Introduction
The national adult reading test otherwise known as NART, was devised in 1982 by Hazel Nelson, as a device to determine premorbid intelligence, and is used frequently in patient assessments and research. As an estimate of IQ, this test is utilised on individuals with declining mental health that is affecting their functioning ability, particularly cases of dementia and often schizophrenia and brain damaged patients. NART consists of 50 irregularly spelt words. Presented on a list, participants are required to read the words aloud, whilst receiving encouragement from the tester. This test relies on reading ability and pronunciation
