This monograph, structured for administrative use in analyzing and building systems for selecting teachers, outlines the legal, applied, and theoretical issues of teacher selection. This overview is presented in five sections. "Legal Aspects of Teacher Selection" examines individual rights and employer reactions in relation to federal and state legislation. In general, under federal acts, applicants must show only prima facie evidence of discrimination in the selection process. Section 2, "Applied Aspects of Teacher Selection," analyzes predictors used by administrators to select teachers. A static decision strategy is based on a compensatory model for selection, whereas a sequential decision strategy is based on a multiple-cutoff model. Section 3, "Theoretical Aspects of Teacher Selection," considers research approaches. Research involving applicants' selections is theory-based, whereas research involving organizations' selections is empirically based. Macroanalytic research assesses the relationship between a performance measure and a performance predictor. Microanalytic research approaches the decision-making process within the selection context and identifies variables unrelated to teaching performance but which influence selection. In conclusion, administrators and boards must formalize and evaluate their selection systems. A research thrust should include individual and organizational aspects. Administrators and researchers must work jointly on teacher selection; field studies are recommended. Fifty-seven references are appended. (CJH)
