The aim of the study was to test the Job Characteristics Model (JCM) developed by Hackman and Oldham to an empirical situation, to grades 11 and 12 educators, in 15 selected secondary schools, to investigate the level of the five core job dimensions, i.e. skill variety, task identity, task significance, autonomy and feedback, also to establish the level of the three critical psychological states (experienced meaningfulness of the work, experienced responsibility for outcomes of the work and knowledge of the actual results of the work activities), as well as the personal and work outcomes (only motivation and work performance), all these in relation to race and gender. A self-designed questionnaire was administered to 15 schools in Qwaqwa where each principal was requested to distribute among 10 grades 11 and 12 educators. The results showed that even though the five core job dimensions are present, autonomy and feedback were not fairly well presented especially among Blacks. Regarding the critical psychological states, experienced meaningfulness of the work was well presented because of the contribution made by three core job dimensions (skill variety, task identity and task significance), while the two others (experienced responsibility and knowledge of actual results) were not fairly well presented especially among the Blacks because of the lack of contribution by the responsible core job dimensions (autonomy and feedback). These also influenced motivation and the rate of work performance (personal and work outcomes) among Blacks, which were not fairly well presented. The study recommends that the core job dimensions of educators’ job be improved especially with regard to autonomy and feedback, which they should know whether it is negative or positive. It further recommends that a more detailed one be conducted which might confirm or disprove the propositions of the job characteristics model.
