Under current law, GS 115C-84.2(d) sets the parameters within which local boards of education must determine the opening and closing dates of public schools under subdivision (a)(1) of the statute.  Amends GS 115C-84.2(d) to require schools to open no earlier than August 10 (currently, prohibited from opening earlier than the Monday closest to August 26), excluding year round schools. Deletes the provisions of subsection (d) concerning waiver of opening date requirements upon a showing of good cause. 

Amends GS 115C-175.12(a)(4) (governing student testing procedures) to permit a local board of education that has implemented a school calendar that concludes the fall semester prior to December 31 to administer assessments before the conclusion of the fall semester. 

Effective beginning with the 2023-24 school year.
