The Work Components Study (WCS) questionnaire is a measure of work motivation with predictive powers as a selection device on a probabilistic basis for industrial managers. This study established the factorial validity and reliability of a modified WCS-the Educational Work Components Study (EWCS) questionnaire. The sample of 745 included 153 senior and forty-two graduate students and 118 administrators and 432 teachers randomly selected from three school districts. The data analyses consisted of varimax orthogonal and maxplane oblique R-factor analysis procedures and Cronbach’s estimate of internal consistency. Instead of sixty-six items and seven prevalent factors in the WCS, fifty-six items and six unidimensional factors paralleling the original instrument were found in the EWCS. The reliabilities of the six factors ranged from .73 to .83. These findings coupled with the strong theoretical foundation of the EWCS indicate a high potential for probing many provocative relationships based on work motivation.
