Confirmatory Factorial Analysis Applied on Teacher Evaluation Processes in Higher Education Institutions of Ecuador

The verification of validity and reliability of teacher evaluation processes in Higher Education Institutions of Ecuador, has been a topic of interest in recent years. The insertion of ICT in these processes allowed the creation of computer tools and statistical applications with the aim of improving the evaluation instruments, giving support in processes like item selection and factorial structuring. Typically, test reliability and validity has been calculated through techniques, such as Chronbach’s \( \alpha \) and Exploratory Factorial Analysis. However, previous studies have exposed their limitations and demonstrated that these methodologies do not guarantee scale of measurement validity. For this reason, the Confirmatory Factor Analysis emerges as an integrative alternative that provides a more adequate statistical framework, in addition to guiding the researcher towards the optimization of construction process and/or test adaptation. This article details the application of the Confirmatory Factor Analysis to teacher evaluation processes of higher education institutions of Ecuador, demonstrating its usability and benefits over commonly used techniques.
