By 2050, the number of Americans needing long-term care services and supports will double. They will have more acute and complex care needs than previous generations, and they will be more likely to receive care at home or in a residential setting than in an institution. These factors are driving the increased demand for workers providing home care services and for better training. One of the biggest workforce challenges we face as a country is how to meet the growing demands for such a critical workforce. One model has emerged in Washington State: The SEIU Healthcare NW Training Partnership. Founded in 2007, this nonprofit school is the nation’s largest training provider for workers in home care. The Training Partnership has created a statewide training system with comprehensive resources and tools to support home care workers, consumers and employers. This case study provides an overview of the Training Partnership and its history, offerings—-including the nation’s first Registered Apprenticeship program for home care workers—-and outcomes. It also summarizes the model’s strengths and challenges. The development of this case study was generously supported by SkillUp Washington and the Ford Foundation.
