TX HB236

Replaces "average daily attendance" (ADA) with "average enrollment" (AE) as the basis for calculating public school funding throughout the Texas Education Code and related statutes

Defines average enrollment as the average number of students enrolled in a school district during a school year, rather than the previous calculation based on actual daily attendance divided by instructional days

Requires the commissioner to adopt rules determining the method to calculate average enrollment and establishing minimum instructional time requirements for districts to receive full or partial funding

Removes provisions related to flexible year programs and flexible school day programs that previously had special ADA calculation methods, streamlining the funding formula

Applies the enrollment-based funding change across multiple code sections including charter school funding, special education allotments, career and technology education, bilingual education, facilities funding, and wealth equalization calculations under Chapters 46, 48, and 49
