In this project we are going to try to explain, first of all, the assessment of learning difficulties in reading. We will highlight those signs that indicate that students need ordinary educational aids, and which are the instruments that help us to identify them. Secondly, we will talk about the assessment of learning difficulties in reading, differentiating between the main limitations that students with learning difficulties in writing present and the phases that this type of student goes through. Finally, we will talk about the diagnostic task, the assessment tools and the formulation of reports as well as the educational intervention that can be carried out.
