CBSE

Curriculum, learning and subject choice
In Classes 9 and 10, students generally study a broad combination of languages, mathematics, science and social science. In Classes 11 and 12, they select subjects from the options offered by their school. These combinations are often organised into Science, Commerce and Humanities streams, although these are common school-level arrangements rather than fixed CBSE categories. The subjects available and the flexibility to combine them vary between schools.
Assessment, examinations and grading
CBSE assessment includes external board examinations as well as school-based and internal assessments, depending on the class and subject. The Class 10 and Class 12 board examinations are key milestones in the qualification pathway. Some subjects also include practical examinations, projects, periodic assessments or other internal components.
CBSE results are generally reported through marks and grades. For university applications, institutions may consider the student’s subject-wise marks, overall performance and any course-specific eligibility requirements.
Workload, academic pressure and student responsibilities
CBSE students study a broad range of subjects, with the workload becoming more specialised in Classes 11 and 12. Those preparing for competitive examinations such as JEE or NEET may also need to balance schoolwork with additional preparation.
School fees and overall cost in India
CBSE schools range from government institutions to higher-fee private schools. Overall costs depend on the school, location, facilities, transport and extracurricular activities.
University recognition and admissions in India and abroad
CBSE Class 12 is widely accepted for undergraduate applications in India and by universities internationally. Overseas institutions may have additional requirements for Indian applicants, including minimum marks, specific subjects or standardised tests.
Availability of schools and practical considerations in India
CBSE’s extensive school network makes it a practical option for families relocating between Indian cities.

Indian State Boards

Curriculum, learning and subject choice
State Board students generally follow a prescribed curriculum covering languages, mathematics, science and social science during secondary education. In Classes 11 and 12, students typically select subjects according to the options available under their state board and school.
Senior-secondary subject combinations are commonly organised into Science, Commerce and Humanities streams, although the exact structure and available subjects vary. The curriculum may place particular emphasis on the state’s language, regional history and other locally relevant content.
Assessment, examinations and grading
State Boards generally use external examinations at key secondary and senior-secondary stages, supported by school-based assessments and practical examinations where applicable.
The examination structure, marking scheme, grading system and weight assigned to internal assessment differ between states. Students should refer to the relevant board’s current examination regulations rather than assume that all State Boards follow the same system.

Workload, academic pressure and student responsibilities
State Board students study a prescribed range of subjects, with the workload becoming more specialised in Classes 11 and 12. The academic experience depends on the state syllabus, school teaching methods, examination expectations and the student’s chosen subject combination.
Students preparing for competitive examinations such as JEE or NEET may also need additional preparation, particularly when the entrance examination syllabus or question style differs from their school curriculum.
School fees and overall cost in India
State Board education is available through government, government-aided and private schools. Fees therefore vary considerably depending on the type of institution, location, facilities and additional services.
Government schools may offer a more affordable route, while private State Board schools can have higher fees depending on their facilities and academic offerings.
University recognition and admissions in India and abroad
State Board Class 10 and Class 12 qualifications are used for admission to further education and undergraduate programmes in India, subject to the eligibility requirements of individual universities and courses.
Students applying to Indian universities may need to meet minimum marks, subject combinations and entrance examination requirements. Those applying abroad should check how their particular State Board qualification is evaluated by the university and whether additional academic documentation is required.
Availability of schools and practical considerations in India
State Board schools are widely available across their respective states, including smaller towns and rural areas. This can make them a practical option for families who want access to schools within their local education system.
For families relocating between states, however, differences in language requirements, syllabus coverage and examination patterns may need to be considered. Parents should also check whether a school offers the subject combination their child intends to pursue in Classes 11 and 12.

Cambridge IGCSE

Curriculum, learning and subject choice
IGCSE allows students to select individual subjects from their school’s offerings, including languages, sciences, humanities, business and creative or technical subjects.
Assessment, examinations and grading
Cambridge IGCSE assessment varies by subject and may include written, oral or practical examinations and coursework. Some syllabuses offer Core and Extended options, which affect the content assessed and available grades. Results use either the A*–G or 9–1 grading scale, depending on the syllabus.
Workload, academic pressure and student responsibilities
IGCSE students manage several subjects and assessment formats, which may include written examinations, practical work, coursework and oral assessments.
School fees and overall cost in India
IGCSE is generally offered by private and international schools in India, with fees varying by location, facilities and academic offering.
University recognition and admissions in India and abroad
Cambridge IGCSE is an established international secondary qualification and is generally treated as comparable to the Class 10 stage in India, subject to the relevant equivalence requirements. It is not normally sufficient on its own for undergraduate university admission. Students typically progress to a senior-secondary qualification such as A Levels or the IB Diploma Programme before applying to university.
Availability of schools and practical considerations in India
IGCSE is more widely available in major Indian cities than in smaller towns and is less widespread than CBSE.

