This essay focuses on what impact developmental dyslexia has on assessment and grading in the second language teaching of English in the Swedish educational system. The data presented in this essay are based on six semi-structured interviews with English language teachers of lower and upper secondary schools from the south-eastern parts of Sweden. The interviews were conducted in Swedish, and the collected data have been translated into English. The inquiries of the interviews focused on the teachers' awareness of dyslexia and its impact on learning and teaching, as well as how they worked with and their considerations made when assessing and grading dyslexic pupils. The interviews specifically enquired what particular challenges arose in the assessment and grading process, what provided aid, and what could be done to provide further relief during this process. The results show that the assessment and grading of dyslexic pupils is similar to the general practice. The teachers do, however, accommodate the dyslexic pupils' needs in the teaching and carefully consider their difficulties when assessing and grading. The teachers use, for example, spelling programs and such technical aids to help them, to some extent, disregard dyslexic difficulties while assessing. However, results show how the teachers are not able to transfer their awareness of dyslexia and its implications into the assessment and grading situation, suggesting that the teachers' own ability to assess dyslexic pupils is somewhat inadequate.
