    School Entry Health Exam Requirement:

    A CHDP physical examination is required for all students entering first grade. However, it is strongly recommended that your child has the CHDP physical before entering Kindergarten. If completed prior to Kindergarten, this exam will count toward the first grade physical, and will give your child a head start should there be any problems such as vision or hearing difficulties.
