This addendum to the original study presents expectancy tables for 28 civilian vocational-technical courses in which 5,211 students were enrolled in 25 high schools situated in the northeast, midwest and far west regions of the country. Also included in this note is a suggested ASVAB interpretative guide. School samples were obtained through voluntary participation. The investigators are indebted to all participating counselors, administrative personnel, principals, and students.
