Background Prader–Willi syndrome (PWS) is characterised by hypotonia, hypogonadism, short stature, obesity, behavioural problems, intellectual disability, and delay in language, social and motor development. There is very limited knowledge about visual‐motor integration in children with PWS. Method Seventy‐three children with PWS aged 7–17 years were included. Visual‐motor integration was assessed using the Beery Visual‐motor Integration test at the start of the study and after 2 years. The association between visual‐motor integration and age, gender, genetic subtype and intelligence was assessed. Results Children with PWS scored ‘very low’ (−3 standard deviations) in visual‐motor integration and ‘below average’ (−1 standard deviation) in visual perception and motor coordination compared with typically developing children. Visual‐motor integration was higher in children with a deletion (β = −0.170, P = 0.037), in older children (β = 0.222, P = 0.009) and in those with a higher total IQ (β = 0.784, P
