This is a workshop simulation and interpretation guide designed for Title I teachers and district personnel. The participants should have some experience with the norm-referenced evaluation model. They learn to interpret normal curve equivalents (NCE) and NCE gains. Participants are led through an interpretive hierarchy from simple, descriptive interpretations of NCE gains to comparisons of results to other standards. The guide gives a brief introduction to exploratory/diagnostic and comprehensive interpretations. The simulation provides a complete evaluation report for a Title I project. A presenter's guide provides detailed information for the workshop leader. Specific objectives for participants include description of meaning of NCE gain, conversion to a percentile change, construction of confidence bands around gains and use of them to guide interpretations. Other areas are identification of comparisons for NCE gains, determination of gain difference from a standard determination of whether a project needs more thorough investigation and where to focus it, and identification of areas to gather information.
