Prior work suggests that recent graduates from teacher education programs feel better prepared to teach and are more instructionally effective when they learned to teach with more instructionally effective cooperating teachers. However, we do not know if these relationships are causal. Even if they are, we do not know if it is possible to recruit cooperating teachers who are, on average, significantly more effective than those currently serving. This paper describes an innovative strategy to use historical administrative on teachers to recommend the most instructionally effective and experienced teachers in various districts and subject areas to serve as cooperating teachers. In collaboration with a large teacher education program, partnering districts were randomized to receive either recommendation lists or use business-as-usual approaches. Those districts that received recommendations recruited significantly and meaningfully more effective and experienced cooperating teachers. Additionally, preservice student teachers who learned to teach in these same districts felt significantly better prepared to teach. This study offers an innovative and low-cost strategy for recruiting effective and experienced cooperating teachers and presents some of the first evidence that learning to teach with instructionally effective cooperating teachers has a causal impact on feelings of preparedness to teach.

Growing evidence suggests that preservice candidates receive better coaching and are more instructionally effective when they are mentored by more instructionally effective cooperating teachers (CTs). Yet, teacher education program leaders indicate it can be difficult to recruit instructionally effective teachers to serve as CTs, in part because teachers worry that serving may negatively impact district evaluation scores. Using a unique dataset on over 4,500 CTs, we compare evaluation scores during years these teachers served as CTs to years they did not. In years they served as CTs, teachers had significantly better observation ratings and somewhat better achievement gains, though not always at significant levels. These results suggest that concerns over lowered evaluations should not prevent teachers from serving as CTs.
