The inclusion of all learners in mainstream classrooms is an objective for schools internationally. The aim of this study was to test the psychometric properties of the newly developed Inclusive Practices Scale (IPS) to determine if the intention to use inclusive practices could be predicted from participants' atti-tudes and efficacy scores. Participants included 390 pre-service educators from four countries (Australia, India, Canada, and Hong Kong). Results suggest that the IPS is both a reliable and valid instrument, with teaching efficacy the strongest predictor of inclusive practice intentions. The IPS could be a meaningful tool in determining pre-service and in-service educators' intentions to use inclusive practices. Crown Copyright © 2021 Published by Elsevier Ltd.
