Applicants are asked to declare any disability on the UCAS application form. Provision of this information is voluntary and applicants are advised that they may choose only to inform the institutions to which they apply directly. Disability data are available only for home applicants. The wording used to instruct applicants on how to declare a disability changed between 1998 and 1999 (unseen disabilities). In addition, for 2003 entry the Dyslexia category has been extended to other specific learning difficulties (including Dyslexia); the Personal care support category has been abolished; and a further, Autistic disorder, category has been introduced. Disability comparisons between 2003 entry and earlier years should, therefore, be treated with caution.
