These two reports describe the research, analysis, and results of the second phase of a three-phase research study sponsored by the Standards and Training for Corrections Program (STC) of the California Board of Corrections. The validation report consists of seven chapters. Following an introductory chapter that explains the rationale for the program and documents the approach, the remainder of the report describes the methods used to develop and validate entry-level selection procedures, especially for juvenile counselors. Chapter 2 summarizes the job analysis results that formed the foundation for predictor and criterion development. Development of the predictors and criteria are described in Chapters 3 and 4. Chapter 5 describes the methods used to collect predictor and criterion data from a sample of approximately 200 juvenile counselor incumbents and their supervisors. Chapter 6 reports the methods used to analyze the predictor and criterion data and documents the results of those analyses. Finally, Chapter 7 reviews the results with an eye toward their interpretation and the implications they have for use of the Juvenile Counselor examination as part of the preemployment selection process of participating agencies. The technical adequacy report examines the criterion data collection and the adequacy of the sample to confirm the technical adequacy of the research described in the validation report. (KC)
