This Chapter has been written by Anita Keates, a specialist dyslexia teacher and educational consultant who has many years’ experience of working with SEN students of all types. At the time of writing (2001), she was chair of the computer committee of the British Dyslexia Association. Anita works in two schools: Foxhills Technology School, a comprehensive in Scunthorpe, North Lincolnshire; and St. Hugh’s School, an independent school at Woodhall Spa in rural Lincolnshire. The former caters for students aged 11–16 years and the latter for students aged 3–13 years. Anita has incorporated LASS 11-15 into the SEN assessment processes in both these schools and here describes how the program has been applied in these different settings.
