This report presents the results of a four-year effort to develop a valid and reliable inservice needs assessment instrument. (The instrument was designed to identify competencies that should be the focus of inservice training for vocational educators who teach or provide services to special needs learners.) Chapter I is an introduction. Chapter II reviews new research on instruction and evaluation and describes how these issues have been included in the revised needs assessment survey. A description of the methodology/research design used in the development and field testing of the Special Needs Inservice Survey is provided in chapter III. This includes the survey's instrumentation, population, sampling plan, data collection methods, and data analysis techniques. Chapter IV presents data collected with the current version of the instrument. These data describe vocational educators' self-perceptions of their competencies in both general and specific instructional techniques related to special needs learners, as well as their preferences regarding the format, time, and delivery personnel needed for such inservice experiences. Chapter V reports the reliability and validity of the survey instrument. Chapter VI contains conclusions, a summary, and recommendations. A list of references precedes appendixes, including the instrument, sampling plan, and data tables. (YLB)
