When a student joins the IB Diploma late, tutoring helps most by quickly identifying missed content in HL subjects, especially maths and sciences, and by building the IB skills, such as markscheme-style answers and the core, that the class has already started. Late joiners are often moving country or switching from another curriculum. This guide explains how to plan a catch-up and where a tutor makes the biggest difference.

Written by Tutopiya, an online tutoring company that teaches IB Diploma subjects one-to-one.

Key takeaways

• Ask the coordinator what’s been covered and what’s coming.
• Prioritise maths and HL sciences.
• Don’t forget the core: TOK, CAS and the Extended Essay.
• Most students catch up within a term with focused help.

What does joining late involve?

Joining the IB Diploma late means starting DP1 after the class has begun, so the student must catch up on taught content, adapt to IB assessment styles and join the core components already under way. Schools decide whether late entry is possible. The IB Diploma Programme structure, six subjects plus the core, is the same for everyone.

Area	What may have been missed
HL subjects	Several weeks of content
Maths AA or AI	Foundational topics
TOK	Early lessons and concepts
CAS	Planning and early experiences
Extended Essay	Introductory sessions

Where do late joiners struggle?

Late joiners usually struggle most with missed topics that later lessons build on, and with IB-style command terms and markschemes that differ from their previous curriculum. Other problems:

• unfamiliar subject choices or levels;
• different approach to coursework;
• adjusting socially while catching up.

How to plan the catch-up: step by step

1. Ask each teacher what has been covered.
2. Compare with what your child studied before.
3. List missed topics by subject.
4. Prioritise maths and HL sciences.
5. Book a diagnostic trial lesson in the top priority.
6. Set a six- to ten-week catch-up plan.
7. Review progress with the school.

Which subjects first?

Priority	Why
Maths	Topics build on each other
HL sciences	Heavy content
A new language level	Placement may differ
Humanities	Usually easier to catch up

Coming from another curriculum

Students from IGCSE, A Level, American or national curricula often know much of the content but need to learn IB command terms, markscheme expectations and internal assessment styles. Our guide to tutoring when changing curriculum covers this in more detail.

Don’t forget the core

TOK, CAS and the Extended Essay are part of the Diploma, so late joiners should meet the coordinators early and plan how to catch up. A tutor can help with general TOK thinking skills, but CAS and the EE follow school processes.

What does a good catch-up lesson look like?

1. A short diagnostic on a missed topic.
2. Clear teaching with IB-style examples.
3. Practice using IB command terms.
4. Marking with markscheme expectations.
5. The next missed topic noted.

How to tell tutoring is working

• the student follows class lessons comfortably;
• test marks match classmates’;
• fewer gaps appear in new topics;
• confidence and engagement improve.

Signs the catch-up isn’t working yet

• still lost in class after four weeks;
• new gaps appearing as lessons move on;
• falling behind on core deadlines.

If you see these, review the plan with the tutor and teachers, and consider adding a second subject or more time temporarily.

How parents can help

• meet the coordinator early;
• keep routines stable during the move;
• give your child time to settle socially;
• celebrate milestones in the catch-up plan.

Questions to ask a tutor

1. Have you taught late IB joiners?
2. How will you find the missed topics?
3. How long do you expect the catch-up to take?

How much tutoring is enough?

One to two hours a week in priority subjects for six to ten weeks suits most late joiners, then reducing once they’re level with the class.

A sample six-week catch-up

Week	Focus
1	Diagnostics in maths and HL sciences
2–3	Missed maths topics
4–5	Missed science topics
6	IB-style questions and review with teachers

Settling in

Academic catch-up goes faster when students feel settled. Encourage clubs and activities, keep in touch with old friends and allow some time before expecting top results.
