory. Every Diploma student takes Mathematics in some form — choosing between Analysis and Approaches (AA, proof-led pure maths) or Applications and Interpretation (AI, modelling-led applied maths), each at HL or SL. We unpack this choice below.
• Language Acquisition is mandatory. Even students who are native English speakers take Group 2 — usually a second language at Standard Level (Spanish B, French B, Mandarin B). Schools where the student is already proficient in two languages enable the Bilingual Diploma (more on this below).
• Environmental Systems and Societies sits in both Group 3 and Group 4 and can satisfy either requirement (but not both at once).

The six-subject structure is the defining feature of the Diploma — it forces students to study a humanity, a science, a language, mathematics, and a literature subject simultaneously. That’s a feature, not a bug, but it’s also why IB DP suits generalists more than specialists.

Choosing IB DP Subjects

Subject choice is the most consequential decision an IB DP student makes. The right framework:

How Many HL and SL?

The standard load is three HL + three SL. Some students take four HL + two SL when:

• They have the academic capacity and are applying to highly competitive universities where multiple HL subjects strengthen the profile (Cambridge Engineering, Oxford PPE, Ivy League STEM).
• One of their target degrees explicitly requires four HL subjects (rare, but happens for specific programmes).

Taking three HL at 6/7 is universally better than taking four HL at 4/5. The Diploma rewards consistency, and over-loading on HL is the most common cause of grade slippage.

How to Choose HL Subjects

Work backwards from the target degree:

1. STEM at competitive universities (Cambridge, Imperial, MIT, ETH Zurich, NUS Engineering). Typically HL Maths AA + HL Physics + a third HL science or relevant subject.
2. Medicine (UK, Singapore NUS, Australia, Hong Kong, Swiss EMS route). Typically HL Chemistry + HL Biology + a third HL (often Maths AA HL or English).
3. Law, PPE, International Relations (Oxford PPE, LSE, Sciences Po, NUS Law). Typically HL English Literature + HL History + HL Economics — strong essay subjects.
4. Business, Finance, Economics (LSE, HSG St. Gallen, Bocconi, Wharton). Typically HL Maths AA or AI + HL Economics + HL English.
5. Architecture, Computer Science, Design. Typically HL Maths + HL Physics or Visual Arts + a third strategic subject.

The IB DP entry requirements for every major university are published openly — searching “[university] [degree] IB requirements” returns the relevant grade profile in seconds. Build the HL list from the published targets.

Maths AA vs Maths AI: The Single Most Important Choice

Since the 2019 syllabus reform, IB Mathematics is split into two distinct courses:

• Mathematics: Analysis and Approaches (AA) — proof-led, pure mathematics, calculus-heavy. Required by virtually every top-tier Engineering, Physics, Mathematics, Computer Science, and quantitative Economics programme worldwide.
• Mathematics: Applications and Interpretation (AI) — modelling-led, statistics-heavy, applied. Suitable for Business, Social Sciences, Architecture, less mathematical Economics, and degree pathways where applied modelling matters more than abstract proof.

Both are offered at HL and SL. For STEM at competitive universities, AA HL is the universal expectation. For Business / Social Sciences / Architecture, AI HL or AA SL is usually sufficient.

This choice is irreversible mid-Diploma — switching from AA HL to AI HL after DP1 starts is extremely difficult. Get it right at subject selection. Our IB DP Mathematics tutors hub explains the AA-vs-AI decision in more detail and matches you with subject-specific tutors.

The DP Core: TOK, EE, CAS Explained

The Core is what genuinely distinguishes the IB Diploma from A Levels. It is also the area where students most often under-prepare.

Theory of Knowledge (TOK)

TOK is the IB’s signature critical-thinking course. Students explore questions like: How is scientific knowledge different from historical knowledge? Can language ever be neutral? What counts as evidence in ethics? The course runs across both years of the Diploma and is assessed by:

• A 1,600-word TOK Essay on one of six prescribed titles released each year.
• A TOK Exhibition — three real-world objects connected to a TOK prompt, presented with a written commentary.

The TOK Essay and Exhibition combine to produce a grade A–E. That grade, combined with the Extended Essay grade, generates the TOK/EE bonus points matrix (up to 3 points, added to the subject total).

Extended Essay (EE)

The Extended Essay is a 4,000-word independent research paper on a topic of the student’s choosing, within one of the IB subjects (or in World Studies, a multidisciplinary option). It is supervised by a school-assigned mentor and graded A–E by the IB.

