This investigation focused on the characterization of adaptive behavior in students with or without intellectual disabilities in the Araucanía Region in Chile. The Inventory for Service Planning and Individual Programming (ICAP) was used with a sample of parents or legal tutors of 22 children with intellectual disabilities and 33 children without disabilities. The ages of the students ranged between 6 and 12 years, with a non-probabilistic cluster sampling design, with descriptive-comparative methods for analysis. Results show differences in adaptive behavior between the assessed groups, where students without disabilities show a higher level of development. Also both groups exhibit heterogeneous skill profiles, with motor skills being the most developed, and life skills in community being the least developed. These differences might have been affected by the presence of intellectual disabilities and by the educational contexts. This study is associated to the DI12- 0077 research project entitled “Psychometric Properties of the Spanish version of the inventory for service planning and individual programming (ICAP), in students of the city of Temuco”
