AZ SB1630

Reduces classroom observation requirements from at least two observations to one observation per school year, allowing informal walk-throughs to supplement evaluation methods.

Removes the 60-calendar-day requirement between first and last observations and the restriction on observations within two instructional days of extended school breaks.

Maintains the four-tier teacher performance classification system (highly effective, effective, developing, ineffective) with quantitative student academic progress data accounting for 20-33% of evaluation outcomes.

Preserves confidentiality protections for teacher evaluation reports and allows sharing only with the teacher, district personnel, other school districts/charter schools for employment purposes, and in court proceedings related to teacher competency.

Continues requirements for performance improvement plans, professional development opportunities, and procedures for dismissal or nonrenewal of teachers in the lowest performance classifications.
