The Program Standards Evaluation System was developed in response to evaluation requirements in the 1973 Rehabilitation Act. The system includes procedures for using standards data to monitor and evaluate vocational rehabilitation (VR) service outcomes and outputs as well as standards on key procedural issues. This report, which is Appendix A of the analytic paradigm for management use of the Program Standards Evaluation System, contains decision trees and displays for the data elements of the revised performance standards. The report is organized as follows: (1) decision trees are summarized in table format, indicating several possible explanatory scenarios for problematic performance on the data element; and (2) displays are keyed to each table, providing interpretation at various steps in the decision process and directing the analyst to the data elements. Most displays include a summary of the problem as defined by the relevant stage of investigation, including tests to use and norms for each data item. The tables, one for each element, show how the problem flagged by a particular element can be broken down into more specific subproblems by looking at other data items; table numbers correspond to the number of the data element in the standards system, and each table includes two or more possible scenarios that might explain problematic performance on the data element. Other displays show the logical steps summarized in the tables in more detail, introduce tests on other data elements, and compare the values of these elements with agency norms to analyze the display problem. In addition to the data-element-related tables, two special displays describe particular situations. (KC)
