Abstract

Teacher quality is one of the factors that determine students’ academic performance in secondary schools. The key objective of this study was to examined the validity and reliability of teacher quality instrument. The teacher quality questionnaire instruments was subjected to validity and reliability test. The research design was quantitative study using a total of six panels with vast knowledge in the area of educational management to validate, examine correctness and uniformity of the questionnaire if the instruments can be used for further analysis. Also, 100 teachers were selected from three senatorial district of Kwara state using the simple random technique to answer questionnaire prepared for reliability of the instrument. The findings revealed that I-CVI of 0.63 to 1.00, S-CVI 0.68 to 1.00 and KSCI of 0.68 to 1.00 instrument met require value of content validity. Likewise, the finding further shown that the reliability values for the teacher quality instruments were greater than 0.6. Thus, the teacher quality instrument was reliable to measure teacher quality from the teacher’s perceptions in the context of Kwara State Public Secondary Schools. In line with results, the study suggested that statistical tools like CFA and EFA should be used for teacher quality instrument by future researchers for validation so as to establish that the teacher quality instruments have higher standard.
