The Assistive Technology Portal originated from a project called "Multifunction Room Teachers' Qualification for Alternative Communication Development of Students with Special Educational Needs" with the purpose to democratize information in the Assistive Technology area. This Portal was the main product of this study, whose objective was to plan, implement, and assess the effects of a qualification designed to teachers of Multifunctional Resource Rooms in Rio de Janeiro. To this end, we researched the profiles of teachers and students, as well as the operation of these rooms. Nineteen teachers participated in this study, which used the action survey methodology. Data collection tools comprised questionnaires, field textbooks and Alternative Communication material analysis, adapted pedagogical activities, and stories and games developed in the course. The qualification strategies have been customized to the group's demands, and the methodology adopted was extremely favorable because it enabled the group to have an active participation throughout the qualification process. Sharing material on the internet originated the idea of developing the Assistive Technology Portal, and the participation of teachers with their views was essential for the development of the website.
