The purpose of this study was to assess the effects of a 9-week career intervention program on at-risk middle school students' career maturity levels, self-esteem, and academic achievement. This study was based on a pretest and posttest design using a control group. Data were collected from 27 at-risk middle school students representing the experimental group and 30 at-risk middle school students making up the control group. Modes of measurement consisted of the Crites Career Maturity Inventory (measuring attitude and competency levels), the Coopersmith Self-Esteem Inventory, and grades. Data for this study were coded numerically and analyzed using inferential t tests and analysis of covariance. Qualitative interviews were conducted with teachers of 5 randomly selected participants from the experimental group to compare self-esteem and academic achievement prior and subsequent to the treatment. Although results revealed that the sample's career maturity attitude and competency levels and academic achievement improved, such increases were not statistically significant. Recommendations for future research and implications for school counselors are discussed.
