The authors investigated the influence of a 9-week career education class o
n career decision-making self-efficacy, vocational skills self-efficacy, pe
rceived educational barriers, outcome expectations, educational plans, and
career expectations among a sample of 166 high school sophomores. Using a n
onrandomized, within-subjects crossover design, the authors collected prete
st, posttest, and follow-up data with a health education class as the contr
ol condition. Post- and follow-up testing suggest that the class resulted i
n increased career decision-making self-efficacy, vocational skills self-ef
ficacy, and short-term gains in outcome expectations but did not influence
perceived educational barriers. Participants enrolled in the career educati
on class in the first quarter were more likely to change career plans than
were those in the control condition. Implications for practice and future r
esearch are presented.
