According to the available figures, around 54,000 engineering seats are still vacant in Tamil Nadu after the first three major rounds of the TNEA counselling process. Students who did not apply earlier for engineering admission after completing their Class 12 examinations, as well as eligible candidates who have cleared their supplementary examinations, can participate in the supplementary counselling process.

The TNEA supplementary counselling registration is being conducted through the official TNEA website. Eligible candidates can submit their applications until August 31, 2026.

Tamil Nadu Has 418 Engineering Colleges Offering Around 2.65 Lakh Seats

• Anna University and its constituent colleges

• Government engineering institutions

• Government-aided colleges

• Central government institutes

• More than 200 private engineering colleges

Together, these institutions offer approximately 2.65 lakh engineering seats across various engineering and technology programmes.

The TNEA counselling process plays a major role in filling engineering seats under the applicable admission categories and quota structure.

TNEA 2026: Over 1.45 Lakh Engineering Seats Filled in Three Main Rounds

During the first three main rounds of the TNEA 2026 counselling process, a total of 1,45,224 engineering seats have been filled.
