To ensure the platform’s usability and effectiveness, we conducted a thorough validation process that involved gathering feedback from a diverse range of stakeholders, including Vocational Education and Training (VET) professionals, families, and autistic users. This validation phase was crucial for assessing the platform’s strengths and identifying areas for improvement prior to its final implementation. The validation process included multi-phased user testing, where participants interacted with the platform and provided structured feedback on usability, content relevance, accessibility, and overall user experience. This initiative took place across Spain, Portugal, the Czech Republic, and Serbia, emphasizing inclusive participation and co-creation principles. By prioritizing the voices and real-world needs of users, we aimed to shape a platform that truly meets the needs of the community.
