AZ HB2147

Replaces the term "average daily membership" with "average daily attendance" throughout Arizona Revised Statutes Title 15 (Education) and related statutes, changing how student counts are calculated for school funding purposes.

Redefines average daily attendance to measure actual attendance through the first 185 days in session rather than enrollment on four specific snapshot dates, with attendance calculated based on hours attended for high school students.

Modifies student counting and funding calculations for charter schools, online instruction, dropout recovery programs, and joint technical education districts to align with the new attendance-based methodology.

Updates financial reporting, auditing, and budget adjustment procedures to reference average daily attendance instead of average daily membership in determining state aid and revenue control limits.

Makes conforming changes across multiple statutes governing school district operations, special education, facility standards, and election procedures to implement the shift from membership-based to attendance-based student counting.
