The field of youth development is expanding, requiring 4-H Extension staff to gain expertise in the field without leaving their jobs to return to school. To address this need, the 4-H Youth Development Practitioner Apprenticeship (YDPA) program was developed under the guidance of the National Association of Extension 4-H Agents and the National 4-H Council through funding from the U. S. Department of Labor. An evaluation of the pilot of YDPA found that staff gained numerous skills needed to effectively serve youth. Suggestions for program continuation are discussed
