Please note the following:
"Due to the closure of schools pursuant to the Executive Order(s) issued by the Governor for the COVID-19 crisis and recognizing that such requests need to be incorporated into a school district’s budget, the Department directs all public school districts to accept all parental requests for transportation to charter and nonpublic schools submitted on or before April 15, 2020. The Department deems such Executive Order(s) be a reasonable excuse for a delay under Ed. Law 3635."
Please also note that because of the interaction with public school district budget calendars, I would not anticipate further extensions.