The EE is widely regarded as the most useful preparation in the entire IB Diploma for university-level academic work. It teaches structured research, hypothesis-driven argumentation, formal citation, and sustained writing — all skills that university tutors and admissions officers consistently single out as valuable. A strong EE (grade A or B) significantly strengthens applications to UK universities (Cambridge in particular), US Ivy League, and any liberal-arts-style admissions process.

Creativity, Activity, Service (CAS)

CAS is a two-year portfolio of self-directed projects in three strands:

• Creativity — arts, music, performance, creative writing.
• Activity — sport, physical challenge, hiking, dance.
• Service — volunteering, community involvement, structured social-impact projects.

CAS is not graded for points, but it is mandatory — students must complete the required hours and reflections to be awarded the Diploma. CAS is also the IB’s main mechanism for ensuring students develop outside the classroom, and the CAS portfolio frequently provides the material for university personal statements and interview answers.

The most common mistake students make with CAS is treating it as a last-minute box-ticking exercise. The best CAS portfolios — and the ones that genuinely strengthen university applications — are built around 1–2 substantive year-long projects rather than a long list of one-off activities.

The TOK / EE Bonus-Points Matrix

The TOK essay grade (A–E) and the EE grade (A–E) combine in a published matrix to produce up to 3 bonus points. The bonus points are added to the subject total (out of 42 from the six subjects) — making the maximum possible IB Diploma score 45.

The matrix is non-linear: getting an A in TOK and an A in EE produces 3 bonus points; getting E in either produces 0 (and in some combinations means failing the Diploma entirely). For students chasing 40+ totals for competitive university offers, the bonus points often matter more than the marginal difference between a 6 and a 7 on a single subject.

IB DP Grading Explained

Each of the six subjects is graded 1–7, where 7 is the highest. The grade boundary on each subject is set per exam session by the IB based on paper difficulty and cohort performance, so the exact percentage required for a 7 varies session to session.

Grade	Approximate Threshold	Description
7	~85%+ overall	Excellent — top university entry grade
6	~75%+	Very good — strong university grade
5	~65%+	Good — meets most university requirements
4	~55%+	Satisfactory
3	~45%+	Mediocre — below most university thresholds
2	~35%+	Poor
1	Below	Very poor — usually means failing the Diploma

The six subject grades (max 42 points) plus the TOK / EE bonus (max 3 points) sum to the Diploma total out of 45.

What the Diploma Totals Mean

Total	What It Means
45	Perfect score. Achieved by ~0.2% of candidates globally.
40+	Top decile. Profile for Cambridge, Oxford, Imperial, US Ivy League, NUS Medicine, Singapore Engineering.
38+	Strong. Profile for most Russell Group, Australian Group of Eight, top Canadian universities.
35+	Solid. Profile for many strong international universities and most second-tier UK / EU options.
30+	Passing. Diploma awarded; admission to less competitive universities and many continental EU programmes.
Below 24	Diploma not awarded.

Failing Conditions

The Diploma is NOT awarded if any of the following occur, regardless of total points:

• Total below 24 points.
• A grade of 1 in any subject (HL or SL).
• More than three grades at 3 or below.
• More than two grades at 2 or below at HL.
• Failure to complete the CAS requirement.
• A grade of E in either TOK or the Extended Essay.

These threshold rules matter — a student with 38 points who fails CAS gets no Diploma. Universities are aware of these conditions and will not accept a “Diploma Course Certificate” (the consolation prize for students who pass subjects but don’t complete the Diploma) in lieu of the full Diploma.

Assessment: IAs, External Exams, EE, TOK

IB DP assessment is unusually layered. Each subject has both external assessment (exams marked centrally by IB examiners) and internal assessment (typically a 20% weighting, marked by the school teacher and moderated by the IB). Understanding the weight of each is the difference between targeting a 7 and a 6.

Internal Assessment (IA)

The IA is the single biggest grade-lift opportunity in IB DP — and the area schools most often run out of time to coach properly. Examples:

• Sciences (Bio, Chem, Physics): An individual scientific investigation, ~10 pages, on a research question of the student’s choice. Worth 20% of the final grade. Marked on five criteria (Research Question, Analysis, Conclusion, Evaluation, Communication). The Evaluation criterion is what most often separates a 6 from a 7.
• Mathematics: A written exploration (mathematical investigation), 12–20 pages, on a topic of the student’s choice. Worth 20%.
• English A (Lang & Lit or Literature): Internal Oral — a 15-minute recorded commentary connecting one literary text and one non-literary text to a chosen global issue.
• History: A 2,200-word historical investigation, including reflection on the historian’s craft.
• Economics: Three commentaries (750 words each) on real-world news articles, applying course concepts.

