In Indian school administration, CRC stands for Cluster Resource Center — a local hub that supports a cluster of nearby government schools with academic guidance, monitoring and teacher support under Samagra Shiksha (earlier SSA). The officer who runs it is the Cluster Resource Center Coordinator (CRCC). The CRC sits below the Block Resource Center (BRC) in the support structure.
In Indian schools
CRCs are part of the government's field structure for schools, concerned with support and reporting rather than a single school's own office work. An individual school still runs its own admissions, fees and attendance, which is the part a school ERP manages.
