The study involving 149 National Technical Institute for the Deaf summer orientation program students evaluated the use of the Career Maturity Inventory-Attitude Scale (CMI) with a deaf college student population. The original form of the test and an adapted version were used with two groups of students who were tested three times during a 2 1/2 year period. Results showed that the adapted version of the CMI is more feasible than the original form for use with a deaf population. A high correlation was found between language ability and mature career attitudes. A finding not anticipated was that students in the upper quartile changed their college majors more often than students in the lower quartile. Implications for the use of the instrument are discussed. (SB)
