Both are part of the same combined recruitment notification and share the same Prelims and Mains exam. The key difference is that Group 2 posts (like Sub-Registrar, Municipal Commissioner) have an Interview/Oral Test worth 40 marks after Mains, while Group 2A posts (like Revenue Officer, Personal Assistant) do not have an interview — their final selection is based solely on Mains marks. Candidates can apply for both simultaneously in one application.

The minimum educational qualification for TNPSC Group 2 and Group 2A is a Bachelor's degree (Graduation) in any discipline from a recognised university. For a few specific posts like Personal Assistant, typing proficiency in Tamil and English may also be required. 12th pass candidates are not eligible.

The age limit varies by category. Open Competition (OC) candidates must be 18–32 years. BC/BC(Muslim) candidates get an upper age relaxation of 3 years (up to 35). MBC/DNC candidates also get 3 years extra (up to 35). SC/ST candidates get 5 years extra (up to 37). Destitute widows and differently-abled candidates have special relaxations. Age is calculated as of 1 July of the recruitment year.

The Preliminary exam is a Computer Based Test (CBT) of 200 questions and 300 marks, to be completed in 3 hours. It consists of Part A: General Studies (75 questions, 75 marks), Part B: Aptitude & Mental Ability (25 questions, 25 marks), and Part C: General Tamil or General English (100 questions, 100 marks). There is negative marking of 1/3 mark for every wrong answer. The prelims is only a screening test — these marks are not counted in the final merit.
