The purpose of this study was to examine the relationships between personality types and vocational choices in terms of educational technology undergraduates and postgraduates in China. A valid sample of 209 undergraduates and 194 postgraduates responded to the research instrument, including 8 items about vocational choices and the Personal Globe Inventory-Short which was employed to measure personality types. The important findings included: (1) the three-letter personality code of both educational technology undergraduates and postgraduates was identified as SAE (i.e., Social, Artistic and Enterprising), (2) significant differences were found between educational technology undergraduates and postgraduates in terms of several vocational choices, and undergraduates showed lower major persistence than postgraduates, (3) realistic personality type was found to be significant positive predictor of most of the vocational choices of educational technology undergraduates, (4) educational technology postgraduates who are interested in realistic activities showed little interests in educational technology, whereas the social personality type express much interests. Finally, several suggestions have been provided for undergraduates, postgraduates, academic advisor, and high school students who choose and intend to choose educational technology as academic major.
