class size limits; policies; appropriations

Arizona's SB 1647 establishes specific class size limits for public schools, requiring all schools to adopt policies by the 2030-2031 school year. It sets maximum average class sizes (e.g., 18 students for K-3, 25 for 9-12) and prohibits exceeding these limits, with limited exceptions for specialized classes. The bill creates a dedicated "Classroom Site Fund" to support implementation, requiring schools to use these funds primarily for class size reduction, teacher compensation (including performance-based components), and related programs like teacher development. This directly affects all Arizona public schools, K-12, by mandating smaller class sizes and linking funding to compliance.
