(1) School district trustees may apply to the Superintendent of Public Instruction for increased ANB for the initial year of operation of a full-time kindergarten program as provided in 20-9-313, MCA.

(a) determine the average prior year kindergarten enrollment for the semiannual enrollment counts;

(b) multiply the amount calculated in (2)(a) by the anticipated percentage of kindergarten students enrolled in the district in 20XX-1, rounding the percentage to two decimal places (i.e., XX.XX%);

(c) recalculate the district's ANB per ARM 10.20.102 using the adjusted average kindergarten enrollment count calculated in (2)(b); and
