Abstract: To test the reliability and validity of the Teacher Self-Efficacy Scale, a cross-sectional online survey (16 items) was distributed via Google Forms to teachers at Mt Mellery Mission School in the Nyanga District of Zimbabwe. Validity and reliability were tested. The internal consistency for items and the entire scale, as well as other reliability measures, were tested. Also, the construct validity and the criterion-referenced validity were measured. The construct validity, criterion-referenced validity, internal consistency reliability, and split-half reliability showed good results. The Teacher Self-Efficacy Scale achieved a correlation between Forms = 0.748; Spearman-Brown Coefficient rSB = 0.856; Guttman Split-Half Coefficient rsb = 0.788; Cronbach’s Alpha α = 0.844. The Teacher Self-Efficacy Scale is valid and reliable.