Because the IA is school-assessed and moderated, the quality of school IA coaching varies enormously. One-to-one tutoring on the IA — particularly on the Evaluation criterion in the sciences and on the analysis section in Mathematics — is consistently the highest-leverage IB DP tutoring you can buy.

External Exams

May/November exams are 2–3 papers per subject (HL papers are longer and more demanding). Papers are typically sat over a 3-week window in the final term of DP2.

For sciences at HL, the external structure is usually: Paper 1 (multiple choice on the syllabus), Paper 2 (data-based + extended response on the syllabus), Paper 3 (data + Option topic). Schools generally pick the Option for the entire class.

TOK Essay + EE

Both are written components submitted in DP2 — the TOK Essay in the spring of DP2, the EE typically earlier in DP2. Both are marked externally by IB examiners and grade A–E.

IB DP University Acceptance and Pathways

The IB Diploma is universally accepted across English-medium higher education. Specific pathways:

United Kingdom

• UCAS applications. All UK universities accept IB DP via UCAS. Offers are made in IB total points + specific HL grades (e.g. “38 points including 666 at HL”).
• Russell Group. The 24 leading UK research universities (Cambridge, Oxford, Imperial, UCL, LSE, KCL, Warwick, Edinburgh, Manchester, etc.) typically ask for 36–40 points with specific HL grades, 38–42 for the most competitive programmes.
• Oxbridge. Cambridge Engineering: typically 40–42 with 776 HL incl. Maths AA + Physics. Oxford PPE: typically 39 with 766 HL incl. relevant subjects.
• Medicine (UK). Typically 38–40 points with 666–766 at HL incl. HL Chemistry + usually HL Biology + a third HL.

United States

US universities accept IB DP and frequently award advanced standing credit — HL subjects at grades 5/6/7 often translate to first-year university credit, accelerating the degree. The Ivy League, MIT, Stanford, Caltech, and the rest of the top tier value the IB’s breadth (six subjects + Core) as evidence of well-rounded academic readiness.

US admissions also factor SAT/ACT scores, the Common Application personal statement, extracurricular profile, recommendations, and (for some courses) supplemental essays alongside IB results.

Singapore

NUS, NTU, SMU, and SUTD accept IB DP with subject-specific grade requirements. NUS Engineering typically asks for IB 36+ with HL Maths AA + Physics; NUS Medicine asks for 40+ with HL Chemistry + Biology. Singapore admission is intensely competitive — the top quartile of applicants present 40+ totals.

Hong Kong

HKU, CUHK, HKUST, PolyU, and CityU admit international applicants via the non-JUPAS route, accepting IB DP directly. HKU MBBS (Medicine) typically asks for 40+ points with HL Chemistry + Biology; HKU Engineering / HKUST Engineering ask for 36+ with HL Maths + Physics.

Australia, Canada, Continental Europe, Switzerland

The Australian Group of Eight (Melbourne, Sydney, ANU, UNSW, Monash, UWA, Adelaide, Queensland), top Canadian universities (Toronto, McGill, UBC, Waterloo), and continental European universities (TU Delft, KU Leuven, Bocconi, Sciences Po, HEC Paris, TUM, EPFL Lausanne, ETH Zurich, HSG St. Gallen) all accept IB DP with course-specific grade requirements published on their international-admissions pages.

Swiss medical schools (Geneva, Lausanne, Zurich, Basel, Bern) admit on IB Diploma + the EMS aptitude test (Eignungstest für das Medizinstudium) for non-Swiss-Matura applicants — see our IB DP Chemistry tutors in Geneva and IB DP Biology tutors in Zurich for board-specific guidance.

IB DP vs A Levels: The Real Comparison

This is the most common question parents weigh. Here’s the clean breakdown:

	IB DP	A Levels
Breadth vs depth	6 subjects + Core	3 subjects (sometimes 4)
Languages	Two languages mandatory (Lang & Lit + Lang Acquisition)	None mandatory
Mathematics	Mandatory (AA or AI, HL or SL)	Optional
Practical / research component	Extended Essay (4,000 words), TOK Essay, Internal Assessments	Mostly exam-based; some practical endorsement / written practical papers per subject
Service / extracurricular	CAS portfolio mandatory	Not part of qualification
Grading scale	1–7 per subject, max 42 + 3 bonus = 45	A*–E per subject
Exam timing	Linear — all final exams in DP2 (May or November)	Linear on UK boards (end of Year 13); modular on Cambridge / Edexcel IAL (January + June)
Re-sit options	One full Diploma re-sit allowed	Per-unit re-sits on modular international boards; whole-subject re-sit on linear UK boards
University acceptance	Universal across English-medium HE	Universal across English-medium HE
Best for	Generalists; students who want breadth + research; US Ivy / liberal arts pathway	Specialists; students with clear single-subject focus; UK STEM / Medicine pathway

The single most important point: universities accept both equally. Cambridge admissions does not favour IB over A Levels; LSE does not favour A Levels over IB. The qualification standard is set at the level, not at the qualification name.

