Hyderabad: The Telangana government will file a review petition against the Supreme Court’s September 1 ruling which made the Teacher Eligibility Test (TET) mandatory for all teachers handling classes 1 to 8. The state will seek exemption for teachers recruited before 2011, official sources confirmed on Tuesday. The move comes after strong representations from teacher MLCs and unions, including the Progressive Recognised Teachers’ Union (PRTU) and United Teachers’ Federation (UTF), who met Chief Minister A. Revanth Reddy and urged him to intervene. Nearly one lakh teachers in Telangana are likely to be affected. Teachers have also appealed to Union minister G. Kishan Reddy and Union education minister Dharmendra Pradhan for relief.
