The Framework of Work Based Foundation Skills Project was undertaken to facilitate development of Pennsylvania's new workforce investment system Team PA CareerLink by identifying and developing common definitions of the foundation skills all workers need to function effectively in any workplace. A framework of 19 work-based foundation skills and knowledge with component subskills was developed through a comprehensive synthesis and comparison of state and national work-based foundation skills efforts. The skills identified included basic workplace skills, basic employability skills, and basic organizational knowledge (core knowledge about the nature of work and workplace organizations). The framework included links to assessment systems and instruments capable of measuring the foundation skills and links to Occupational Skills Standards to illustrate applications of skills in specific industry clusters. Once development of the unified framework is finalized, it will help practitioners accomplish the following things: design and implement competency-based curricula that are meaningful for workers; develop individualized education plans to meet learners' education and employment goals; link work-based curriculum, instruction, and assessment; reflect on current instructional and assessment practices and develop program improvement plans related to workplace education; and use a common framework and understanding of work-based foundation skills when working with new workforce investment system partners.
