HARRISBURG (AP) – PA school superintendents are calling for more concrete recommendations from the Wolf Administration as they make decisions on how, and whether, to welcome students back to the classroom this fall. A superintendents group says the state’s existing reopening guidance for schools is too vague, and superintendents and school boards need more help from the PA Department of Health about how to do it safely. The Wolf Administration has largely shunned a one-size-fits-all approach in a sprawling state where the coronavirus has wreaked havoc in some heavily populated counties while barely touching others.
