AbstractImplementation of quality management systems in educational organisations is a fact in many countries. Schools adopt systems to establish an improvement plan, based on evaluating everything they do, thus searching for continuous improvement. Objective evidence of the improvement and changes must be gathered and tools and techniques are thus required to evaluate all of these changes. This paper presents a scale with a design and an analysis of its technical characteristics, using a total sample of 709 teachers and principals of 29 primary and secondary education schools of two Spanish regions. Results show that the overall reliability of the scale is very good, with a Cronbach’s α of .988 and values higher than .92 in each of the six dimensions of the scale. The item analysis shows the level of homogeneity, with values over .25, in all of them. The validity of the scale is also good since the dimensions and subdimensions used are consistent, and the empirical data and the unidimensionality of the construct is proven.
