Amends GS 115C-84.2(a)(1) to provide that a school calendar may include a minimum of either 180 days or 1,000 hours of instruction (was, a minimum of 180 days and 1,000 hours of instruction) covering at least nine calendar months. Allows the local board of education (LEA) to comply with the school calendar requirement in the case of inclement weather by scheduling 1,000 hours of instruction on less than 180 days. Provides that an LEA making a calendar adjustment due to inclement weather meets the minimum 180-day requirement for instruction days. Also provides that teachers employed for a 10-month term are deemed to have been employed for 180 instructional days. Directs that all other employees are to be compensated as if they had worked their regularly scheduled hours for 180 instructional days. Applies only to the Greene County Schools in the 2010-11 school year.
