Evaluation of technical characteristics of Noe mentoring scale

Objective: In addition to structured methods, teacher development can be achieved through professional relationships. they're is a special kind of development-oriented relationship that is formed between an experienced, influential, and successful person with an inexperienced one. This relationship leads to the development of teachers' competencies by providing scientific, technical, and psychological support. This type of relationship is conceptualized as mentoring.

Methods: The current study was conducted to validate a scale designed by Noe for the quantification of this concept. Using a descriptive-correlational design and collecting data from a sample of 178 primary school teachers, the technical characteristics of our questionnaire were evaluated after translating and correcting the scale, its content validity was evaluated based on the criteria of appropriateness, clarity, and comprehensiveness and using the opinion of 10 experts. Agreement on the three criteria was equal to 80, 78, and 90 percent. To evaluate the model’s fit, indices such as chi-square/ df, the goodness of fit index, incremental fit index, Tucker-Lewis index, comparative fit index, root mean square error of approximation, and standardized root-mean-squared residual were used.

Results: The results of confirmatory factor analysis showed that the two-factor model has a good fit with the data; as the factor loads of the materials were obtained to be between 0.42 and 0.66 and were evaluated as moderate and strong. The internal stability of the scale was evaluated by Cronbach's alpha and composite reliability. Cronbach's alpha was obtained for dual dimensions to be 0.87 and 0.77 and the whole scale was equal to 0.90. The correlation of dimensions with the whole scale was also significant.

Conclusion: Overall, the results show that the Noe mentoring scale has acceptable reliability and validity and is a good tool for measuring this type of relationship among elementary teachers.