The choice depends on student fit. Specialists with a clear single-subject passion (a future engineer who already loves Maths and Physics) often thrive in A Levels — the depth of three subjects suits their inclination. Generalists who want to keep multiple disciplines open simultaneously (or who are aiming at the US Ivy League where breadth is valued) often thrive in IB DP.

For a more detailed comparison, our A Levels vs IB: Which is Better? guide unpacks the trade-off in depth.

IB DP vs IGCSE and IB MYP: How They Connect

A quick reference for parents weighing the pre-IB-DP qualifications:

• IGCSE / GCSE. The pre-A-Level qualification — taken at ages 14–16. IGCSE leads cleanly into IB DP for students transitioning from a British international school into an IB sixth form. There’s no mandatory pre-DP qualification; many IB DP students come from IGCSE, others from IB MYP, others from national curricula. For the broader picture, see our Complete IGCSE Syllabus Guide 2026.
• IB MYP. The Middle Years Programme runs from ages 11–16, the IB’s structured precursor to the Diploma. MYP develops research skills, the Personal Project (a precursor to the EE), and the IB Learner Profile. MYP students transition naturally into IB DP, but it is not required — many DP students come from non-MYP backgrounds.
• IB PYP / IB CP. The Primary Years Programme (ages 3–12) and the Career-related Programme (a vocational alternative to DP) are separate from this guide’s scope.

The Bilingual Diploma

The Bilingual Diploma is awarded to students who complete one of the following profiles:

• Two Group 1 subjects (Studies in Language and Literature) at grade 3 or above — for example, English A Literature + Spanish A Literature, or French A Language & Literature + Mandarin A Literature.
• A Group 3 or Group 4 subject completed in a language other than the language of instruction.
• The Extended Essay written in a Group 2 (Language Acquisition) language.

For multilingual families and students attending bilingual schools in Geneva, Zurich, Singapore, Hong Kong, Dubai, or Brussels, the Bilingual Diploma is a recognised distinction that strengthens international university applications, particularly in Europe and Asia.

Frequently Asked Questions

What’s the difference between IB DP and IB MYP?

The Diploma Programme (DP) is the IB’s pre-university qualification, taken at ages 16–19 in the final two years of secondary school, and used by universities for admissions decisions. The Middle Years Programme (MYP) is the IB’s middle-school programme, taken at ages 11–16. MYP is preparation for DP — it is not itself a pre-university qualification. Universities admit on the DP, not the MYP.

How many subjects do you take in IB DP?

Exactly six. One from each of the six subject groups (with the structured swap rule allowing a second Group 1–4 subject in place of Group 6 Arts). Three or four subjects are studied at Higher Level (HL); the remaining at Standard Level (SL).

What’s the maximum score on IB DP?

45 points. Six subject grades of 7 each (42 points) plus the maximum 3 bonus points from the TOK/EE matrix. A perfect 45 is achieved by approximately 0.2% of candidates globally each year.

Is IB DP harder than A Levels?

Different rather than harder. IB DP demands breadth across six subjects plus the Core (TOK, EE, CAS), which is a significant time and workload commitment. A Levels demand depth in three subjects with no equivalent breadth requirement. Most students find one or the other a better fit, but the qualification standards are equivalent — universities don’t treat one as “easier” than the other.

Should my child take Maths AA or Maths AI?

For STEM at competitive universities (Engineering, Physics, Maths, Computer Science, quantitative Economics at Cambridge, Imperial, MIT, ETH Zurich, NUS), Maths AA (especially AA HL) is the universal expectation. For Business, Social Sciences, Architecture, or non-quantitative degrees, Maths AI (HL or SL) is usually sufficient. The choice is essentially irreversible mid-Diploma, so it matters at subject-selection time.

What is the Extended Essay, and how important is it?

The Extended Essay is a 4,000-word independent research paper on a topic of the student’s choice within one of the IB subjects. It’s graded A–E and contributes (along with the TOK essay) up to 3 bonus points to the Diploma total. Strong EEs (A or B) significantly strengthen UK university applications (Cambridge in particular) and US Ivy League / liberal-arts applications by demonstrating university-ready research and writing capability.

