The report describes the first few months of operation of an experimental Work Incentive Program (WIN) in Portland, Oregon to test the feasibility of the use of vouchers for on-the-job training (OJT). Voucher holders were required to decide on a training occupation, and then locate and negotiate for an employer to provide the training. WIN staff members served as information resources, wrote OJT contracts, and monitored vouchered training progress. The 265 vouchered clients did not differ markedly from the WIN clientele as a whole. Over several months the proportion taking vouchers dropped from 45% to 38% of those eligible. Fewer than a fourth of the vouchers were converted into OJT contracts. Voucher holders who were morehighly educated, younger, female, or voluntary WIN participants were relatively more successful in committing the voucher to an employer. Compared with regular OJT people, vouchered people held slightly higher level jobs, earned slightly higher wages, and trained for somewhat longer periods of time. Among the 166 people who were unable to commit their vouchers within the six weeks alloted, several went into regular OJT positions, some returned to school or were terminated from WIN, and many were on regular WIN job searches.
