CBSE Section Increase – Updated Norms 2025

CBSE Section Increase – Updated Norms 2025

The Central Board of Secondary Education (CBSE) has overhauled its section permission policy under the new CBSE Section Increase – Updated Norms 2025.

Announced via Circular No. 13/2025 dated 31 July 2025, this CBSE section increase update replaces the old per-classroom and land-based calculation with a built-up carpet area–based limit that now governs the total number of sections a school can operate — from Balvatika (pre-primary) to Class XII.

In this guide, we’ll break down the new norms, compare them with the previous rules, explain their implications for schools, and use a real-world example to show how they can directly impact your institution.

1. The New CBSE Section Increase Formula – Appendix V (2025 Amendment)

Under the new rules, the maximum number of sections a CBSE-affiliated school can operate depends on its total built-up carpet area — not the number of classrooms. This is a fixed cap, meaning even if you construct more rooms, you cannot exceed the maximum permitted sections for your built-up size.

📊 Amended Appendix V – Built-Up Carpet Area vs. Section Permissions

🔺 Points to Note:

• Schools can add three additional sections for every 400 square meters of built-up area beyond the base requirement.
• The land area shall be utilized only for the purpose of deciding the category of the schools, that is branch school, middle school, secondary and senior secondary level school.
• Even with ample funds and land, a school with 6,200 sqm built-up carpet area cannot exceed 48 total sections.

2. Old Norms vs. New Norms – What’s Changed?

CBSE Section Increase Old Norms (Before July 2025)

Previously, section capacity was linked to land size, with eligibility dependent on infrastructure. For example:

• Up to 2 sections per class for 4,000 sq. m. of land
• Up to 3 sections per class for 6,000 sq. m. of land
• Up to 4 sections per class for 8,000 sq. m. of land

These limits applied only if the school also had one dedicated classroom of at least 500 sq. ft. per section, an adequate library, a fully equipped science laboratory, computer and mathematics labs, music and dance rooms, a medical room with basic first-aid facilities, a staff room for teachers, and sufficient toilets for students and staff.

In short, land size determined the ceiling, but infrastructure readiness decided actual approval.

CBSE Section Increase – Updated Norms 2025 (From July 2025 Onwards)

Now, built-up carpet area alone determines section capacity. As a result, land size no longer affects the cap once affiliation is granted. Furthermore, the revised Appendix V clearly sets built-up carpet area ranges and the corresponding maximum sections for the entire school, from Balvatika to Class XII.

Having more land does not help unless your constructed, usable indoor space meets the benchmark for your desired section count.

3. CBSE Section Increase Rules – Key Implications for Schools

3.1 Fixed Cap Based on Built-Up Area
Even with extra classrooms, you cannot exceed the section limit tied to your total built-up carpet area. Expansion is now tied to construction, not just land. Schools are allowed an equal number of sections for secondary (Classes 9-10) and senior secondary (Classes 11-12) levels. The total sections at these levels cannot exceed one-fourth of the total sections from Balvatika up to Class 10 or 12, with rounding up to the nearest even number if necessary.

3.2 Greater Focus on Indoor Infrastructure
Schools may prioritise vertical construction and multi-storey buildings to increase usable indoor space.

3.3 Possible Overcrowding Risks
If section caps are reached, schools might need to increase students per class, potentially impacting quality.

3.4 Balanced Growth Essential
Playgrounds, labs, and activity areas must scale alongside classrooms to ensure holistic education.

3.5 Addresses Space Constraints & Admission Pressure

Schools with smaller land parcels but sufficient indoor space can now accommodate more students, easing admission pressure while still maintaining adequate facilities for holistic education. This change is particularly beneficial for schools in larger cities, where land availability is limited and every square meter counts.

4. Real-World Example – The 26 Section Scenario

School Profile: XYZ School (For example only)

• Grades: Nursery to Class 10 (including Pre-Primary: Nursery, LKG, UKG)
• Sections/Class: 2
• Total Sections:
  • Pre-Primary (3 grades × 2) = 6 sections
  • Classes I–X (10 grades × 2) = 20 sections
  • Total = 26 sections
• Land Area: 6,000 sqm (previously adequate)

Built-Up Carpet Area Breakdown:

Total Built-Up Carpet Area:
13,000 + 1,200 + 600 + 600 + 500 + 600 + 600 + 600 + 400 + 600 + 4,000 = 22,700 sq ft ≈ 2,108 sqm

Impact:

Old Norms: Could operate all 26 sections

New Norms: 2,108 sqm allows only 18 sections

Shortfall: 8 sections — potentially affecting 300+ students

5. Why This Matters: CBSE Section Increase – Updated Norms 2025

1. Schools That Don’t Abide by the New Limit – May face difficulties in renewals or expansions.
2. Expansion Strategy Shift – Land purchase alone won’t raise limits; carpet area must grow. A school on 6,000 sqmt of land can run four sections per class if the built-up carpet area is 6,200 sqmt or more. In contrast, even a school on a larger plot of 8,000 sqmt or more cannot run four sections per class unless its built-up carpet area also meets the 6,200 sqmt requirement.
3. Urban Constraints – Limited plots in cities will push schools toward vertical builds.
4. Budget & Planning – Infrastructure upgrades become priority before admissions expansion.

6. Recommended Next Steps for Schools

• Audit Current Built-Up Carpet Area – Check compliance with Appendix V.
• Plan Vertical Expansion – Use multi-storey designs to increase usable space.
• Review Section Strengths – Avoid overloading classes without parallel facility upgrades.
• Keep Documentation Ready – Maintain updated plans and certificates for CBSE inspections.

Final Word

The CBSE Section Increase Norms 2025 mark a major shift from land-and-classroom based rules to a built-up area–driven model. While aimed at ensuring adequate learning space, it could challenge schools already operating at high capacity.

In the CBSE framework of 2025 and beyond, your built-up carpet area is just as critical as your land size. Early planning, careful infrastructure design, and compliance audits are now essential for smooth approvals.
