Elementary teacher allocations based on the prototypical schools formula provided in RCW 28A.150.260 and the Omnibus Appropriations Act for grades K-3 will be based upon budgeted K-3 enrollment as stated in the F-203 revenue estimate from September through December for the year budgeted. Districts, charter schools, and tribal compact schools will also input their estimated K-3 class size for purposes of funding from September through December. K-3 enrollment will not include student full-time equivalent (FTE) enrolled in alternative learning experience programs that meet the requirements of WAC 392-121-182. Funded class size starting with January apportionment will be based on the actual average annual FTE enrollment reported in the P-223. Districts, charter schools, and tribal compact schools must meet the legislative compliance requirements of K-3 class size funding in order to generate the full allotment.
