This project team is developing and testing a prototype of the Ivymount Social Readiness System, a mobile app designed for practitioners to assess the social and emotional strengths and deficits of kindergarten through Grade 6 students with high-functioning Autism Spectrum Disorders (HF-ASD). The prototype app will include an assessment rubric and professional development resources to facilitate implementation. In the Phase I pilot study, 30 teachers who work with students with HF-ASD will use the prototype over a 4-week period. The researchers will examine whether the prototype functions as planned and teacher attitudes about integrating the technology into standard practice.
