This guidebook is designed for use by teachers implementing a mentor-protege job-site visitation program to help vocational students, particularly nontraditional students, understand and gain more knowledge about selected vocational fields. The first section of the guide reports on the job site visitation program implemented in the Ysleta Independent School District in El Paso, Texas, during which the materials contained in this guide were developed. Included in the guide are the following materials: a project time line, sample letters and followup letters asking businesses to provide mentors for the program, a contact review form, sample confirmation and post-visitation thank-you letters, student and business interview forms, a student information and guide sheet, student self-evaluation and visitation evaluation worksheets, a parent permission slip, and a businessperson evaluation form. The guidebook also contains copies of the thank-you notes, site visitation forms, resumes, and job applications completed by students participating in the original site visitation program conducted in the Ysleta Independent School District.
