The Canadian Agility and Movement Skill Assessment (CAMSA) is a valid and reliable circuit-based test of motor competence which can be used to assess children's skills in a live or recorded performance and then coded. We aimed to analyze the intrarater reliability of the CAMSA scores (total, time, and skill score) and time measured, by comparing the live audio with the video assessment method. We also aimed to assess the interrater reliability using both audio- and video coding on a sample of 177 Spanish children. We found moderate-to-excellent inter- and intrarater video-audio intraclass correlation coefficients for the CAMSA score, time measured, time score, and skill score. Nonsignificant differences were found between video and audio recordings in the CAMSA score, time measured, and time score. Our findings support the rationale that different raters and scoring methods can accurately assess the participants' motor competence level using the CAMSA Spanish version.
