Step 1: Recall the levels of Primary Health Care (PHC) and the services provided. The Indian primary health care system is structured in tiers: Sub-centre (SC), Primary Health Centre (PHC), Community Health Centre (CHC), Sub-district hospital, and District hospital.
Step 2: Identify where School Health Services are placed. Under the Primary Health Care structure, preventive services are divided into General Services (health education, environmental monitoring, control of endemic diseases) and Care of Vulnerable Groups. School Health Services fall under Care of Vulnerable Groups, alongside Maternal & Child Health Services, Geriatric Health Services, and Occupational Health Services -- all of which are delivered at the PHC level.
Step 3: Eliminate other options. Sub-centre handles basic maternal and child health tasks and first contact care. Subdistrict and District hospitals are secondary/tertiary level facilities not primarily responsible for school health services under the UIP framework.
Conclusion: School health services are organized and delivered at the PHC (Primary Health Centre) level.
