Evaluating the Validity of Educational Rating Data.
Harwell, Michael
Educational and Psychological Measurement, v59 n1 p25-37 Feb 1999
Suggests two complementary frameworks for providing validity evidence for rating data. One conceptualizes raters as data collection instruments that should be subject to traditional procedures for establishing validity evidence; the other evaluates studies using raters from an experimental design perspective allowing the assessment of the study's internal validity. Both approaches are illustrated. Contains 35 references. (Author/SLD)
