The content and construct validity and reliability of the Revised Science Attitude Scale for Preservice Teachers as a scale for measuring the attitude of preservice elementary teachers toward the teaching of science were re-examined. The instrument is intended to measure four subcomponents: comfort-discomfort, need, time, and equipment. Data were generated on two subsamples (n1=59 and n2=60) and the sample (N=378). Frequency, intercorrelations, Cronbach's Alpha, and principal components analysis with varimax rotation were used to analyze the data. Means tended to fall within the 2.00 and 4.00 range with standard deviations hovering around 1.00. Neutral responses beyond 35% were limited to statement 7. Five factors were extracted in the principal components analysis, explaining 55.1% of the variance. Eight statements failed to load on any factor. Statements of teacher anticipation about teaching science heavily loaded on Factor I. Loading equally on Factors I and II were statements in the subcomponent equipment. Of the three statements in the subcomponent time, two loaded on Factor III. Only statements in the subcomponent need loaded on Factor IV and V. Reclassification of some statements seems warranted.
