A study examined coordination between public vocational education and programs conducted under the Job Training Partnership Act (JTPA). The study entailed two years of extensive data collection at the state and local levels. In addition to the inherent structural barriers to coordination between vocational education and JTPA, the study uncovered other barriers to coordination that were related to potential threats to agencies' autonomy, resources, basic identity, and public image. Both JTPA and vocational education officials appeared to fear that serving too many hard-to-employ clients would weaken their credibility as effective job preparation agencies. The study also included many analyses attempting to construct a structural model of coordination. No significant relationships among the state and local variables could be found, however. Nor was it possible to combine the variables into a structural model with acceptable parameters. The data collected were, however, sufficient to formulate a set of tentative guidelines for initiating and improving coordination. It was determined that someone must take the lead in coordination, there must be mutual benefit for the cooperating parties, mutual accommodation is almost always necessary, and communication is the most important element in any coordination effort. (The appendix, entitled "Attempts at a Statistical Model of Coordination," includes a causal model, the survey instruments, information on structural equation modeling, and the results of testing the structural equation.)
