(1) a community with an ADM of at least 10, but not more than 100, shall be counted as one school;
(2) a community with an ADM of at least 101, but not more than 425, shall be counted as
(A) one elementary school, which includes those students in grades kindergarten through six; and
(B) one secondary school, which includes students in grades seven through 12;
(3) in a community with an ADM of greater than 425, each facility that is administered as a separate school shall be counted as one school, except that each alternative school with an ADM of less than 175 shall be counted as a part of the school in the district with the highest ADM.
(b) Notwithstanding (a)(3) of this section and for purposes other than calculations under AS 14.17.450, a charter school shall be counted as a separate school if the charter school has an ADM of at least 150 students.
(c) Notwithstanding (a)(2) and (a)(3) of this section, in a community with an ADM of greater than 425 that has only one facility administered as a school for students in grades kindergarten through 12, the number of schools for the community shall be counted under (a)(2) of this section.
