Two key aspects for well-being, success in learning and education are the development of a positive academic self-concept and a good reading comprehension in the English language. In many schools, some subjects are taught in this language. In addition, it is the language of globalization and science. Students diagnosed with dyslexia usually present difficulties in both areas, so this paper aims at being a meeting point for these three concepts through quantitative research. The objective is to analyze the academic self-concept and the level of reading comprehension in the English language of 15 students with diagnosis and 15 without a diagnosis of dyslexia through the statistical package JASP v.0.12.2. The results obtained allow us to know the correlation and differences between self-concept and reading comprehension in the English language of both groups. Moreover, it will serve as a starting point for future research projects.
