The purpose of this study is to estimate costs and benefits and to compute alternative benefit-cost ratios for both the individuals and the Federal Government as a result of investing time and resources in the Training and Technology (TAT) Project. TAT is a continuing experimental program in training skilled workers for private industry. The five occupational areas included in the study are mechanical drafting, welding, machining, industrial electronics, and physical testing-quality control. Data were obtained by analyzing two samples of 70 persons each; one sample selected from 407 TAT trainees, the other sample from 1,500 qualified applicants not admitted because of limited space. The methodology, the cost of training to the Federal Government, the expected value of income differences between the trained and control groups by year, the expected value of tax differences accruing to the Federal Government by year, and the computation of the number of deductions per pay check are appended.
