Pennsylvania has three regional Professional Personnel Development Centers responsible for the delivery of services around a block of common objectives designed to meet the professional development needs of vocational educators. The Developing a Curriculum (DACUM) process has been used to address two areas of need identified by the Temple University Center for Vocational Education Professional Personnel Development: the roles of the Workplace Learning Teacher Coordinator (WLTC) and the Teacher Leader. The center has developed a definition for the WLTC and a DACUM chart. This chart of 10 duty categories with 125 task items has been converted to a survey and validated on three dimensions: level of importance, degree of difficulty, and frequency of occurrence. The DACUM chart is currently being applied as a standard to revise the Cooperative Vocational Education Teacher Coordinators Certification Program at Temple University (Philadelphia). A second DACUM process has been used to satisfy two concerns: a clearer definition of the mission and purpose of the role of lead teachers and a more formal method of acquiring graduate credit in this area of leadership. A survey has been used to validate the DACUM chart according to three criteria used in the survey. The DACUM process has led to development of the Teacher Leadership Network, Teacher Leadership Master's Degree, and Teacher Leadership Certificate. (Half of the document consists of appendixes containing WLTC validation instrument and mean ratings and WLTC and Lead Teacher DACUM charts.) (YLB)
