Differential Pay: Iowa
Retaining Effective Teachers Policy
Analysis of Iowa's policies
Iowa does not support differential pay by which a teacher can earn compensation by teaching certain subjects. However, the state has no regulatory language preventing districts from providing such differential pay.
Nevertheless, in an effort to "provide supplemental assistance to the highest-need schools in Iowa," the state provides state assistance to allow school districts to "supplement the salary of teachers in the identified [high-need] schools."
Recommendations for Iowa
Support
differential pay initiatives for effective teachers in both subject-shortage
areas and high-need schools.
Iowa should encourage districts to link compensation to
district needs. Such policies can help districts achieve a more equitable
distribution of teachers. Although the state is making an effort to compensate teachers in high-need schools, the requirement is vague. With greater specificity, this differential pay could be an incentive to attract some of Iowa's most effective teachers to low-performing schools.
State response to our analysis

Research rationale
States should help
address chronic shortages and needs.
States should ensure that
state-level policies (such as a uniform salary schedule) do not interfere with
districts' flexibility in compensating teachers in ways that best meet their
individual needs and resources. However, when it comes to addressing chronic
shortages, states should do more than simply get out of the way. They should
provide direct support for differential pay for effective teaching in shortage
subject areas and high-need schools. Attracting effective and qualified
teachers to high-need schools or filling vacancies in hard-to-staff subjects
are problems that are frequently beyond a district's ability to solve. States
that provide direct support for differential pay in these areas are taking an
important step in promoting the equitable distribution of quality teachers.
Short of providing direct support, states can also use policy levers to
indicate to districts that differential pay is not only permissible but
necessary.
Differential Pay: Supporting Research
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 Institute, Working Paper 57, January 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 http://www.urban.org/UploadedPDF/1001469-calder-working-paper-52.pdf.

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. Kirby, M. Berends, and S. Naftel, "Supply and Demand of Minority Teachers in Texas: Problems and
