IGCSE vs ICSE vs CBSE vs IB: comparing boards in India
Choosing a school board is one of the biggest decisions for families in India. Here are the four you will hear about most, compared side by side on the things that matter: who runs them, how they are examined and where they lead.

The four at a glance
- CBSE: the Central Board of Secondary Education, a national board. Students take board exams in Class 10 and Class 12, and schools widely use NCERT textbooks.
- ICSE and ISC: run by the Council for the Indian School Certificate Examinations (CISCE). ICSE is the Class 10 exam and ISC the Class 12 exam.
- Cambridge IGCSE: an international qualification from Cambridge International for roughly ages 14 to 16, usually followed by Cambridge AS and A Levels or the IB.
- IB: the International Baccalaureate. Its Diploma Programme covers the years equivalent to Classes 11 and 12.
How they are examined
- CBSE and ICSE/ISC: board exams at the end of Class 10 and Class 12, with marks usually expressed as percentages, plus internal assessment in many subjects.
- IGCSE: end-of-course exams in each subject, often with Core and Extended routes, graded A* to G (or 9 to 1 in some cases).
- IB Diploma: exams in May with internal assessments in every subject, graded 1 to 7 per subject and 45 points in total.
Maths and science
- CBSE maths and science follow NCERT, which many students also use for Indian entrance exam preparation.
- ICSE keeps science as separate physics, chemistry and biology in Classes 9 and 10.
- IGCSE Maths at Extended level and IGCSE Physics are designed to lead into A Level or IB study, with practical skills assessed in a dedicated paper.
- IB offers Maths AA or AI and Physics at SL or HL, with a strong emphasis on investigation and the internal assessment.
Where they lead
- Students aiming at Indian entrance exams such as JEE or NEET often prefer CBSE or ISC in Classes 11 and 12, because the exam syllabuses are closely aligned with NCERT content.
- Students aiming at universities abroad often choose IGCSE followed by A Levels or the IB, or the IB on its own.
- The Association of Indian Universities recognises Cambridge and IB qualifications for admission to Indian universities, but each university sets its own rules, so check them early.
A family deciding after Class 8
A student loves maths and physics and wants to study engineering, either in India or abroad. What are sensible routes?
- Mainly India (JEE): CBSE or ICSE to Class 10, then CBSE or ISC in Classes 11 and 12, alongside entrance exam preparation.
- Mainly abroad: IGCSE, then A Levels (Maths, Further Maths, Physics) or the IB Diploma with Maths AA HL and Physics HL.
- Keeping both open: decide by the end of Class 10, because Classes 11 and 12 are where the routes divide most.
Questions to ask a school
- Which board do you offer from Class 9, and from Class 11?
- For IGCSE: which subjects, and at Core or Extended?
- For IB: which HL subjects can be combined, and how is the IA supported?
- What did recent students go on to study, in India and abroad?
Switching boards
Many students change boards at the end of Class 10, for example from ICSE or IGCSE to CBSE for Classes 11 and 12, or from CBSE to the IB Diploma or Cambridge A Levels. Switching is common and workable, but plan for it:
- IGCSE to CBSE: expect NCERT-style questions and percentage marking, and use NCERT textbooks from the first week.
- CBSE or ICSE to IB: expect internal assessments, essays and the IB core, and practise writing longer answers.
- CBSE or ICSE to A Levels: expect fewer subjects in more depth, and Cambridge mark schemes that reward precise working.
Maths and physics for engineering abroad
For students heading to engineering abroad, what matters most is strong maths and physics in the last two years: Maths and Physics at A Level (often with Further Maths), Maths AA HL and Physics HL in the IB, or strong CBSE or ISC results plus AP Calculus BC and AP Physics C. Admission tests such as the ESAT or TMUA may also be required for some UK universities.
More questions
Which board is best for studying abroad?
IGCSE followed by A Levels or the IB is the most common route for students applying abroad, but strong CBSE or ISC students also apply successfully, often adding SAT or AP scores.
Which board has the most schools in India?
CBSE is the largest by number of affiliated schools. ICSE, Cambridge and IB schools are fewer, and are more common in big cities.
Common mistakes
- Choosing a board only by reputation, without checking the route to your target universities.
- Switching boards in Class 11 without preparing for the change in style.
- Assuming entrance exam preparation fits as easily alongside IB or A Levels as alongside CBSE.
- Ignoring the subject combinations the school actually offers.

Frequently asked questions
Is IGCSE better than CBSE?
Neither is better for everyone. CBSE fits students aiming at Indian entrance exams; IGCSE fits students heading to A Levels, the IB or universities abroad. Choose by destination.
Can I move from IGCSE to CBSE in Class 11?
Many students do. Check the school's admission rules, and expect to adjust to NCERT content and exam style.
Is the IB recognised in India?
Yes. The Association of Indian Universities recognises the IB Diploma; each university sets its own admission rules.
Key takeaways
- CBSE: national board with NCERT and board exams in Classes 10 and 12.
- ICSE and ISC: CISCE's Class 10 and 12 exams.
- IGCSE: Cambridge's course for ages 14 to 16, leading to A Levels or IB.
- IB: the Diploma Programme for Classes 11 and 12.
