Using data from the Disentangling Inclusion in Primary Physical Education (DIPPE) Erasmus+ project, this study aimed at investigating teachers' practices related to inclusion of children with additional needs (AN) in primary physical education (PE) and identifying supports that could enhance these practices. Responses from 1170 primary teachers across nine European countries to an online questionnaire were analysed. Although inclusion was regarded as important, only 30% of children with AN were reported as being always included and engaged in PE. Teachers considered guidance on children's motor needs and video-based resources particularly useful in promoting inclusion. Implications of the findings within the DIPPE project and more broadly are discussed.
