Purpose:  To evaluate inter- and intrarater reliability, of the Eating and Drinking Ability Classification System (EDACS) for children and adults with cerebral palsy (CP) in Sweden.

 Methods:  Four speech and language pathologists rated EDACS from videos of 30 individuals with CP, 3 to 62 years, (mean 21 y, 10 m, SD 18 y, 6 m), six at each level of the Gross Motor Function Classification System (GMFCS). Inter- and intrarater reliability were estimated using Intraclass Correlation Coefficient (ICC) with 95% confidence interval.

 Results:  Interrater reliability was excellent, ICC 0.98 (95% CI 0.95-0.99) for EDACS levels I-V and ICC 1 for need for support, as was intrarater reliability, ICC 0.97 (95% CI 0.93-0.98) for EDACS levels I-V and ICC 0.99 (95% CI 0.99-1) for need for support.

 Conclusions:  When rated by speech and language pathologists, EDACS shows excellent inter- and intrarater reliability for children and adults with CP. EDACS can identify eating and drinking ability and need for support in individuals at all GMFCS levels.