IB Diploma Programme

Curriculum, learning and subject choice
Students select six subjects, generally choosing one from each of the IB’s six subject groups:
  • Studies in Language and Literature
  • Language Acquisition
  • Individuals and Societies
  • Sciences
  • Mathematics
  • The Arts
However, students may choose an additional subject from certain other groups instead of taking a subject from the Arts group. 
Students generally take three subjects at Higher Level (HL) and three at Standard Level (SL), alongside the Diploma Core: Theory of Knowledge (TOK), the Extended Essay (EE) and Creativity, Activity, Service (CAS).
Assessment, examinations and grading
IB DP assessment combines external examinations with internal assessments, coursework, investigations and practical or oral components, depending on the subject. Each subject is graded from 1–7, giving a maximum of 42 points. Students can earn up to three additional points through TOK and the Extended Essay, bringing the maximum Diploma score to 45. CAS is compulsory but is not graded, and students must meet the other Diploma requirements to receive the qualification.
Workload, academic pressure and student responsibilities
IB students must balance six subjects, internal assessments and examinations with the Diploma Core. This includes an independent research essay of up to 4,000 words, TOK and sustained CAS activities, making time management an important part of the programme.
School fees and overall cost in India
The IB DP is generally offered by private and international schools in India, with fees varying by institution, location, and facilities.
University recognition and admissions in India and abroad
The IB Diploma is an internationally recognised senior-secondary qualification and is accepted by universities in many countries. Universities may assess the overall Diploma score, individual subject grades and the student’s HL subject choices.
For Indian university admissions, IB students should check the current equivalence and eligibility requirements as well as the subject-specific criteria of their intended institutions. Requirements can differ by course and university.
Availability of schools and practical considerations in India
IB DP schools are concentrated in larger Indian cities. Parents should check that a school offers the Diploma Programme, as not every IB World School provides it.

Cambridge International A Levels

Curriculum, learning and subject choice 
Cambridge International A Levels are pre-university qualifications generally taken by students aged 16–19. Students typically specialise in three or four subjects, allowing for greater depth than broader programmes such as the IB DP.
Assessment, examinations and grading
A Levels are primarily assessed through external examinations, although some subjects include practical or coursework components. Students receive a separate grade for each subject: A*–E for full A Levels and A–E for AS Levels. Depending on the examination route, students may complete AS assessments first or take the full A Level examinations at the end of the course.
Workload, academic pressure and student responsibilities
A Levels involve in-depth study of a smaller number of subjects, with students expected to develop strong subject-specific knowledge and apply concepts to unfamiliar questions.
School fees and overall cost in India
Cambridge International A Levels are generally offered by private and international schools in India. Their fees vary depending on the school, location, facilities and programme.
University recognition and admissions in India and abroad
Cambridge International A Levels are widely accepted for university admission internationally. In India, Cambridge’s published guidance states that Cambridge International A Levels in three subjects meet its stated Grade 12 equivalence criteria.
Availability of schools and practical considerations in India
Cambridge International A Levels are offered by a range of private and international schools in India, often alongside IGCSE. However, not every IGCSE school offers A Levels.

Transitioning Between Boards: What Should Parents Know?

Changing school boards requires students to adapt to differences in subject content, topic sequencing, assessment methods and expectations of independent study. Parents should understand these differences before choosing a new school.

Moving from CBSE to IGCSE

Students moving from CBSE to Cambridge IGCSE usually make the transition at the beginning of the IGCSE course, often around Class 9.
Academic differences to prepare for:
  • Syllabus differences: Topic sequencing and depth may vary, so students may need to cover gaps in their previous learning.
  • Assessment formats: Depending on their subjects, students may encounter coursework, practical examinations and oral assessments in addition to written papers.
  • Question styles: Students may need to adapt to Cambridge command words, question structures and expectations for presenting answers.

