This study investigates the validity of Cipp assessment model in assessing the function of the instruction centers. It is conducted through descriptiveanalytic method. The statistical population consists of 90 managers and experts of the instruction centers of National Iranian Petrochemical Company. After studying the initial statistical population and agreement of their conditions with the research needs, 60 people were selected as the statistical sample. The data were collected through questionnaire. The questionnaires validity was measured through Chronbach’s α and a coefficient of 87% was obtained which indicates an acceptable correlation of the questions and absence of significant dispersion among them. Furthermore, some experts confirmed face and content validities of the questionnaires. Cipp model was tested through structural equations model and the data were analyzed through binomial test, Friedman variance analysis test, correlation test, and t-test. The results indicate that the experts have confirmed the four dimensions of the model and its twenty criteria and further verified their ability to assess the instruction centers. In addition, there is a significant relationship among the dimensions, criteria, and variables. This indicates that the overt variables measure the covert variables significantly.
