NIOS 18-month D.El.Ed course is valid professional qualification for T-TET eligibility for in-service teachers.

The 18 petitioners were untrained in-service elementary teachers working in various government-aided or private unaided schools.

Following a 2017 mandate by the Ministry of Human Resource Development (MHRD), all such teachers were required to obtain minimum professional qualifications by March 31, 2019, via the National Institute of Open Schooling (NIOS).

The petitioners completed the 18-month Diploma in Elementary Education (D.El.Ed) via the Open and Distance Learning (ODL) mode within the deadline.

They subsequently appeared for the Tripura Teachers’ Eligibility Test (T-TET) 2024 and qualified. However, the Teachers Recruitment Board Tripura (TRBT) rejected their candidatures during document verification, alleging that their D.El.Ed results were published after March 31, 2019.

1. Whether the 18-month D.El.Ed diploma completed through NIOS is a valid eligibility criterion for the issuance of TET certificates and teacher appointments.

2. Whether the rejection of the petitioners' candidature on the ground of result publication date (post-March 31, 2019) is legally sustainable.

The Court applied Section 23(2) of the Right of Children to Free and Compulsory Education (RTE) Act, 2009 (as amended in 2017), which extended the period for untrained in-service teachers to acquire qualifications to March 31, 2019.

It relied on the National Council for Teacher Education (NCTE) recognition order dated September 22, 2017, which reduced the D.El.Ed duration from 24 to 18 months for in-service teachers by subsuming the 6-month internship.

Crucially, the Court followed the precedent set by the Supreme Court in Viswanath v. State of Tripura (Order dated 10.12.2024), which held that the 18-month diploma is valid for those in employment as of August 10, 2017.

The Court determined that the case was squarely covered by its previous judgments in WP(C) No. 242/2025 and WP(C) No. 243/2025.

Reasoning focused on the fact that the petitioners were in active service as of August 10, 2017, making them eligible for the "one-time window" granted by the Parliament and NCTE to regularize their qualifications.

The Court rejected the State's technical objection regarding the result publication date, noting that the academic activities and the course itself were completed within the statutory deadline of March 31, 2019, as mandated by the MHRD and NCTE.

Since the NCTE is the sole academic authority for teacher qualifications, the state authorities could not ignore its guidelines or the Supreme Court's clarification regarding the validity of the 18-month ODL diploma.

It directed the respondent authorities to issue T-TET Certificates to the petitioners within six weeks. The petitioners are permitted to participate in the recruitment process initiated by the notification dated February 21, 2026. However, the Court granted liberty to the respondents to verify that each petitioner was indeed in employment in a government, government-aided, or unaided private school as of August 10, 2017.
