Analysis of Arizona's policies

Arizona stops short of requiring that objective evidence of student learning be the preponderant criterion of its teacher evaluations.

The state now requires the use of an evaluation framework that includes quantitative data on student academic progress. These objective data must account for between 33 percent and 50 percent of outcomes. By school year 2012-2013, districts must use this instrument for annual evaluations of all teachers.

Arizona requires districts to formulate reliable evaluation instruments that include "specific criteria for measuring effective teaching performance in each area of the teacher's classroom responsibility," as well as "an assessment of the competencies of teachers as they relate to the specific criteria for measuring teacher performance."

Further, the state also requires that evaluations include classroom observations "of the certificated teacher demonstrating teaching skills."

Recommendations for Arizona

Require instructional effectiveness to be the preponderant criterion of any teacher evaluation.
Although Arizona's new evaluation system is moving in the right direction, it falls short by failing to require that evidence of student learning be the most significant criterion. The state should either require a common evaluation instrument in which evidence of student learning is the most significant criterion, or it should specifically require that student learning be the preponderant criterion in local evaluation processes. This can be accomplished by requiring objective evidence to count for at least half of the evaluation score or through other scoring mechanisms, such as a matrix, that ensure that nothing affects the overall score more. Whether state or locally developed, a teacher should not be able to receive a satisfactory rating if found ineffective in the classroom. 

Ensure that evaluations also include classroom observations that specifically focus on and document the effectiveness of instruction.
Although Arizona commendably requires classroom observations, the state should articulate guidelines that ensure that the observations focus on effectiveness of instruction. The primary component of a classroom observation should be the quality of instruction, as measured by student time on task, student grasp or mastery of the lesson objective and efficient use of class time.

Utilize rating categories that meaningfully differentiate among various levels of teacher performance.
To ensure that the evaluation instrument accurately differentiates among levels of teacher performance, Arizona should require districts to utilize multiple rating categories, such as highly effective, effective, needs improvement and ineffective. A binary system that merely categorizes teachers as satisfactory or unsatisfactory is inadequate.

State response to our analysis

Arizona recognized the factual accuracy of this analysis. The state added that as of the 2012-2013 school year, local educational agencies (LEAs) will need to map evaluation performance to four levels—highly effective, effective, partially effective and ineffective—for reporting purposes. 

Research rationale

Reports strongly suggest that most current teacher evaluations are largely a meaningless process, failing to identify the strongest and weakest teachers. The New Teacher Project's report, "Teacher Hiring, Assignment and Transfer in Chicago Public Schools (CPS)" (July2007) at: http://www.tntp.org/files/TNTPAnalysis-Chicago.pdf, found that the CPS teacher performance evaluation system at that time did not distinguish strong performers and was ineffective at identifying poor performers and dismissing them from Chicago schools. See also Brian Jacobs and Lars Lefgren, "When Principals Rate Teachers," Education Next (Spring 2006). Similar findings were reported for a larger sample in The New Teacher Project's The Widget Effect (2009) at: http://widgeteffect.org/.  See also MET Project (2010).

A Pacific Research Institute study found that in California, between 1990 and 1999, only 227 teacher dismissal cases reached the final phase of termination hearings. The authors write: "If all these cases occurred in one year, it would represent one-tenth of 1 percent of tenured teachers in the state. Yet, this number was spread out over an entire decade." In Los Angeles alone, over the same time period, only one teacher went through the dismissal process from start to finish. See Pamela A. Riley, et al., "Contract for Failure," Pacific Research Institute (2002).
That the vast majority of districts have no teachers deserving of an unsatisfactory rating does not seem to correlate with our knowledge of most professions that routinely have individuals in them who are not well suited to the job. Nor do these teacher ratings seem to correlate with school performance, suggesting teacher evaluations are not a meaningful measure of teacher effectiveness. For more information on the reliability of many evaluation systems, particularly the binary systems used by the vast majority of school districts, see S. Loeb et al, "Evaluating Teachers: The Important Role of Value-Added." The Brookings Brown Center Task Group on Teacher Quality (2010). 

There is growing evidence suggesting that standards-based teacher evaluations that include multiple measures of teacher effectiveness—both objective and subjective measures—correlate with teacher improvement and student achievement. For example see T. Kane et al, "Evaluating Teacher Effectiveness." Education Next Vol 11 No. 3 (2011); E. Taylor and J. Tyler, "The Effect of Evaluation on Performance: Evidence from Longitudinal Student Achievement Data of Mid-Career Teachers." National Bureau of Economic Research (2011); as well as Herbert G. Heneman III, et al., "CPRE Policy Brief: Standards-based Teacher Evaluation as a Foundation for Knowledge- and Skill-based Pay," Consortium for Policy Research, 2006.
