Many Kenyan families are weighing the same decision: whether to move a child from the Competency-Based Curriculum (CBC) to a Cambridge or Pearson Edexcel IGCSE school. Switching from CBC to IGCSE is very doable, but the three questions that decide whether it goes smoothly are practical ones: which year your child will join, which subjects they take, and how quickly they close the gaps. This guide answers all three with what schools in Nairobi actually publish.

Demand is real. Semafor counted at least 60 international schools in Kenya and linked their growth to a substantial middle class and to parent concerns that followed the 2019 CBC rollout (Semafor, September 2025). In July 2026 The Standard reported that a growing number of private schools are adding international curricula alongside the CBC as parents look for globally recognised pathways (The Standard, July 2026).

How the CBC and British year groups line up

Kenya’s CBC follows a 2-6-3-3 structure (KICD FAQ). After two years of pre-primary and six years of primary, learners spend three years in Junior School (Grades 7, 8 and 9, roughly ages 12 to 14) and three in Senior School (Grades 10 to 12, roughly ages 15 to 17) (Business Daily). The first CBC cohort sat the Kenya Junior School Education Assessment (KJSEA) in late 2025, with 1,130,669 Grade 9 candidates, and entered Grade 10 from 12 January 2026 (The Star, December 2025).

The British year system that IGCSE schools use runs by age: Year 9 is ages 13 to 14, Year 10 is 14 to 15 and Year 11 is 15 to 16 (GOV.UK). IGCSE itself is usually a two-year course in Years 10 and 11, with a pre-IGCSE year in Year 9 (Brookhouse School).

CBC level (Kenya)	Approximate age	Closest British year by age	What that year means for IGCSE
Grade 7 (Junior School)	12–13	Year 8	Lower secondary, no IGCSE content yet
Grade 8 (Junior School)	13–14	Year 9	Pre-IGCSE foundation year
Grade 9 (Junior School)	14–15	Year 10	First year of the IGCSE course
Grade 10 (Senior School)	15–16	Year 11	IGCSE exam year, too late to start

Treat the table as a starting point. Ages overlap because Kenyan schools run January to December and British-curriculum schools run from August or September, and every school makes its own placement decision.

Which year will your child actually join?

Schools place by age first, then adjust after looking at reports and an assessment. Three published examples from Nairobi show the range:

• Brookhouse School says many of its High School students come from the Kenyan system and that “typically, new High School students will enter Year 9”, with admission decided case by case. It also notes that because its year starts in August, learners who join from a January-to-December school will have missed a term, and its teachers help them catch up (Brookhouse School).
• Braeside School Lavington (Braeburn group) describes itself as non-selective, runs rolling admissions and uses “admission testing if appropriate” to confirm a child can access the curriculum (Braeside Lavington admissions).
• Nova Pioneer Tatu City International takes applications from Early Years 2 to Year 9 and schedules a school tour and assessment once an application is in (Nova Pioneer).

In practice this gives three common outcomes:

1. Leaving after Grade 8: your child usually joins Year 9 and gets a full foundation year before IGCSE starts. This is the gentlest switch.
2. Leaving after Grade 9: your child is age-matched to Year 10. Schools may place them straight into the IGCSE course if English and maths are secure, or start them in Year 9 if there are gaps. A year “lost” on paper often produces better grades.
3. Leaving during Grade 10: your child is in CBC Senior School and age-matched to Year 11, the exam year. Joining Year 10 is the realistic option, because two years of content cannot be squeezed into one.

Ask the admissions office three direct questions: which year they propose, what the entrance assessment covers, and what support they give to learners who arrive mid-year.

IGCSE subject choices for a learner coming from CBC

CBC Senior School learners study seven subjects: four compulsory (English, Kiswahili or Kenyan Sign Language, Community Service Learning and Mathematics) and three optional subjects chosen mainly from one pathway: STEM, Social Sciences, or Arts and Sports Science (The Star, December 2025). IGCSE works differently. Each subject is a separate qualification, and the school builds a timetable around a core.

At Brookhouse, for example, IGCSE students take a core of English, Maths, Science and a modern foreign language alongside optional subjects, and Kiswahili is one of the languages offered (Brookhouse School). A sensible plan for a CBC learner looks like this:

• English: the subject that affects every other paper. Ask whether the school enters students for First Language English or English as a Second Language and why.
• Mathematics: Cambridge IGCSE Mathematics (0580) is tiered so students of different abilities can sit the right level (Cambridge International). Find out which tier (Core or Extended) your child is being prepared for and why.
• Sciences: CBC STEM learners can usually manage separate or combined sciences. Learners from the Social Sciences or Arts pathway should be honest about how much science they have done since Grade 9.
• Options that match the old pathway: a STEM learner might add computer science or additional maths; a Social Sciences learner might choose history, geography, business or economics.

Count your subjects. If your child might ever need their IGCSE results recognised for a Kenyan college or university, KNEC equates foreign certificates and expects the mandatory subject mix it uses itself: five subjects plus a language and mathematics, seven in total (Kenyans.co.ke, April 2025). Seven IGCSEs including English and maths keeps that door open.

