Principal and teacher perceptions of implementation of multiple‑measure teacher evaluation systems in Arizona

School districts in Arizona that piloted new teacher evaluation models in 2012/13 used multiple measures. Information from surveys and focus groups indicates that teachers and principals in these districts view standardsbased teacher observations as the most credible form of evaluation but are open to incorporating student performance and stakeholder survey measures if they are comprehensible, fair, and consistent. Some 39 percent of surveyed teachers from pilot districts agreed that their final classification under the new system accurately reflected their performance, 32 percent indicated that it did not, and 30 percent were undecided.
