Retaining Effective Teachers Policy
While giving local districts authority over pay scales, the state should ensure that effectiveness is a factor in teachers' compensation.
Colorado does not articulate an adequate compensation policy that rewards effective teachers.
Colorado gives local districts the authority to set pay scales, eliminating barriers such as state salary schedules that control how districts pay teachers. The state allows districts the option of adopting a salary schedule based on job description and definition, a salary policy "based on level of performance demonstrated by each teacher," or a combination of salary schedule and salary policy. Colorado requires that if a district adopts a salary schedule, it must place each teacher "at a level at least commensurate with, but not limited to, each teacher's education, prior experience, and experience in the district as provided in the salary schedule."
However, while leaving decision making about pay scales in district hands, the state should ensure that the factors in local salary schedules reward effective teachers. Colorado has no requirement that districts include teacher performance or exclude factors not associated with teacher effectiveness, such as advanced degrees. On the contrary, the state requires that teachers' education levels be a factor in determining pay should a district adopt a salary schedule.
Beyond local pay scale requirements, Colorado does not have any policies in place that offer teachers additional compensation based on evidence of effectiveness.
Colorado Revised Statutes 22-63-401
Discourage districts from tying compensation to advanced degrees and/or experience.
Rather than the state's existing policy, which requires districts that adopt salary schedules to connect pay to education, Colorado should still leave districts the flexibility to establish their own pay scale. The state should also articulate policies that definitively discourage districts from tying compensation to advanced degrees, in light of the extensive research showing that such degrees do not have an impact on teacher effectiveness. Similarly, Colorado should articulate policies that discourage districts from determining the highest steps on the pay scale solely by seniority.
Support a performance pay plan that recognizes teachers for their effectiveness.
Whether it implements the plan at the state or local level, Colorado should ensure that performance pay structures thoughtfully measure classroom performance and connect student achievement to teacher effectiveness. Districts should be given the flexibility to define the criteria for performance pay provided that such criteria connect to objective evidence of student achievement. The plan must be developed with careful consideration of available data and subsequent issues of fairness, and it should allow for the participation of all teachers, not just those in tested grades and subjects.
Colorado recognized the factual accuracy of this analysis.
Compensation reform can be accomplished within the context of local control.
Teacher pay is, and should be, largely a local issue. Districts should not face state-imposed regulatory obstacles that prevent them from paying their teachers as they see fit; different communities have different resources, needs and priorities. States should remove any barriers to districts' autonomy in deciding the terms for teacher compensation packages.
The state can ensure that all teachers are treated fairly by determining a minimum starting salary for all teachers. However, a state-mandated salary schedule that locks in pay increases or requires uniform pay deprives districts of the ability to be flexible and responsive to supply-and-demand problems that may occur.
While leaving districts flexibility to decide their own pay scales, states should promote compensation tied to teacher effectiveness and discourage districts from basing pay solely on criteria not correlated with teacher effectiveness.
Across the country, state and district salary schedules are based primarily on just two criteria: advanced degrees and years of experience, neither of which is correlated with teacher effectiveness. The impact of advanced degrees on teacher performance has been studied extensively, and research has shown that such degrees generally do not make teachers more effective. Years of experience do have an impact on teacher effectiveness very early in a teacher's career, but this effect is gone after the first few years of teaching. Because of their predominance in current salary schedules, states need to take a proactive role in preventing districts from basing teacher pay primarily on these two criteria.
Performance pay is an important recruitment and retention strategy.
Performance pay provides an opportunity to reward those teachers who consistently achieve positive results from their students. The traditional salary schedule used by most districts pays all teachers with the same inputs (i.e., experience and degree status) the same amount regardless of outcomes. Not only is following a mandated schedule inconsistent with most other professions, it may also deter talented individuals from considering a teaching career, as well as high-achieving teachers from staying in the field, because it offers no opportunity for financial reward for success.
States should set guidelines for districts to ensure that plans are fair and sound.
Performance pay plans are not easy to implement well. There are numerous examples of both state and district initiatives that have been undone by poor planning and administration. The methodology that allows for the measurement of teachers' contributions to student achievement is still developing, and evaluation systems based on teacher performance are new in many states. Performance pay programs must recognize these limitations. There are also inherent issues of fairness that should be considered when different types of data must be used to assess the performance of different kinds of teachers.
States can play an important role in supporting performance pay by setting guidelines (whether for a state-level program or for districts' own initiatives) that recognize the challenges in implementing a program well. A few states now require that districts build performance into salary schedules, moving away from bonus structures that teachers know may be subject to budget constraints and competing priorities.

Research on merit pay in 28 industrialized countries from Harvard's Program on Education Policy and Governance found that students in countries with merit pay policies in place were performing at a level approximately one year's worth of schooling higher on international math and science tests than students in countries without such policies (2011).
Erik Hanushek found that a teacher one standard deviation above the mean effectiveness annually generates $400,000 in student future earnings for a class size of 20. See E. Hanushek, "The Economic Value of Higher Teacher Quality," National Bureau of Economic Research, Working Paper 16606, December 2010.
In addition, numerous conference papers published by the National Center on Performance Incentives reinforce the need to recognize the limitations and appropriate uses of performance pay. See: http://www.performanceincentives.org/.
