Teachers’ professional identity: validation of an assessment instrument for preservice teachers

Abstract

This study aims to develop and validate an instrument to analyse future Secondary Education teachers' perceptions regarding the development of Teachers' Professional Identity (TPI). The data were collected from a sample of 733 participants who were students enrolled in the Master's Degree for Secondary Education teachers. The psychometric properties of the instrument were obtained by analysing content, and comprehension validity, construct validity and reliability. A first subsample was used for an Exploratory Factor Analysis, and a second one to verify the identified factor structure via Confirmatory Factor Analysis. The instrument is made up of 31 items in four scales namely the understanding of TPI, the development of TPI at various educational levels, the development of TPI in comparison with that of other professionals and the influencing factors. The results show that it has high levels of validity and reliability. Therefore, it provides TPI research field with an instrument to assess it during the initial teacher training period in consecutive training models where it seems to occur more identity crisis.
