TNPSC updates
The TNPSC cutoff is the last qualifying mark for a stage, set where merit meets vacancies for each category. This page explains how it is determined and how to use official cutoff trends sensibly.

How it works
The cutoff is the last qualifying mark for a stage, set by where merit meets vacancies for each category.
TNPSC cutoffs vary by group, category and the communal reservation roster Tamil Nadu follows, so the same exam can close at different marks across categories.
Vacancy count, applicant strength and paper difficulty are the three levers — a harder paper or larger vacancy pool pulls the qualifying mark down, and the reverse pushes it up.
Normalisation, where multiple shifts run, adjusts raw scores before the cutoff is applied, so compare normalised — not raw — marks against it.
Official cutoff notices from earlier cycles on tnpsc.gov.in are the only reliable trend source — coaching estimates published before the official notice routinely miss by a wide margin.

Common questions
Tamil Nadu's communal reservation roster distributes posts across categories, so each category's last-allotted rank lands at a different mark.
Cutoff details generally surface with counselling and allotment records; the commission's official publications are the reliable source rather than coaching estimates.
When an exam runs in multiple sessions, the commission applies its notified normalisation method before merit lists and cutoffs are prepared.
