RESUMEN
In recent years, many psycho-educational technologies were studied to address the school-related difficulties encountered by students with autism spectrum disorder (ASD). However, most of them remain individual-centered and do not consider the social environment. To fill this gap, this study reports on the user-centered design of a web-based support tool, which aims to support communication and coordination between parents, school staff and health professionals of middle and high school students with ASD, in the context of elaborating, implementing, and following an Individualized Education Plan. The study followed a two-step design process: (1) a need analysis for identifying information domains deemed important by the stakeholders; (2) through a participative iterative design process, a panel of professionals and parents provided ideas and feedbacks on the design, which was integrated in subsequent prototype versions of the "ToGather" app. Supplementary Information: The online version contains supplementary material available at 10.1007/s11423-021-10073-w.
