This report lists and explains detailed guidelines for the preparation and transmittal of student transcripts by secondary schools. The guidelines were established by the Cooperative for School/College Communication Studies, a group composed of representatives of eight professional organizations representing college admissions officers, community and junior colleges, and secondary school administrators and guidance counselors. The guidelines are intended to lessen the problems caused by diversity in the kinds of information contained in transcripts, the form and sequence of transcript information, the physical structure of transcripts, and the form and definition of terms commonly used in transcripts. The guidelines identify five categories of information that should be included in all transcripts: student identification, school identification, general school information, student's academic history, and student's personal characteristics. Separate sections discuss each of these categories in detail, and recommendations are made for the reproduction, organization, and preparation of transcript materials for submission to college and junior college admissions offices.
