In this evaluation, as in previous years, four main aspects of the implementation of the West Virginia Board of Education's Master Plan for Statewide Professional Development were examined: (a) basic information reported by providers about the size and scope of the effort, including attendance, and adherence to the newly adopted standards for professional development; and participant reports (gathered through the administration of a randomized statewide survey) about the (b) quality of the sessions, (c) their alignment to Board goals for professional development, and (d) the impacts of the sessions on participants' knowledge, practice, and attitudes and beliefs. Each of these four areas is discussed herein, including trends noted over the three years that the WVDE Office of Assessment, Accountability, and Research has conducted this evaluation. An appendix contains additional tables.
