House committee substitute to the 1st edition makes the following changes. 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 make the opening and closing school dates in the current law (opening no earlier than the Monday closest to August 26 and closing no later than the Friday closest to June 11) applicable only to students attending Hyde County School located on Ocracoke Island. Sets the opening date for students who are dual enrolled in Hyde County Schools and an institution of higher education or for students attending Hyde County Schools that are not located on Ocracoke Island as no earlier than the Monday closest to August 10 and the closing date as no later than the Friday closest to June 11. Amends GS 115C-174.12 allowing assessments to be given before the conclusion of the fall semester if Hyde County has implemented a school calendar that concludes the fall semester prior to December 31. Applies beginning with the 2023-24 school year.
