Identifying Effective Teachers Policy
The state should publicly report districts' distribution of teacher talent among schools to identify inequities in schools serving disadvantaged children.
Providing comprehensive reporting may be the state's most important role for ensuring the equitable distribution of teachers among schools. Massachusetts reports some school-level data that can help support the equitable distribution of teacher talent.
Massachusetts now requires districts to publicly report aggregate school-level data about teacher performance. Beginning in the 2013-2014 school year, the state will report on the summative performance ratings for teachers, aggregated to the school level. As teachers' impact ratings become available, they will also be reported.
Massachusetts has also reported on the percentage of highly qualified teachers. Commendably, these data are reported for each school, rather than aggregated by district. The Revised State Plan for Meeting the Highly Qualified Teacher Goal, published in 2011, compares the percentage of highly qualified teachers in high- and low-poverty schools. However, these data have not been updated since the 2009-2010 school year.

Ensure that school-level teacher effectiveness data is meaningful to the public.
Massachusetts is commended for requiring districts to provide evaluation
ratings and for making these data available to the public. However, as noted in
Goal 3-B, because the summative performance rating is reported separately from
the impact rating, these data may be challenging for the public to
Massachusetts was helpful in providing NCTQ with the facts necessary for this analysis.
Distribution data should show more than just teachers' years of experience and highly qualified status.
The first step in addressing the distribution of teachers is bringing transparency to the issue. States generally report little more than what is required by No Child Left Behind, which highlights years of experience and HQT status. However, while teaching experience matters, the benefits of experience are largely accumulated within the first few years of teaching. School districts that try to equalize experience among all schools are overestimating its impact. There is no reason why a school with many teachers with only three or five years' experience cannot outperform a school with teachers who have an average of more than 10 years' experience.
For this reason, states need to report data that are more informative about a school's teachers. As more states require evaluation systems based primarily on teacher effectiveness (see Goal 3-B), the most important distribution data that state can make available is school-level data about teacher performance. This is not to say that individual teacher ratings should be reported, but school level data would shine an important light on whether all students have access to effective teachers.
In the absence of teacher performance data that reflects evidence of student learning, states can still provide meaningful information by using an index for quantifying important teacher credentials found to correlate with student achievement. A good example of a strong index is the academic capital index developed by the Illinois Education Research Council, incorporating teachers' average SAT or ACT scores; the percentage of teachers failing basic skills licensure test at least once; the percentage of teachers on emergency credentials; average selectivity of teachers' undergraduate colleges and the percentage of new teachers. These factors are complicated, so the state should install a system that translates them into something more easily understood, such as a color-coded matrix indicating a high or low score for a school.
States need to report data at the level of the individual school.
Only by achieving greater stability in the staffing of individual schools can districts achieve the nation's goal of more equitable distribution of teacher quality. A strong reporting system reflecting the index described above, as well as data on teacher attrition, teacher absenteeism and teacher credentials can lend much-needed transparency to those factors that contribute to staffing instability and inequity.
The lack of such data feeds a misconception that all high-poverty schools are similarly unable to retain staff because of their demographics. If collected and disaggregated to the level of the individual school, however, such data could shift the focus of districts and states toward the quality of leadership at the school level and away from the notion that instability and inequity are unavoidable consequences of poverty and race. Variations in staff stability are huge among schools with similar numbers of poor and/or minority children. School culture, largely determined by school leadership, contributes greatly to teacher morale, which in turn affects teacher success and student achievement. By revealing these variations among schools facing the same challenges, school leadership can be held accountable—and rewarded when successful.
Within-district comparisons are crucial in order to control for as many elements specific to a district as possible, such as a collective bargaining agreement (or the district's personnel policies) and the amount of resources.
Equitable Distribution: Supporting Research
For comprehensive review of the literature on teacher quality and distribution, see Jennifer King Rice, "The Impact of Teacher Experience: Examining the Evidence and Policy Implications", Calder Institute, August 2010, Brief 11. For more about how poor and minority children do not get their fair share of high-quality teachers, read L. Feng and T. Sass, "Teacher Quality and Teacher Mobility.", Calder Institute, Working Paper 57, January 2011; T. Sass, J. Hannaway, Z. Xu, D. Figlio, and L. Feng, "Value Added of Teachers in High-Poverty Schools and Lower-Poverty Schools," Calder Institute, Working Paper 52, November 2010; and Education Trust, Teaching Inequality: How Poor and Minority Students are Shortchanged on Teacher Quality (Washington, DC: Education Trust, June 6, 2006).
Education Trust also produced an analysis of the first set of state Equity Plans that pointed out the inadequacies of most states' data systems to produce reliable information about teacher qualifications and experience levels in schools disaggregated by poverty and racial composition of schools. Although almost all states were required to resubmit their plans and earned approval for them, many of the shortcomings of state data systems remained. For example, few states are equipped to identify by school, teachers' years of experience, meaning they cannot identify the ratio of new teachers to the full school staff. See Education Trust, Missing the Mark: States' Teacher Equity Plans Fall Short (Washington, DC: Education Trust, August 10, 2006).
