The present study investigates how parental influence, career maturity, and self efficacy affect perceptions of postsecondary outcomes among deaf or hard-of-hearing students. Research suggests that deaf or hard-of-hearing students graduate from high school with the equivalent of a 4th or 5th grade reading level. Subsequently, this population of students will ultimately be affected in areas such as educational & career attainment, employment, and overall quality of life. Fifty-three deaf or hard-of-hearing students (28 females and 25 males) were surveyed to determine if differences exist between these factors when compared to normative data. One sample t-tests were conducted to determine if significant differences existed between this particular population of students and the normative data from each instrument selected respectively. Results were supportive of significant differences between deaf or hard-of-hearing students and the normative data on factors related to career related parental support, career decision-making, and career decision self-efficacy.
