This project has been a collaborative effort between the Institute on Education and the Economy at Teachers College and RAND Corporation. We want to thank Cathy Stasz, who directed the work at RAND, and Melissa Bradley, who oversaw the survey. We also received useful comments and suggestions from Nevzer Stacey. The project would not have been possible without the cooperation and assistance of the educators and program organizers who helped us understand their work and made it possible for us to interview the employers who provided internships.
