The development of a needs instrument designed to assess the continuing education needs of school administrators is described. The instrument was constructed to assess the administrators' continuing needs in: (1) principalship; (2) the school as a system; (3) problem solving; (4) staff development; (5) collaborative long-range planning; (6) short-term planning; and (7) personal awareness. Thirty-eight questions for the assessment were written using a standard domain sampling model, and the revised questions were made into a questionnaire using a Likert discrepancy model. Respondents rated statements on a five-point scale of perception of the degree to which the situation actually exists and perception of the extent to which it is desired to exist. The discrepancy between the two scale values is referred to as the need index. Content validity was established through factor analysis with a sample of 191 school administrators. Reliability measures indicate that the instrument can be used for group assessment. Items for the survey are listed, and two tables present the varimax rotated factor matrix for the two instrument columns (Contains 34 references.) (SLD)
