The Teacher Comments study is available in a machine-readable data file that is part of the High School and Beyond (HSB) Class of 1980 Survey, administered in 1980 to a national sample of over 30,000 sophomores and 28,000 seniors from 1,015 high schools in the United States. This file contains data in two subfiles: (1) the sophomore teachers' file, containing responses of 14,103 teachers about 18,291 students in the sample from 616 schools; and (2) the senior teachers' file, with responses from 13,683 teachers about 17,056 students in the sample from 611 schools. Teachers responded to mailed questionnaires about the students they taught during the 1979-80 school year. The typical student was rated by an average of four teachers. Seven topics were common to both sophomore and senior questionnaires: (1) college probability; (2) academic potential; (3) popularity; (4) individual counseling about school; (5) interest in school; (6) self-discipline; and (7) physical or emotional handicaps. The sophomore file recorded subjects taught, class time used to keep order, and sex and race of the teachers. The two files contain 76,500 observations of sophomores and 67,053 observations of seniors, respectively. TYPE OF SURVEY: National Survey; Sample Survey.
