The Central Teacher Eligibility Test was held on Sunday in four cities across the State.
The exam, which was originally scheduled to be held in July last year, was postponed because of the COVID-19 pandemic.
Candidates who intend to teach students of Classes 1 to 5 have to take up Paper 1 and candidates who wish to teach students from Classes 6 to 8 have to write paper 2 of the examination.
The papers were scheduled in two shifts.
In Tamil Nadu, the exam was conducted in Chennai, Coimbatore, Madurai and Tiruchi.
