The Massachusetts Workforce Training Fund (WTF), funded by employer contribution (surcharge) of 0.075% of its unemployment insurance taxable wage base, provides training grants and technical assistance to organizations located in the state. The purposes of these activities are to impart or upgrade knowledge and skills of Massachusetts’ workers so that they and their employing firms can compete in the world economy. This study provided 10 case studies of firms who have received a training grant. The case studies combined qualitative and quantitative data analytical techniques to provide evidence about the net impact and return on investment of the training grant as well as the processes undertaken by the grantees to provide effective training.
