The Counterfactual: Prevailing Induction Services

We designed the study to compare teachers who were exposed to comprehensive teacher induction services (treatment) to an equivalent group that was exposed to the induction services normally offered by the districts (control). We purposefully selected districts whose schools were not already working with ETS or NTC on induction projects, were not using the providers' induction materials, were not spending more than $1,000 per teacher on induction, and did not assign full-time release mentors to work with beginning teachers.
