In this study, we aimed to report the experience of occupational therapists based on the theoretical reference of Collaborative Consulting. The experiment was carried out in two children education schools of the regular school network from two small cities in countryside of the state of Sao Paulo. The methodology is characterized by a case study and the information was gathered within the period of six months, through open interviews and a field diary, along with the intervention planned by the Extension Project Collaborative Consulting on the school inclusion of children suffering from development disorders - an Occupational Therapy procedure proposal. Subjects from two schools were used as targets for this intervention: two students with diagnosed autism, their mothers, and the schools' technical teams: the pedagogical coordinators, the teachers, the monitors, and the principals. The proposed intervention began with the construction of a corporation between the actors involved and the organization of the meetings, which consisted of an environment for sharing the experiences as well as for action planning. The results were positive concerning the effectiveness of school inclusion, highlighting the access and permanence of children in school, the facilitation of their learning, and the awareness of the involved actors regarding diversity, respect and team work. The action of the occupational therapist occurred on the articulation of the team work, the support towards awareness, and the identification of needs and achievements, evaluating and building together with the strategies and actions. These actions contributed to the analysis of the activities and orientations about their possibilities of adaptation and flexibility, on the support offered to the actors involved regarding the rules, legislation and specific aspects of each child.
