Apprenticeship is a learning model and a proven strategy for (1) developing a talented and trained pipeline of workers for employers; and (2) expanding family supporting careers for individuals not pursuing a traditional four-year college track (without foreclosing their opportunities to pursue college down the road). Yet in Pennsylvania, as in states across the United States (U.S.), apprenticeship has been underutilized. In Spring 2016, Pennsylvania established the Apprenticeship and Training Office (ATO) within the Pennsylvania Department of Labor and Industry (L&I). ATO established a strategic partnership with Keystone Development Partnership (KDP), a labor-management partnership with extensive experience building Industry (training) Partnerships, to expand the state's outreach capacity to employers and unions about apprenticeship The ATO also began engaging and sharing information with workforce boards across the state, elevating apprenticeships as a central Pennsylvania workforce development strategy and a key tool for expanding "employer driven" training. Since 2017, Pennsylvania has invested in expanding and assisting apprenticeship and pre-apprenticeship programs through grants from L&I (e.g., through the new PAsmart initiative) and through the Department of Community and Economic Development (DCED). This report sketches the major challenges to the expansion of apprenticeships and the benefits of apprenticeships--which make the challenges worth overcoming. The second half of the report outlines 10 actions the ATO and Pennsylvania state government could take to grow apprenticeships and capture its benefits at a larger scale.