Is CAS graded?

No — CAS is graded as completion or non-completion. There are no points awarded for CAS. However, CAS is mandatory for the Diploma — failing to complete the required CAS hours and reflections means the Diploma is not awarded, regardless of academic results.

Can students re-sit IB DP?

Yes — the IB allows one full Diploma re-sit in a subsequent exam session. Individual subjects within a re-sit can be improved or held; the better grade is used. Re-sits are most common for students aiming to improve from 36 to 38+ for a specific university offer.

What HL subjects do UK universities require?

This varies by degree. Cambridge Engineering typically asks for HL Maths AA + HL Physics. Cambridge Medicine asks for HL Chemistry + usually HL Biology + a third HL. Imperial Computing asks for HL Maths AA at 7. Oxford PPE asks for strong HL Maths or HL English + History. The published IB requirements for every UK degree are visible on each university’s international-admissions page — work backwards from the target degree.

Are IB DP scores accepted for US university admission?

Yes — every major US university accepts IB DP. Many award advanced standing credit for HL subjects at grades 5, 6, or 7 (allowing the student to skip introductory courses or accelerate the degree). For US admission, IB results sit alongside the Common Application personal statement, SAT or ACT, recommendations, and extracurricular profile.

How does the IB Diploma compare to APs?

APs (Advanced Placement) are individual subject exams typically taken alongside a US high-school diploma. The IB Diploma is a complete pre-university qualification on its own. UK universities prefer IB DP or A Levels over APs for international applicants. US universities accept IB DP as a strong international qualification and may also award credit for high HL grades comparable to AP credits.

What is the Bilingual Diploma?

The Bilingual Diploma is awarded when a student completes either two Group 1 subjects at grade 3+, a Group 3 or 4 subject in a non-instruction language, or the Extended Essay in a Group 2 (Language Acquisition) language. It is a recognised distinction valued by European and Asian universities.

Can my child do IB DP online?

IB DP is primarily a school-based qualification — the IB does not currently authorise full online-only Diploma delivery in the same way it authorises in-person schools. However, online tutoring (one-to-one subject support, IA coaching, EE supervision) is universally used by IB families. Pamoja Education runs online IB Diploma courses that some schools integrate as part of the official Diploma — typically for niche subjects schools cannot staff locally.

What’s the deadline for IB DP subject choice?

Subject choice is locked at the start of DP1 (the first year of the programme), typically in August or September of the academic year the student turns 16–17. Changing HL/SL or AA/AI mid-Diploma is extremely difficult; changing subjects is essentially not possible after the first few weeks of DP1. Subject selection in the spring/summer before DP1 starts is the high-leverage moment.

Resources & Next Steps

If you’re starting an IB DP programme — or your child is — the most useful next steps are:

• Get subject choice right based on the target degree. Work backwards from the published IB requirements for the target university programme.
• Decide Maths AA vs Maths AI early — this is the single most important irreversible choice in IB DP subject selection.
• Plan the Extended Essay topic by mid-DP1 — the strongest EEs come from genuine personal interest plus a well-defined research question, not last-minute topic-grabbing.
• Start CAS substantively in DP1 — 1–2 year-long substantive projects build much stronger CAS portfolios than a string of one-off activities.
• Use targeted tutoring on the IAs — IA coaching is consistently the highest-leverage IB DP tutoring you can buy. School class time often runs out before the IA Evaluation and Analysis sections are properly coached.
• Match tutors to subject + level (HL vs SL). Online IB DP tutoring is matched per subject and HL/SL — see our hubs: IB DP Mathematics, IB DP Physics, IB DP Chemistry, IB DP Biology, IB DP English Language, or the full IB DP hub.

For city-specific tutor matching, we cover the major IB hubs worldwide:

• IB DP tutors in Geneva — birthplace of the IB Diploma (Ecolint, 1968)
• IB DP tutors in Zurich — ZIS, ICS, SIS Swiss International School
• IB DP tutors in Auckland — AIC, Kristin, Diocesan, St Cuthbert’s
• IB DP tutors in Hong Kong — ESF, HKIS, CIS, German Swiss, Yew Chung
• IB DP tutors in Singapore — UWCSEA, SAS, Tanglin Trust, ISS
• IB DP tutors in Dubai — GEMS World Academy, Dwight, Repton, Nord Anglia

The two-year IB Diploma Programme is a significant commitment, but the rewards are real: IB graduates consistently report exceptional preparation for university research, writing, and independent study — and the Diploma opens admissions doors at every leading English-medium university worldwide.
