TNEA 2026 SC and SCA Closing Rank: Expected Cutoffs and Seat Availability

TNEA 2026 SC category expected closing marks range from 158 to 189 out of 200 at top government engineering colleges, based on 2025 cutoff trends — with SCA students typically needing 3 to 8 fewer marks than SC for the same seat.

Tamil Nadu Engineering Admissions (TNEA) 2026, conducted by Anna University on behalf of the Directorate of Technical Education (DOTE), allocates seats to SC and SCA students through a marks-based cutoff. TNEA calculates a score out of 200 from Class 12 board marks in Maths, Physics, and Chemistry. Every cutoff mark maps to a TNEA rank, and the last rank allotted in a category per college and branch is the closing rank. With TNEA 2026 counselling scheduled to begin around July 2026, understanding these expected category-wise cutoffs helps students shortlist reachable colleges early.

• TNEA cutoff formula: Maths marks (out of 100) + Physics ÷ 2 + Chemistry ÷ 2 = 200 total.
• SC students receive 15% seat reservation; SCA (Scheduled Caste Arunthathiyar) students receive a separate 3.5% seat reservation — independent of the SC quota.
• Based on 2025 data, SC students need 7 to 21 fewer marks than OC students for the same college and branch.
• SCA closing marks are typically 3 to 8 lower than SC closing marks at the same institution, due to a smaller eligible candidate pool.
• If SCA seats remain vacant after all rounds, they are converted and allotted to eligible SC students as per TNEA norms.

SC and SCA Categories in TNEA 2026

TNEA 2026 follows Tamil Nadu’s state reservation policy. SC (Scheduled Caste) students are allotted 15% of total seats across all participating engineering colleges. Separately, SCA (Scheduled Caste Arunthathiyar) students receive 3.5% of total seats as a dedicated sub-quota — this is not carved out of the SC 15% but is an independent reservation in Tamil Nadu’s engineering admission framework.

Students in both categories are ranked separately within their community pool based on their TNEA cutoff marks. The closing rank for each category is the TNEA rank of the last student allotted a seat in a given college-branch combination during the final counselling round. Because SC and SCA students need lower cutoff marks than OC students for the same seat, their closing ranks (in terms of overall TNEA rank) are numerically higher.

TNEA 2026 Expected SC Category Closing Marks

The table below shows expected SC category closing marks for 2026 at key government and government-aided colleges, based on 2025 TNEA cutoff trends. All marks are out of 200. These are projected figures; official cutoffs will be published on tneaonline.org after each allotment round.

These closing marks translate to different TNEA overall ranks depending on mark distribution in a given year. Students scoring between 178 and 190 marks can typically expect an overall TNEA rank in the range of 5,000 to 30,000, based on 2024–2025 distribution patterns. All figures are expected based on 2025 TNEA trends.

TNEA 2026 Expected SCA Category Closing Marks

SCA (Scheduled Caste Arunthathiyar) students compete in a smaller candidate pool for their 3.5% reserved seats. Because the SCA-eligible population is smaller relative to seats in this sub-quota, SCA closing marks tend to be 3 to 8 marks lower than the SC closing mark at the same college and branch — meaning SCA students can secure a seat with slightly fewer marks than their SC peers.

If SCA seats at a college and branch go vacant after all counselling rounds, Anna University converts them to SC seats — giving SC students an additional opportunity in the supplementary round. Students can track this conversion schedule on the official TNEA portal.

Seat Availability for SC and SCA in TNEA 2026

TNEA 2026 is expected to offer over 1.75 lakh seats across more than 500 government, government-aided, and self-financing engineering colleges in Tamil Nadu. SC and SCA students together account for 18.5% of these seats, providing a large number of reserved openings across all branches and institution types.

Government engineering colleges carry the highest placement value, making their SC and SCA seats the most sought-after. Students whose marks fall short of top government college cutoffs should also consider reputed government-aided colleges, where SC and SCA closing marks are typically 10 to 20 points lower than at Anna University constituent colleges such as CEG, MIT, and ACT.

Factors Affecting TNEA 2026 SC and SCA Closing Ranks

Closing marks and the ranks they correspond to shift from year to year based on several variables:

• Tamil Nadu Class 12 board exam difficulty: A tougher paper in 2026 lowers the overall score distribution, which can ease closing marks across categories.
• Number of eligible SC and SCA applicants: A larger applicant pool tightens competition and pushes closing marks higher within the category.
• Seat matrix changes: New college affiliations, branch approvals, or increased intake directly affect how many seats are available per category per round.
• CSE and IT branch demand: These branches consistently close at the highest marks in every category. Civil Engineering, Mechanical Engineering, and Chemical Engineering tend to remain more accessible.
• Multi-round counselling effect: Closing ranks after the final round are always higher than after round 1. Students should track each round’s data rather than acting on early-round cutoffs alone.

Students targeting top government colleges in the SC category should aim for marks above 182 to have strong chances at CSE or ECE branches, while SCA students may have a slightly lower threshold of around 176 to 178, based on expected 2026 trends derived from 2025 data.
