A principal component analysis using oblimin rotation was performed on data collected from 905 classroom teachers drawn mainly from primary and secondary schools in Jamaica. Results of the analysis identified two dimensions: personal teaching efficacy and classroom management. Cronbach's alphas of the dimensions ranged from 0.646 to 0.854. The results also showed that school type, gender, and teacher status in the school organization had small but significant influence on the levels of participants' teacher efficacyenTeacher efficacySelf efficacyTeacher effectivenessBeliefsRating scalesTest validityTest reliabilityCaribbeanArticle
