It synthesises literature on school-based mental health support, emphasising the importance of early intervention and its impact on academic and emotional well-being. The National Education Policy (NEP) 2020 serves as a key catalyst, promoting a learner-centric model that integrates mental health services within schools. The paper highlights the critical role of teachers in recognising distress and fostering socio-emotional skills in their students.
