Background/aim: Current handwriting assessment tools are standardised mostly on typically developing students. This study estimated the intrarater and interrater reliabilities of the adapted scoring criteria, titled the Minnesota Handwriting Assessment‐Cerebral Palsy (MHA‐CP), for evaluating the effectiveness of handwriting interventions for children with cerebral palsy. Methods: We scored two batches of 20 random samples each from 80 handwriting samples produced by 30 children with cerebral palsy using the MHA‐CP to estimate the intrarater and interrater reliabilities, respectively. Results: Intraclass correlation coefficients exceeded 0.95 for both intrarater and interrater reliabilities for all quality subscales of the MHA‐CP. Conclusions: The MHA‐CP is shown to be a reliable measure of the manuscript handwriting performance of children with cerebral palsy who are in Grades 1 and 2. Further empirical testing is recommended to confirm its validity as an outcome measure for this population.
