We are experiencing a serious health crisis due to COVID-19 that has a major impact on the field of education. The educational system therefore needs to be updated and innovated, with the addition of digital resources, to adapt the teaching and learning processes to students with disabilities. To meet the goal of high-quality education, teachers must have adequate digital competence to face the educational demands that are placed on them. Therefore, the purposes of this study are: to know the teachers' knowledge about digital resources to support students with disabilities (O1); at each educational stage (O2), identify the variables that have a significant impact on the acquisition of teacher competence (O3); propose a selection of useful ICT resources for each type of disability (O4). An ex post facto design was used with 1194 teachers from Andalusia (Spain). The results showed the medium-low level of the teaching staff, especially in the higher education stage. In addition, gender, motivation, attitude and having students with special needs are determining factors in the development of teacher knowledge. The results highlight the urgent need for teachers to be trained in digital resources. We hope that the range of resources proposed in this study will help teachers enhance their teaching practice.
