Reasons for the long-range success of the Los Angeles Community College District's evaluation system for its handicap program are explored in this report, using a force field analysis of facilitating and restraining factors. First, introductory material cites previous reports exploring various aspects of the evaluation system. Next, the following five major predisposing factors are analyzed as reasons for the success of the evaluation system: (1) the program's evaluation system was seen as "invented here by us, the major players," i.e., by the district administrator and each of the nine campus coordinators; (2) there was an adequate level of trust between all the major players; (3) there existed at least three supportive organizational factors (i.e., special funding that required accountability, a manageable span of control, and line authority on the part of the 10 program managers); (4) the nine different forms of resistance to innovation were overcome; and (5) there was a readiness for innovation. Each of these factors is discussed in terms of the results of the force field analysis and with reference to relevant literature on the implementation of innovations in general and program evaluations in particular. Appendices provide additional material on the force field analysis, the comprehensive evaluation services within the district, an outline of conditions related to readiness for change by cluster, and a three-page bibliography.
