For post-primary education in the State of Suwaiq.

The scale’s content validity was measured by content validity, internal consistency, factor validity, discriminatory validity and structural validity, which gave important, acceptable and statistically significant indicators. The reliability coefficient using the Alpha Cronbach equation for this scale, which amounted to 0.88, and the split-half method using the Spearman-Brown equation, which amounted to 0.89, so the current scale is valid for use and application in the Omani environment.
