| Abstract: | Dyer, et al. (1967) have proposed a model for school system evaluation. The usefulness of the indices obtained from this model depend on the reliability or stability of the indices. This study presents evidence related to the stability of these indices when pupils and factors related to time are considered as sources of error. |
