This publication highlights a business value assessment of a work-based learning project (WBL) conducted at Temple University Hospital-Episcopal Campus. The training, designed and delivered by District 1199C Training and Upgrading Fund in partnership with the University of Medicine and Dentistry of New Jersey, provided training to 21 mental health workers at the hospital from 2008 to 2009. In this paper, WSI describes the training model and discusses the value of the training to the hospital and employees. Research was based on qualitative and quantitative data collected before, during, and after the WBL project was implemented. The publication also highlights the business value assessment research methodology and the challenges and opportunities addressed in carrying out this type of evaluation. Both the work-based learning program and this research were funded through Jobs to Careers: Promoting Work-Based Learning for Quality Care. Jobs to Careers is an initiative of the Robert Wood Johnson Foundation, in collaboration with The Hitachi Foundation and U.S. Department of Labor.
