Which of the following is NOT a mandated population for screening?

The mandated populations for vision screening typically focus on specific age groups that are crucial for identifying issues early in a child's development. In this context, kindergarten, second grade, and eighth grade screenings are often required to ensure that vision problems are detected and addressed during critical learning periods that can impact academic performance.

High school students, while they may still benefit from vision screenings, are generally not included in the mandated groups because their academic development has already progressed significantly. Programs tend to emphasize earlier education stages where undiagnosed vision issues can have a more pronounced impact on a child's ability to learn and thrive in an educational environment.

Therefore, high school is not considered a mandated population for screening in this specific context, underscoring the fundamental understanding of when intervention is most essential.
