This study was conducted to investigate the relationship of specified variables on the opinions held by selected Oklahoma high school personnel about the junior college and to compare their opinions to those of counselors in two other states where similar studies have been conducted. A questionnaire was sent to 583 persons; one instrument was sent to each public high school and vocational-technical school in Oklahoma, with the exception of 23 large high schools to which one instrument was sent for each counselor with senior class counseling responsibilities. A total of 429 (74 percent) responded. Results indicate that those most favorably disposed to junior colleges were those who had attended a junior college, those whose high schools were visited regularly by junior college personnel, or those who had visited junior colleges attended by their graduates. The opinions of Oklahoma teachers, counselors, and administrators were different than those of the counselors in Texas and Illinois. The study found no differences in opinion on the bases of sex, position in the high school, coursework in vocational guidance, coursework focusing on the junior college, type of college nearest the high school, full-time employment outside the field of education, occupational teaching background, size of high school graduating class, geographic proximity to specific junior colleges, or college or university last attended.
