Summary The preliminary development of a personality test, the Zax Information Profile (ZIP), involving 24 content areas was described. Measures of internal consistency of the items in the separate sub-tests are reported as well-as the factor structure of the test with reference to several different S samples. Although internal consistency measures are not as high as were hoped for, they are consistent with similar measures done on somewhat similar test instruments. Furthermore, an external validation study demonstrated that the test differentiated very effectively between music students and arts college students in the predicted directions. The potential use of the test as a screening device for entering college students, and as an instrument for providing leads for constructing optimal housing arrangements and programs to prevent social maladjustment in college students was discussed.
