HB 236 amends Section 48.005 of the Texas Education Code to shift public school funding calculations from a “daily attendance” basis to an “average enrollment” model. This change impacts how Texas public schools receive funding, basing financial support on the average number of students enrolled rather than on daily attendance rates. The bill includes provisions for calculating enrollment adjustments for districts experiencing significant drops due to circumstances such as military base closures or natural disasters. Additionally, it enables the commissioner of education to set rules regarding the method for calculating average enrollment and minimum instructional hours for eligibility​.
