This directory is intended for general information and guidance for educators in penal institutions. In compiling the directory, questionnaires were sent to 364 state and 28 federal penal institutions in the United States. Responses were received from 257 state institutions comprising all 50 states and from all 28 federal institutions. It has been assumed that 107 state institutions which did not respond have no vocational training programs. These 107 institutions are for the most part small camps. farms or centers with less than 100 population. The institutions that reported and are listed account for over 225,000 of the 230,000 inmate population in the United States. It is therefore felt that the institutions listed represent nearly all those offering vocational training. The directory is presented in three sections: Part One, Listing of Institutions Comprising Directory, Part Two, Institutions Offering Training by Vocational Area, and Part Three, Vocational Training Offered by Individual Institutions. A study of the relationship between these programs and the unfilled job openings in the major occupations of the United States is available as ED 025 598. (CH)
