Under current law, GS 115C-84.2(d) provides authority to local boards of education to determine the opening and closing dates for public schools under GS 115C-84.2(a)(1). However, the local boards must comply with specified parameters for the opening and closing dates of public schools as provided. Amends GS 115C-84.2(d) to allow Craven County Schools to open as early as August 11 (currently, no earlier than the Monday closest to August 26), excluding year-round schools. Deletes the provisions of subsection (d) concerning waiver of the requirements upon a showing of good cause. Adds new language to GS 115C-174.12 permitting assessments to be given before the conclusion of the fall semester for local boards that have implemented a school calendar that concludes the fall semester prior to December 31. Applies beginning with the 2021-22 school year and expires at the conclusion of the 2021-22 school year.
