Public funding for employment and training has dwindled over the past several decades. Yet in communities all over the United States, there has been considerable development of alternative approaches to help low-income people gain skills for particular industry sectors. In 2003, with support from the Charles Stewart Mott Foundation, P/PV launched the Sectoral Employment Impact Study to test the efficacy of one such approach. Using a random-assignment design, P/PV researchers set out to answer the question: Can well-implemented, sector-focused training programs make a difference to the earnings of low-income disadvantaged workers and job seekers? Three organizations were selected to participate in the study: Jewish Vocational Service in Boston, Per Scholas in the Bronx and the Wisconsin Regional Training Partnership in Milwaukee. This issue of P/PV In Brief summarizes impacts found for participants across the three sites, including increases in earnings and employment; a more detailed report on the study will be released in late 2009.
