School health screening involves determining students' health status and detecting physical defects or improved health. It can be conducted by school doctors, nurses, dentists, and teachers. Screenings include vision testing to check eye functions; hearing testing to measure sound reception; weight and height measurements to monitor growth and development; dental examinations at least once a year to correct defects; pulse checks to monitor for heart conditions; and medical examinations by doctors to ensure accurate health information. The various screenings help identify health issues and ensure students' well-being.
