Based on a program developed in Oregon, this guide provides information on creating and maintaining a program to link schools and businesses in order to allow teachers to have summer assistanceships. The guide covers the need for such a program, its purpose and desired outcomes, potential organizational structures, managing the program, funding program management, teacher compensation, graduate credit, summary of commitments to the program, program evaluation, and maintaining the program. Twenty appendixes describe the Workforce 2000 Educator Internship Program that is the basis for the guide; they include the documents used in that program, such as letters, flyers, workshop guides, job application forms, evaluation survey forms, graduate seminar and practicum outlines, employer-school agreements, and surveys of participants.
