Eligibility criteria
Eligibility is notification-specific. Candidates must verify the relevant notification and addenda before applying.
| Requirement | General position |
|---|
| Educational qualification | A recognised university degree is generally required. The prescribed qualification and any post-specific preference must be checked for each post. |
| Final-year candidates | The 2025 notification permitted candidates who had written the final-year degree examination to apply for the preliminary test, subject to producing proof of passing before admission to the main examination. |
| Minimum age | For the 2025 notification, candidates had to have completed 21 years; maximum age varied by post and category. |
| Tamil knowledge | The notification sets out acceptable evidence of adequate knowledge of Tamil and the process for candidates who must pass the prescribed language test after appointment. |
| Post-specific conditions | Physical standards apply to Deputy Superintendent of Police (Category-I); disability eligibility and other post-specific conditions also vary. |
| Age concessions and reservation | Apply only as stated in the current notification and applicable Tamil Nadu rules. Supporting certificates may be required. |
Do not rely on a single generic age limit: the maximum age and concessions differ between posts, communities and eligible concession categories.
