Move spring enrollment count date one week earlier

HB 23 would change the date used to count student enrollment for school funding calculations in Montana. Specifically, it moves the spring enrollment count from the first Monday in February to the first Monday in January. This adjustment directly affects public school districts, as the updated enrollment count would determine their state funding levels under the average number belonging (ANB) formula. The bill does not alter funding formulas or student eligibility rules, only the timing of one enrollment measurement.
