The purpose of this study was to develop and establish the validity and reliability of an instrument to measure students' attitudes toward geometry. Participants consisted of 264 undergraduate students from two universities, one in the Midwest and one in the Southwest. The instrument is a 5‐point Likert‐scaled survey consisting of 32 statements and 3 subscales. The internal consistency using Cronbach's coefficient alpha was 0.95 for the confidence subscale, 0.93 for the usefulness subscale, and 0.92 for the enjoyment subscale. For the overall instrument using the 32 items that comprised the three subscales, internal consistency reliability analysis revealed a Cronbach's coefficient alpha of 0.96. Additionally, this article reports on the content, criterion, and construct validity of the instrument.
