Amends GS 115C-238.29F(g) to permit charter schools to extend enrollment priority to siblings applying for admission to the charter school at the same time and to children of the school's employees (was, school's principal, teachers, and teacher assistants). Provides that siblings includes, for purposes of this section, half-siblings and step-siblings. Provides that if a lottery is needed under subdivision (5) of this section, the charter school is to enter one surname into the lottery to represent all of the siblings applying at that time (was, provision applied to multiple birth siblings only). Additionally provides that a charter school may offer enrollment priority to a student who was enrolled in the charter school within the previous two school years but left the school to participate in extraordinary educational opportunities or because of vocational opportunities available to the student's parent. Applies beginning with the 2013-14 school year.
