IB, the International Baccalaureate, is offered by a small number of Kolkata schools and structured very differently from Indian boards: the Diploma Programme requires six subject groups plus the Extended Essay, Theory of Knowledge, and CAS components, alongside internal assessments that count meaningfully toward the final grade. Tutors here need to understand IB's specific assessment criteria and command terms, which differ subject by subject and are graded against published rubrics rather than a fixed answer key.
Beyond subject content, many IB tutors also help with the Extended Essay, Internal Assessments, and Theory of Knowledge, all core IB Diploma requirements that do not exist in CBSE, ICSE or IGCSE.
Higher Level (HL) subjects go deeper and require more contact hours than Standard Level (SL) within the same subject. Students choose a mix of HL and SL subjects, so confirm with a tutor which level your child needs help with.
IB is offered by a smaller number of Kolkata schools compared to CBSE or ICSE, which is why finding a genuinely IB-experienced tutor, rather than one who has only taught Indian boards, is worth confirming directly before booking.
