A teacher in a government school in Kerala notices that a 9-year-old student, despite being in Class 4, struggles significantly with basic reading and arithmetic.

According to the provisions of the Right to Education (RTE) Act, 2009 (as amended), what is the most appropriate action the teacher should take regarding this student's academic progress?

Accepted Answer

C. Provide continuous and comprehensive evaluation, identify specific learning gaps, and offer individualized remedial support within the school to ensure progression. — The RTE Act, even after amendments allowing detention at certain stages (Class 5 & 8), strongly emphasizes continuous assessment and providing intensive remedial support to ensure every child achieves age-appropriate learning outcomes.
