The third and fourth annual reports on law enforcement training in New Jersey ("Police Training: The Key to Professional Police Service," 1964-65 and 1965-66) review the powers, responsibilities, and duties of the Police Training Commission; law enforcement officers trained (including failures and total enrollments); hours of programed and other instruction; college courses and other supporting activities; instructional services; numbers of trainees from specific municipal, state, county, and other law enforcement agencies; hours of basic recruit training (by subjects); and school directors and county training coordinators. Subsequent reports ("Police Training: The Key to Professionalization," 1966-67 through 1968-69) cover basically the above information, together with such special programs as the Federally funded law enforcement training project at Jersey City State College, a scholarship program, and the Frederick A. Douglass Training and Education Program for blacks and Puerto Ricans. (Reports 1 and 2 are out of print at this time.) (LY)
