Background: In education, Information and Communication Technology (ICT) has gone from being a convenient option to a permanent necessity. For students and people with functional diversity, it is of seminal importance. It is therefore worth learning how professionals perceive digital tools and apps for people and students with functional diversity and autism: its requirements and potential. As no instrument to measure this exists, we have designed a questionnaire on the requirements and potentials of ICT and apps for assisting people with autism (DP-TIC-AUT). Methods: Our questionnaire has been subjected to content validity using a panel of experts, and construct validity, using Exploratory Factor Analysis and Confirmatory Factor Analysis, and Cronbach’s alpha and Composite Reliability. Results: Optimal results were obtained in the above values, thus confirming the validity of DP-TIC-AUT for use in the contexts of its validation. Conclusions: DP-TIC-AUT is a valid instrument. This opens up a range of possibilities for research, firstly descriptive, then of other kinds, and for the adaptation of the instrument to other contexts. This is the first step in improving the creation and use of ICT for people with autism.
