TNPSC Combined Statistical Subordinate Service Eligibility

TNPSC Combined Statistical Subordinate Service eligibility depends on the post you want. Each post has its own degree requirement, and age limits vary by category. A candidate with a degree in Statistics is eligible for all three posts of the last verified cycle, while others may qualify only for Assistant Statistical Investigator.

The rules below are from the 2022 notification, the latest we could verify. We have not found a newer notification as of 26 October 2026, so treat these as the likely rules, and read the new notification on tnpsc.gov.in before applying.

Eligibility at a glance

Educational qualification

The degree must be from a recognised university. Check that the main subject on your certificate matches the wording of the post, because a degree with Statistics only as an allied subject may not be accepted. If you hold a combination such as Mathematics with Statistics, read the notification text on whether it counts. For graduates in other subjects, the postgraduate route in Operations Research, Econometrics or Mathematical Economics applies to the Assistant Statistical Investigator post.

Age limit

Age is counted as on a reference date given in the notification. In the 2022 cycle it was 1 July 2022.

The notification may set a minimum age as well, normally 18 for government service. Verify the exact figure and reference date in the new notification, as dates change every cycle.

Language and other conditions

• Tamil knowledge: the Tamil eligibility test at SSLC standard is part of Paper II, and you need to clear its minimum mark.

• Citizenship: general conditions for state government posts apply, so read the nationality clause in the notification.

• Character and fitness: selection is subject to verification of character, and a medical standard may apply.

• Reservation: community, women, disability and other reservations follow Tamil Nadu government rules, and supporting certificates are needed.

Who may not be eligible

• Wrong degree subject: graduates whose degree is not among the listed subjects, and who lack the required postgraduate degree.

• Result not declared in time: final-year students whose results are not out by the date the notification requires.

• Over the age limit: candidates above the limit who do not fall in a relaxed category.

• Incomplete or incorrect application: mismatched details can lead to rejection, so use the correction window.

Fee and documents

In the 2022 cycle the registration fee was Rs. 150 and the examination fee was Rs. 100, with exemptions for SC, ST, destitute widows and candidates with benchmark disabilities. Keep degree certificates, a community certificate, a scanned photograph and a scanned signature ready.
