This study tested the validity and reliability of a survey instrument designed to measure students' perceptions of teacher's power and students' affinity for a teacher. Respondents were 30 students enrolled in two basic communication courses at a midsize public university. The researcher distributed a survey that contained measures of affinity and power. Respondents took the survey home and returned it the following class period. The survey included three sections that examined students' perception of teacher power, students' affinity for the teacher, and demographics. Data analysis indicated that students' affinity for the teacher related to their perception of the teacher's power. Based on the statistics, the study indicated that the survey instrument was readable and useful. Because the pilot study found the survey usable, a sample size was calculated for use in a formal study to gather norming data for the instrument. In an effort to obtain norming data for the instrument, the survey would be administered to students taking a core course at several different colleges. The summary instrument is included.
