Purpose: This study evaluated the feasibility of the "Start to Move" (S2M) digital assessment of children's fundamental movement skills being implemented by primary school teachers within PE lessons. Methods: Nine primary school teachers in the United Kingdom trialed S2M weekly over a 6-week period. Posttrial surveys and interviews were used to ascertain responses. Results: Feasibility was measured using seven dimensions of Bowen et al. framework; acceptability, demand, implementation, practicality, adaptation, integration, and expansion. Acceptance and demand of S2M was high with participants feeling that its contents aligned to the PE curriculum. Participants were able to implement S2M with PE lessons without assistance and stated that they would continue to use it within their teaching. They felt S2M would enhance their teaching and would recommend it to other teachers. Discussion/Conclusion: S2M is feasible for primary teachers to implement within PE lessons and has the potential to heighten the use of assessment for learning within PE in primary schools.
