This will depend on the makeup of the school, the number of students learning in person or participating in extra-curricular activities. Depending on the number of students, districts/schools may prioritize populations by grade level (focusing on secondary students, for example), student groups (such as students with special needs who cannot wear face coverings or remain socially distant), or individuals who interact with others more (such as sports teams or students who see multiple support staff).
DPH recommends students be tested once per month, potentially on a rotating basis. Districts/schools should develop an operational plan for testing before beginning.
