This paper summarises the reading ability data collected from 476 children with low vision using the Neale Analysis of Reading Ability (NARA). The project aimed to generate standard reading ages for pupils with low vision using the NARA reading test. This would enable children's reading to be assessed against their partially sighted peers as well as their fully sighted peers. Standardised reading ages were generated using a linear regression technique to smooth the data. The data shows that the average reading ages for accuracy, comprehension and speed for the sample are generally below their chronological age when the comparison is made with their fully sighted peers. Guidelines for using the NARA with low vision students are presented.
