Retaining Effective Teachers Policy
The state should give local districts authority over pay scales.
Indiana requires local salary scales to be based on a combination of factors. Years of teacher experience and content-area degrees beyond the requirements for employment may not account for more than 33 percent of the calculation. The remaining calculation is based on results of the teacher evaluation.
Indiana Code 20-28-9-1
Indiana 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 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. As discussed in the rationale for Goal 3-E, 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.
Pay Scales: Supporting Research
For evidence that degree status does not increase teacher effectiveness and should therefore not be automatically rewarded in teacher salary schedules, see the following:
