Abstract
Objective: This research was conducted to identify inter-rater reliability of the Manual Ability Classification System(MACS) for children with cerebral palsy between 1 and 6 years of age and to compare inter-rater reliability according to age groups.

Methods: 5 occupational therapists assessed 31 children with cerebral palsy between 1 and 6 years of age using MACS. The guideline including fine motor and self-care activities appropriate to age was established and referred to during assessment. Inter-rater reliability was analysed using weighted Cohen`s kappa.

Results: Inter-rater reliability of the MACS was ¥ê=0.78 for children aged 1¡­6 years, ¥ê=0.82 for children aged 1¡­2 years, ¥ê=0.75 for children aged 2¡­4 years, and ¥ê=0.78 for children aged 4¡­6 years.

Conclusion: Inter-rater reliability of the MACS for children with cerebral palsy between 1 and 6 years of age was beyond good. Especially, inter-rater reliability of the MACS for children aged 1¡­2 years was the highest. It is meaningful to suggest a guideline including fine motor and self-care activities appropriate to age. For further development of the MACS for young children, it is necessary to identify inter-rater reliability according to whether a guideline including fine motor and self-care activities appropriate to age is used or not. Also, it is necessary to identify validity of a guideline including fine motor and self-care activities appropriate to age.
