The purpose of this study was to develop a valid and reliable preference indicator that practitioners could use to identify the Multiple Intelligences of adult learners. This tool was designed for use in instrumented-learning situations rather than for psychological testing in clinical settings. This preference indicator was constructed by compiling a pool of items congruent with Gardner''s (1983) concept of MI and by doing multiple rounds of filed testing and data analysis to reduce this pool to a useable set of valid and reliable items. As part of this process, the survey based on these items was given to a large number of community college students, and their responses were used to confirm the final form of an indicator to identify MI preferences.
