A project involving the cooperative effort of the Ling-Temco-Vought Corporation and governmental agencies relocated 684 South Texans to metropolitan areas for work as aircraft assemblers after a four-week training program in the Lower Rio Grande Valley. About 90% of these relocatees were Mexican Americans. Sixteen months after the first families were relocated and four months after the last families were relocated there were 75.58% of the trainees still on the job. The purpose of this project was to study the adjustment which takes place as a result of retraining and relocation, and to determine what sociological factors represented the best predictors for success in the program including retention after retraining. Education level and previous occupation proved to be the best predictors of success in the program. The major conclusion drawn from the study was that selected external factors are usable as predictors of ability to retrain and relocate, but conclusions based on a priori conditions are at best tentative.
