Join CHAPTR’s Global Network of Educators

You know what it takes to teach IB well. Rigor. Clear thinking. The ability to help students navigate ambiguity without doing the thinking for them. And maybe most importantly, you know you can't do it alone.

CHAPTR is built by educators, for educators. This isn't a job board where you compete on price. It's a network of IB teachers and exceptional alumni tutors who tutor one-on-one with students from leading schools across the U.S. and internationally.

For IB Teachers

If you teach at an IB school, you bring something invaluable: you know how the course actually works. You understand where students get stuck (Criterion D in Biology? The IA in Physics?). You've marked hundreds of papers and know what excellence looks like.

Tutor one-on-one in:

All IB languages (Literature, Language and Literature, Language B, Classical Languages)

Sciences (Biology, Chemistry, Physics, Environmental Systems and Societies)

Mathematics and Computer Science

Humanities (History, Geography, Economics, Psychology)

The Arts and Electives

Tutor during the school year when you know the curriculum intimately. Work with students preparing for finals, redoing assessments, or strengthening foundations.

Why Teachers Choose CHAPTR

Teaching, not administration. We handle payments, scheduling coordination, student matching, and all the backend logistics. You focus on teaching.

A community of your peers. Work alongside other IB teachers who understand the specifics of what you teach: the criteria, the assessment structures, the real gaps students face. Collaborate on approaches, share resources, learn from specialists in subjects outside your classroom expertise.

IB students, not random tutees. Every student on our platform comes from a rigorous IB program. You're not explaining algebra to unmotivated teenagers. You're deepening understanding with students who already know how to work.

Integrity built in. We're explicit about academic honesty and student ownership. Every tutoring relationship supports student agency and work that's genuinely theirs.

Flexibility on your terms. Work the hours that fit your teaching schedule, your school's calendar, your life. No pressure to fill slots. Work as much or as little as you want.

For IB Alumni: Homework Support

We also work with a small group of IB Diploma graduates who are now studying at top universities. Our alumni tutors help students with day-to-day homework: working through this week’s assignment, revisiting a concept from class, and building steady study habits. You remember what confused you during the IB and how you worked your way through it. That makes you a patient and credible guide for a student who is stuck on tonight’s problem set.

Internal Assessments, the Extended Essay, exam preparation, and HL content are led by our certified teachers. As an alumni tutor, you work alongside them, guiding students through their own work so the thinking stays theirs.

WHAT WE LOOK FOR

You know how much the IB asks of students, and you want to help them become more independent, not more reliant on you.