Where CBC learners usually need to catch up

The CBC was designed around formative and continuous assessment rather than one-off examinations (KICD FAQ), while IGCSE grades depend mostly on timed written papers marked against a mark scheme. The content gap varies by child, but the skills gap is predictable:

• Extended writing under time pressure. IGCSE English and humanities papers reward structured answers written in a fixed time.
• Command words. “Describe”, “explain” and “evaluate” earn different marks. Learners new to the system often describe when the question asks them to explain.
• Algebra fluency. Rearranging formulae, simultaneous equations and quadratics appear across maths and the sciences.
• Exam stamina. An IGCSE exam season packs several long written papers into a few weeks, and learners need practice sitting full papers in one go.

A 12-week catch-up plan

This plan suits the term before your child starts, or their first term in the new school.

Weeks	Focus	What to do each week
1–2	Diagnose	Ask the school for its Year 9 or Year 10 scheme of work. Do one short past paper in English and maths untimed, and list every topic that caused trouble.
3–6	Rebuild maths and English foundations	Three maths sessions a week on the weakest topics (algebra first). Two English sessions: one reading-comprehension task, one piece of writing of about 350 words, checked against the mark scheme.
7–9	Science and options	One topic per subject per week. Learn the definitions, then answer short questions using the command word in each question.
10–12	Exam habits	One timed section of a past paper per subject each week, then self-mark with the mark scheme and redo every question that lost marks.

Keep sessions short and frequent. Four 45-minute sessions a week beat one long weekend session, especially for a child who is also adjusting to a new school.

For timed practice, Tutopiya’s Cambridge 0500 and Edexcel 4EA1 English Language past papers are a good starting point, and the IGCSE October/November 2026 timetable for Kenya shows how papers are spread across a real exam season.

If an international school is out of reach

Fees are the biggest barrier. At Brookhouse, Year 10 tuition was KSh 940,000 per term on its 2025/26 schedule (Brookhouse fees), while Nova Pioneer Tatu City International lists Year 9 tuition at KES 720,000 a year for 2026/27 (Nova Pioneer fee schedule, May 2026). If those numbers rule a school out, IGCSEs can also be taken as a private candidate. Our guide to studying IGCSE in Kenya without international school fees walks through that route, and CBC vs IGCSE vs A Level in Kenya compares the three pathways side by side.

What catch-up support costs

Tutopiya does not teach the CBC. It covers Cambridge and Edexcel IGCSE and International A Level, which is where a switching learner needs help. The Learning Portal organises study notes, practice questions, quizzes, flashcards and past papers by syllabus code, and a large section is free.

Premium unlocks every subject for one price, charged in Singapore dollars: S$10 a month (about KES 1,000) or S$50 a year (about KES 5,100). These figures use about KES 101 to S$1, based on S$1 ≈ US$0.78 and US$1 ≈ KES 130 on 12 November 2026 (Currency Beacon). For comparison, one term of Year 10 tuition at Brookhouse costs more than 180 years of Premium.

Start free

• Explore Cambridge and Edexcel IGCSE subjects by syllabus code on the Tutopiya Learning Portal, which covers 15 curricula, 130 subjects and more than 8,600 subtopics.
• Sign up free and start with English and maths, the two subjects that shape every placement decision.
• Premium unlocks every subject for about KES 1,000 a month or about KES 5,100 a year.
• If your child needs one-to-one help in the first term, book a free trial lesson with an IGCSE tutor.

Placement rules and entrance assessments are set by each school, so always confirm the year group and subject plan with the admissions office before you commit.

Frequently asked questions

Which IGCSE year will my CBC child join? +

By age, a learner finishing CBC Grade 9 lines up with Year 10, the first year of the two-year IGCSE course. Schools still decide case by case after an assessment, and some start new arrivals a year lower: Brookhouse says new High School students from the Kenyan system typically enter Year 9.

Can a Grade 10 CBC learner move straight into IGCSE? +

Yes, but expect to join Year 10 rather than Year 11, because IGCSE is taught over two years and Year 11 is the exam year. A Grade 10 learner is also mid-way through the CBC Senior School pathway, so moving early in the year wastes the least time.

Do international schools in Nairobi test CBC learners before admission? +

Many do. Braeside Lavington describes itself as non-selective but uses admission testing where appropriate, and Nova Pioneer Tatu City International schedules an assessment after an application. Ask each school which subjects the test covers and how the result affects year placement.

How many IGCSE subjects should a learner switching from CBC take? +

Schools typically build a core of English, mathematics and science, plus options. If your child may later need their IGCSEs recognised in Kenya, KNEC's equation guidelines expect seven subjects including mathematics and a language, so plan for at least seven.

When is the best time to switch from CBC to IGCSE? +

The end of Grade 8 or Grade 9 is the cleanest point, because your child can join Year 9 or the start of Year 10 before IGCSE content builds up. Kenyan schools run January to December while British-curriculum schools usually start in August or September, so a mid-year move can mean a missed term that needs to be made up.

Does Tutopiya teach the CBC? +

No. Tutopiya's Learning Portal and tutors cover Cambridge and Edexcel IGCSE, International A Level and IB, not the Kenyan CBC or KCSE. That makes it useful for the catch-up stage once your child has committed to IGCSE.
