The Supreme Court's 2025 judgment mandating TET for in-service teachers raises fundamental questions about retrospective application of eligibility norms and federalism. Critically analyse.

Article 21A guarantees not merely access to school but quality schooling. In Anjuman Ishaat-e-Taleem Trust (1 September 2025), the Supreme Court made the Teachers' Eligibility Test compulsory even for serving Class 1–8 teachers of non-minority schools [1] — unsettling both settled service expectations and State autonomy.

The Court's justification

• Qualification attaches to the post: TET flows from Section 23(1), RTE Act, 2009 read with the NCTE notification of 23 August 2010 [3][4], so it conditions continuance, not merely entry.
• Operation is prospective: a two-year compliance window was given, teachers with five years or less to superannuation were exempted, and non-compliance triggers compulsory retirement with terminal benefits, not dismissal [1].
• In review, the Court reaffirmed TET as a constitutional necessity under Article 21-A, dismissing the batch of petitions on merits [2].

Concerns over retrospective norm-setting

• Legitimate expectation: pre-2010 appointees were lawfully recruited when no TET existed; loss of office now penalises conduct valid at the time.
• Proportionality: bridge courses, in-service training under NEP 2020's teacher-development vision, or withholding promotion could secure quality with less hardship.
• Equity: older, rural and tribal-area teachers face unequal access to preparation; a single test certifies eligibility, not classroom competence.

Federal friction

• Education is Entry 25, List III; service conditions of State-cadre teachers are State-framed, yet a uniform judicial deadline narrows that discretion.
• Uttar Pradesh, Tamil Nadu and teachers' bodies pleaded administrative disruption; relief came only through Article 142, extending compliance to 31 August 2028 [2].
• States must scale TET conduct for lakhs of serving teachers within this window — a significant unfunded implementation burden.

The judgment rightly places the child's right above institutional inertia, but its promise depends on execution. Cooperative Centre–State planning — frequent test cycles, bridge remediation and mentoring — can convert a compliance deadline into genuine capability-building, honouring both Article 21A and the teacher's dignity of livelihood.