Moving from a State Board to CBSE

Students moving from a State Board to CBSE may encounter differences in syllabus coverage, subject sequencing, textbooks and examination patterns. The extent of the adjustment depends on the state board and the class in which the student transfers.
Before enrolling, parents should:
  • Compare the subjects and topics covered in the two curricula.
  • Check whether the student’s previous language and subject choices meet the school’s admission requirements.
  • Identify any gaps in Mathematics, Science, Social Science or other subjects.
  • Understand the CBSE assessment structure and examination expectations.

Moving from a State Board to IGCSE, A Levels or the IB DP

Students moving from a State Board to an international curriculum may need to adapt to different teaching and assessment approaches.
For IGCSE, the transition may involve a change in subject selection, question styles and assessment formats. Students progressing directly into A Levels or the IB DP after Class 10 should check the school’s entry requirements and the academic foundations expected for their chosen subjects.
For the IB DP, students should be prepared for six subjects, HL and SL choices, internal assessments and the Diploma Core. For A Levels, they should be ready to specialise in a smaller number of subjects and study them in greater depth.
Parents should compare the student’s previous syllabus with the new curriculum and speak to the receiving school’s admissions team before making the transition.

Moving from IGCSE to A Levels

IGCSE students progressing to A Levels move from a broad subject selection to in-depth study of a smaller number of subjects.
What changes during the transition?
  • Subject selection: Students commonly choose three or four subjects based on their strengths, interests and university plans.
  • Greater depth: A Levels build on IGCSE knowledge and require more advanced subject-specific understanding and application.
  • Entry requirements: Schools may set minimum IGCSE grades or subject prerequisites for A Level admission.

Moving from IGCSE to the IB Diploma Programme

Students moving from IGCSE to the IB DP must adapt to a broader programme combining six subjects, internal assessments and the three compulsory Core components.
What students need to prepare for
  • Subject selection: Students should check that their IGCSE subjects provide a suitable foundation for their intended IB subjects and HL choices.
  • Internal assessments: Students must manage coursework, practical work and other internally assessed components alongside examinations.
  • Diploma Core: The Extended Essay, TOK and CAS introduce independent research, critical reflection and ongoing activities beyond regular subject lessons.

Moving from CBSE to A Levels or the IB DP

Students moving from CBSE to A Levels or the IB DP after Class 10 should check subject prerequisites, assessment expectations and any gaps in their previous learning before enrolling.
For students moving to A Levels:
Students move to a smaller number of specialised subjects. They should check university prerequisites and the school’s minimum entry grades before selecting their A Level combination.
For students moving to the IB DP:
Students must adjust to six subjects, HL and SL choices, internal assessments and the Diploma Core. Those accustomed to examination-focused assessment may need time to adapt to ongoing coursework and independent research.

Which Board Is Best for Your Child?

There is no universally best school board. The right choice depends on a student’s academic interests, university plans, learning preferences and the quality of the school.
CBSE may suit students who prefer a structured curriculum and want continuity within the Indian education system.
Indian State Boards may suit families who prefer education within their state’s school system, particularly when regional language instruction, local accessibility and affordability are important considerations.
IGCSE may suit students who want an international secondary qualification with flexibility in subject selection before progressing to senior-secondary studies.
A Levels may suit students with clear academic interests who want to specialise in a smaller number of subjects relevant to their intended university course.
The IB DP may suit students who want to maintain academic breadth while pursuing selected subjects at greater depth and managing the additional Diploma Core requirements.

Factors to Consider Before Choosing a School Board

Beyond the curriculum, parents should consider:
  • Your child’s academic strengths and interests: Consider the subjects they enjoy and the learning environment in which they perform best.
  • Future university and career plans: Check the subject prerequisites for their prospective courses and universities.
  • Subject availability at the school: Confirm that the school offers the required HL, SL or A Level subject combinations.
  • Teaching quality and academic support: Evaluate teachers’ expertise, class sizes and the support available to students.
  • Assessment and workload: Understand how the school prepares students for examinations, coursework and internal assessments.
  • Total cost and affordability: Account for admission, examination and registration fees, learning materials, transport and extracurricular activities.
  • Flexibility and future changes: Consider how easily your child could change schools, subjects or academic pathways if their plans change.
