TN TET Eligibility 2026: Qualification and Age Guide

TN TET eligibility depends on two things: the paper you want to take and the type of session being held. The Teachers Recruitment Board (TRB), Tamil Nadu, sets the rules in each notification. Paper I (Classes I to V) is mainly for candidates with a teacher-education diploma, and Paper II (Classes VI to VIII) is mainly for graduates with a B.Ed, with a few other recognised routes for both.

The last open cycle, TNTET 2025 (Notification No. 03/2025), accepted any candidate who met the qualification and was at least 18 years old as on 1 July 2025. The 2026 special sessions, including Notification No. 02/2026 dated 26 October 2026, are open only to working teachers. This page explains the qualification routes for each paper, the percentage rules and relaxations, the age limit, the extra conditions for the special sessions and the common reasons applications fail.

TN TET Eligibility at a Glance

Open Cycle and Special TNTET: Who Can Apply

As of 4 November 2026, TRB has not announced the next open cycle. Fresh B.Ed and D.El.Ed candidates should prepare now and watch the official website for the notification.

Educational Qualification for Paper I

Paper I qualifies you for primary teaching (Classes I to V). You need one of these combinations.

Route 2 applies to candidates whose diploma falls under the NCTE 2002 regulations. Check the exact wording in your notification before relying on the 45% route.

Educational Qualification for Paper II

Paper II qualifies you for upper-primary teaching (Classes VI to VIII). You need one of these combinations.

Matching Your Degree to the Subject Section

Paper II has a 60-mark subject section. Mathematics and Science teachers take Mathematics and Science, Social Science teachers take Social Science, and teachers of other subjects may choose either. The notification links the section to the subject you teach or are qualified to teach. Recruitment notifications for subject posts set their own degree rules, so choose the section that matches the post you plan to apply for.

Minimum Percentage and Relaxation

• The 50% standard: Most routes need at least 50% in Higher Secondary or graduation, depending on the route.

• 45% for reserved categories in Paper II: SC, ST, BC, MBC, DNC and candidates with disabilities can qualify for Paper II with 45% in graduation and a B.Ed, as per NCTE norms.

• 45% under NCTE 2002 norms for Paper I: Applies to the Higher Secondary plus diploma route under those regulations.

• Percentage is on the qualifying exam: Use the aggregate percentage shown on your mark sheet. If your university awards a CGPA, follow the conversion method stated by the university and keep the conversion certificate ready.

These relaxations apply to the qualification only. The qualifying marks in the TN TET exam itself are separate: 60% for General, 50% for BC, BC(M) and MBC/DNC, and 40% for SC, SC(A) and ST. For PwD candidates it was 50% in TNTET 2025 and has been reported as reduced to 40% from 2026. Details are on the TN TET cut-off page.

TN TET Age Limit

Because there is no upper age limit, there is no category-wise age relaxation for TN TET. Age limits for actual teaching posts are set separately in each TRB recruitment notification.

Eligibility for the Special TNTET for Working Teachers

The 2026 special sessions exist so that serving teachers can meet the TET requirement. Under Notification No. 02/2026, you can apply only if all of these apply to you:

• Post: You work as a Secondary Grade Teacher, BT Assistant, BRTE, an equivalent-cadre teacher or an IEDSS special education teacher.

• Appointment date: You were appointed on or before 1 September 2025 and are still in service.

• School type: You work in a government, government-aided or recognised unaided school in Tamil Nadu.

• Pay basis: You are on time scale, consolidated pay or part-time pay.

• Qualification: You hold the prescribed qualification for the paper as on 26 October 2026.

Serving teachers who have not yet cleared TET can apply, and so can TET-qualified teachers who want to take it again for promotion purposes. You must upload a service certificate in the Annexure-I format.

Qualification Cut-Off Date and Pending Results

Each notification fixes a date by which you must hold the qualification. For Notification No. 02/2026, it is the notification date, 26 October 2026. Whether final-year students or candidates awaiting results can apply depends on the notification for that cycle, so read that clause before applying. If you apply without the required qualification on the stated date, your candidature can be rejected at any stage.

Attempts and Certificate Validity

• No attempt limit: The recent notifications reviewed for this page do not cap the number of times you can take TN TET.

• Lifetime certificate: A Tamil Nadu government order of 2021 made the TN TET certificate valid for life. It was earlier valid for seven years.

• Separate certificates: Paper I and Paper II are certified separately, so you can add the second paper later.

The certificate is an eligibility condition, not an appointment. Teaching posts are filled through separate TRB recruitment notifications.

Eligibility Examples

These examples show how the rules apply. They are illustrations only; your notification decides your case.

• Higher Secondary 62% and D.El.Ed: Eligible for Paper I through route 1. Not eligible for Paper II without a degree.

• B.Sc 55% and B.Ed: Eligible for Paper II through route 2, and for Paper I through the graduation with B.Ed route. Can take both papers with separate applications.

• B.A 47% and B.Ed, BC category: Below 50%, but eligible for Paper II through the 45% route for reserved categories. Not eligible for Paper I through the B.Ed route, which needs 50% in graduation.

• B.A 47% and B.Ed, General category: Not eligible for Paper II through the B.Ed routes, which need 50% for General candidates.

• Working BT Assistant appointed in 2019 without TET: Eligible for the special TNTET under Notification No. 02/2026, provided the qualification for the chosen paper is met.

• Teacher appointed in October 2025: Not eligible for the special session, because the appointment is after 1 September 2025. Wait for the next open cycle.

Who Is Not Eligible

• Fresh candidates for the special sessions: Candidates who are not serving teachers cannot apply to Notification No. 02/2026.

• Teachers appointed after 1 September 2025: They fall outside the special session conditions.

• Below the minimum marks: Candidates whose Higher Secondary or graduation percentage is below the route's minimum.

• Unrecognised courses: Diplomas or degrees from institutions not recognised for teacher education.

• Wrong paper: A Higher Secondary plus diploma holder applying for Paper II without the required graduation.

Application Fee and Documents

Keep these ready: photograph and signature in the required size, Higher Secondary and degree mark sheets, diploma or B.Ed certificate, community certificate, disability certificate if applicable, and for the special sessions, the Annexure-I service certificate. Dates and the full application process are on the TN TET exam overview.
