What is CBSE Board? ~ Structured Learning for Strong Academic Foundations

The Central Board of Secondary Education (CBSE) is a national educational board in India responsible for regulating and supervising the development of secondary and higher secondary education in CBSE-affiliated schools across the country and abroad. 

Established in 1962, the CBSE is renowned for its comprehensive curriculum, emphasis on academic excellence, and commitment to holistic development.

The CBSE curriculum encompasses several subjects, including languages, sciences, mathematics, social sciences, and regional languages. 

The duration of the CBSE program is generally 10 years, covering classes from 1st to 10th grade for secondary education, and an additional 2 years of higher secondary education for 11th and 12th grades. The students are evaluated continuously through formative and summative assessments.

The CBSE Class 10 board exam, known as the All India Secondary School Examination (AISSE) for CBSE students, is conducted annually in February or March. 

For higher secondary education (classes 11-12), the CBSE Class 12 board exam, officially called the All India Senior School Certificate Examination (AISSCE), is held in February or March each year.

IGCSE Cambridge Board vs CBSE Board: Real Difference Between CBSE and IGCSE

I. Curriculum 

The difference between Cambridge and CBSE stems from their distinct educational philosophies, structures, and approaches.

The key difference between CBSE and Cambridge is that the Cambridge curriculum is flexible, allowing schools and students to choose from a diverse range of subjects based on their interests, strengths, and future career aspirations. 

Whereas the CBSE curriculum follows a more standardised approach, with a prescribed set of subjects aimed at holistic development.

Additionally, the Cambridge curriculum in India emphasises practical skills through hands-on learning experiences and encourages students to apply their knowledge in real-world contexts. 

While CBSE also offers a range of subjects, the options are comparatively limited, especially at the secondary level. Here, the focus lies on providing a well-rounded education covering core subjects.

II. Assessment 

Assessment in the IGCSE Cambridge International curriculum includes a combination of written examinations, coursework, and practical assessments, enabling students to demonstrate their understanding and skills in various ways. 

The Cambridge IGCSE exam serves as a qualification towards the International Certificate of Education (ICE) for advanced ‘O’ level, opening doors to pursue higher education on a global scale.

Meanwhile, the CBSE assessments include both internal assessments conducted by schools and external board examinations. 

The emphasis is on comprehensive evaluation, including practical skills and project work. 

CBSE-affiliated schools conduct the All India Secondary School Examination (AISSE) and All India Senior School Certificate Examination (AISSCE) at the end of the tenth and twelfth grades, respectively, determining their future educational and career paths.

III. Language of Instruction

In the Cambridge IGCSE syllabus, English is predominantly the language of instruction. 

Most IGCSE schools in Chennai across the globe conduct their classes, assessments, and examinations in English. 

However, there is flexibility for Cambridge curriculum schools to offer subjects in other languages, depending on the region and student demographics, allowing students to study in their native language.

Similarly, the CBSE curriculum primarily uses English as the medium of instruction in affiliated schools, including communication, textbooks, and assessments. 

While Hindi is a secondary language of instruction in some CBSE schools, especially in northern India, the emphasis remains on English due to its importance in professional settings.

IV. Grading System

In the IGCSE board schools in India, the grading system ranges from A* to G, with A* denoting the highest level of achievement. 

This grading system provides a clear indication and provides a nuanced differentiation of students' abilities and achievements.

Whereas the CBSE curriculum implements a grading system ranging from A1 to E, with A1 representing the highest grade attainable. 

The CBSE grading system also provides a Cumulative Grade Point Average (CGPA) based on the grades obtained in different subjects, providing a comprehensive overview of a student's academic performance across multiple subjects.

V. Recognition

The IGCSE curriculum is widely recognised and accepted by universities and employers globally. 

Its rigorous academic standards and international outlook make it highly valued for admission to universities worldwide and for employment opportunities internationally.

Similarly, the CBSE curriculum is recognised within India and is accepted by many universities and institutions across the country. 

While CBSE qualifications primarily cater to the Indian educational system, they are also respected by some international universities and employers, particularly those seeking Indian students.

VI. Teaching Approach  

The IGCSE curriculum prioritises interactive and inquiry-based learning, fostering student engagement and critical thinking. 

Through discussions, group activities, and hands-on experiments, teachers stimulate participation and problem-solving skills. 

Encouraging practical learning, the best IGCSE schools in Chennai, like Aachi Global School, integrate subjects through cross-curricular projects, preparing students for real-world challenges with a holistic understanding.

CBSE employs a balanced mix of traditional and modern teaching methods, integrating conventional approaches like lectures with innovative techniques such as multimedia presentations. 

With an emphasis on conceptual understanding, teachers use examples and visual aids to deepen comprehension, steering away from rote memorisation.

IGCSE Cambridge Vs CBSE Board: Which is Better?

Ultimately, both CBSE and IGCSE offer strong educational foundations, but their strengths lie in different areas. 

The CBSE board is ideal for families seeking a structured, nationally recognised curriculum with a strong focus on core academic disciplines and preparation for Indian competitive exams. Its consistency and affordability make it a reliable choice across diverse regions in India. 

On the other hand, the IGCSE Cambridge curriculum stands out for its international perspective, flexibility in subject choice, and emphasis on inquiry-based, experiential learning, making it especially beneficial for students aiming for global opportunities in higher education or careers. 

Choosing between the two depends on your child’s learning style, long-term goals, and preferred academic environment. At the end of the day, both boards are committed to nurturing capable, confident, and future-ready individuals. The right choice isn’t about which board is better; it’s about which board is better for your child.
