A study examined the acceptance of the time-shortened articulation (TSA) approach adopted to implement tech prep programs by Idaho postsecondary trade and industrial instructors. From a sample of 143 instructors, 46 usable responses were received. Hall's (1979) Stages of Concern (SoC) model was used to determine if they had accepted the process, attitude, and goal of TSA tech prep. Responses were analyzed to determine to which of Hall's seven SoC levels the instructors had progressed. The SoCQ Scoring Device was used to score the questionnaires. Individual raw scores were computed, converted to SoC intensity percentiles, and individually graphed. Individual graphs were examined to assess the peak SoC stage and thus indicate where each instructor was on the acceptance continuum. Scores were then grouped by demographic data: instructor's educational institution, age, trade and industrial subject area, and educational level. The SoC profiles indicated that only 6 instructors or 13 percent had accepted TSA tech prep. Certain groups did not accept this educational change: instructors with graduate degrees, welding instructors, and instructors from certain institutions. No significant difference among the groups studied was indicated by a chi-square treatment. (Appendixes include 6 tables and a list of 10 references.) (YLB)
