Abstract
Federal loan forgiveness programs for teachers are an underutilized resource for recruiting and retaining teachers in high-need schools. Increasing awareness and participation in these programs can be an effective strategy to improve teacher quality in high-poverty public schools in Michigan. We intend to contact 11,000 teachers in Michigan with information about the Teacher Loan Forgiveness program (TLF) and their eligibility. We want to know if providing eligible teachers with clear, timely information about TLF and/or support in submitting applications will: (a) increase the fraction of eligible teachers who apply for and obtain TLF; and (b) increase teacher retention in high-needs public schools in Michigan.

Experimental Design

Experimental Design
We decided on a two-pronged information treatment. We first sent each teacher in the treatment group a letter, addressed to them personally at their school address. The letter included: (a) a generic cover letter from MDE, (b) a sheet showing the teacher's personal eligibility status based on the MDE data we analyzed, which also listed various resources for the teacher regarding TLF, (c) a color brochure highlighting key pieces of information about TLF in a simple, transparent and eye-catching way, and (d) a link to a Frequency Asked Questions (FAQ) document.
Experimental Design Details
Randomization Method
Randomization for both school and individual-level treatments were done in Stata with seeds set by a true random number generator
Randomization Unit
School; individual
Was the treatment clustered?
Yes
