Initial validation of an instrument to measure teacher digital competence

This study aims to analyze a construct to determine the level of auto perception of teaching digital competence (TDC) based on the INTEF (2017) common framework. This instrument was designed and validated in Spain; it consists of 54 items grouped into five theoretical dimensions. This study is applied to 978 teachers in Mexico. The reliability index is .985, estimated with Cronbach's Alpha. The validity of the instrument is determined by exploratory factor analysis. Most factor loadings are above .400. The final instrument has five factors that give it a new meaning in some theoretical dimensions and allows asking questions for understanding self-perception in TDC development regarding validation in the Spanish context.
