Our meta-analysis of 80 evaluations of Experience Based Career Education (EBCE) programs shows that EBCE works. Students not only scored significant gains in career, life attitude, and academic skills during their EBCE experience, but they also showed significantly greater gains in all three of those outcome areas than comparison students who received the regular high school curriculum. The positive statistical significance of the findings was so large that we developed a new index, called the "Basic Index of Strength" or the BIS, in order to discuss and compare differences in the strength of the findings.
