amend the process by which certain school districts calculate the general fund base percentage.

HB 1131 amends how South Dakota school districts calculate their fall enrollment for state education funding. The bill specifically requires districts to exclude students residing in residential treatment facilities (when the facility operates the education program) from their enrollment count used in the funding formula. This change directly affects school districts serving students in such facilities, potentially altering their state funding amounts based on revised enrollment calculations. The amendment clarifies an existing definition within the state's education funding structure without changing other elements like teacher salary formulas or English learner adjustments.
