school open enrollment; tribal students

HB 4107 amends Arizona's school open enrollment law to specifically include tribal students living on tribal lands outside school district boundaries. It defines "resident transfer pupil" to allow these students to enroll in the three closest school districts based on the shortest distance from their home. This directly affects tribal students who previously faced enrollment barriers due to living outside district lines. The bill clarifies that tribal land includes federally recognized tribal territories, enabling these students to access schools in nearby districts without residency requirements. The change modifies existing definitions under Arizona Revised Statutes §15-816, not creating new funding or curriculum.
