Abstract

The Early Development Instrument (EDI) is a widely used teacher rating tool to assess kindergartners’ developmental outcomes in Canada and a number of other countries. This paper examines the measurement invariance of EDI domains across ESL status and gender by means of multi-group confirmatory factor analysis. The results suggest evidence of measurement invariance for physical health and well-being, social competence, emotional maturity and language and cognitive development domains. Moreover, the communication skills and general knowledge domain did not show acceptable fit in terms of RMSEA. The results and potential explanations are discussed.

L'instrument de mesure du développement de la petite enfance (IMDPE) est un outil d’évaluation largement utilisée pour mesurer le développement des élèves en maternelle au Canada et dans d’autres pays. Cet article porte sur l’équivalence de mesure des domaines de l’IMDPE entre le statut d’ALS et le sexe par une analyse factorielle confirmatoire multigroupe. Les résultats font ressortir des preuves d’équivalence de mesure pour les domaines de la santé physique et le bienêtre, la compétence sociale, la maturité affective, le développement langagier et cognitif. De plus, le domaine des compétences en communication et des connaissances générales n’a pas démontré une correspondance acceptable par rapport à l'erreur quadratique moyenne de l'approximation (RMSEA). Nous discutons des résultats et proposons des explications possibles.
