As the national documentary unit of American Public Media, American Radio Works' riveting hour-long documentaries are broadcast on public radio stations throughout the United States, and across the Internet. Listeners who miss their broadcast on local stations can go to the American Radio Works website to listen to their new and archived documentaries. The documentary "Testing Teachers", which is about quality testing public school teachers, is one that sparks much debate among teachers, students, parents, the public, and policy makers. Five questions are asked in the documentary including: "What is Good Teaching?"; "Are Test Scores the Right Measuring Stick for Teachers?"; and "Do Poor Kids need Different Kinds of Teachers?". Visitors are also given the opportunity to write about their best teachers, as well as read responses to that same query from public radio listeners in the Minnesota and Wisconsin area, where the documentary was produced and first broadcast.
