The Student Study Team oversees this process to ensure coordinated support for mental wellness. Support is delivered collaboratively, involving teachers, parents, and, in some cases, external professionals to better understand and address each student’s needs.

RIS maintains a dedicated Child Safeguarding Task Force, led by a Designated Safeguarding Lead (DSL), supported by deputies, counselors, and section principals.
