Differential Pay: Iowa
Retaining Effective Teachers Policy
Analysis of Iowa's policies
Iowa no longer supports differential pay by which a teacher can earn additional compensation by teaching certain subjects.
Iowa does not support differential pay for those teaching in high-needs schools, even though the state does not have regulatory language that would directly block districts from providing differential pay.
Recommendations for Iowa
Support differential pay initiatives for effective teachers in both subject shortage areas and high-needs schools.
Iowa should encourage districts to link compensation to district needs. Such policies can help districts achieve a more equitable distribution of teachers.

Research rationale
Two recent studies emphasize the need for differential pay. In "Teacher Quality and Teacher Mobility", L. Feng and T. Sass find that high performing teachers tend to transfer to schools with a large proportion of other high performing teachers and students, while low performing teachers cluster in bottom quartile schools (CALDER: Urban Institute 2011). Another study from T. Sass et al found that the least effective teachers in high-poverty schools were considerably less effective than the least effective teachers in low-poverty schools.

A study by researchers at Rand found that higher pay lowered attrition, and the effect was stronger in high-needs school districts. Every $1,000 increase was estimated to decrease attrition by more than 6 percent. See S.N.
