ELT well offers assessments for everyone, regardless of whether they speak English as a first or an additional language, and what level of English proficiency they have reached. After all, if learners are not progressing in English, it seems sensible to find out why, rather than make them struggle for another year in the hope that they will learn enough English to be able to tell us what the problem is! If we are not teaching them in the way that they can learn, they may never reach that point.
It is useful to find out as much as possible about how a learner is working, and to build a picture of his or her cognitive profile, so that we as teachers know how best to support him or her. We might also want to determine whether they have a specific learning difference, and what the nature of this difference might be, e.g. dyslexia, dyspraxia, dyscalculia, AD(H)D, Asperger’s Syndrome, or a combination of these. These SpLDs very often co-occur so it is important to be alert to the possibility of more than one being the cause of any difficulties that a learner is experiencing.
A formal assessment might be required in order to apply for exam access arrangements in school or Further Education exams, or to access the Disabled Student Allowance for students in Higher Education. A formal diagnosis can also be helpful for people in employment, who perhaps require reasonable adjustments to be made to their workplace, access arrangements for professional exams, or the Life in the UK test.
