Amends GS 115C-84.2, concerning the opening and closing dates of public schools, to set the opening date as August 16 and the closing date as June 1 (with contingencies for when those dates fall on the weekend). Upon good cause shown, allows local boards of education to set an opening date of August 9 (with contingencies for when that date falls on the weekend). Applies beginning with the 2019-20 school year.
