Engineering After Diploma (Lateral Entry) in Tamil Nadu: 2026 Guide
Published: 19 August 2026. Diploma holders can join second-year B.E. directly through lateral entry under TNEA. This is an excellent path if you want a degree without repeating first year.

Which branches can you join
You generally join the same or closely related branch as your diploma. A Mechanical diploma holder can join Mechanical B.E. laterally; a Computer Science diploma holder can join CSE or IT B.E. Specific rules vary — confirm at the official portal.
Process steps
- Register separately under lateral entry quota on the TNEA portal during the open window
- Upload diploma mark sheets and certificate
- Attend document verification
- Fill choices from available lateral entry seats
