Abstract: The early child development instrument (EDI) has become an important tool for screening children at entry into kindergarten in order to assess their development in five areas. After more than 10 years of its initiation and widespread use, it’s time to rethink about the tool’s theoretical and empirical basis. In this study, we applied factor analytic methods to re-examine the factorial structure and test the goodness of fit of several alternative models, using the 2011 EDI data for the province of Alberta. We also analyzed all 103 items from a classical test theory perspective to investigate the relevance of items to the definition of vulnerability postulated by the EDI developers. Changes need to be made to accommodate alternative factorial structure and, if possible a short form of EDI is to be developed, as there is evidence that reliability is high even with fewer items. A number of questions are addressed, aligned with specific objectives. Copyright Springer Science+Business Media Dordrecht 2015
