The Reading Age (RA) indicates the typical age for an individual with a
given value of the STAR Reading Scaled Score. The RA score
is an approximation based on the demonstrated relationship between STAR
Reading and other tests of student reading ability, which were normed in the
UK. RA scores are transformations of the STAR Reading Scaled Score.
The scale is expressed in the following form: YY:MM, where YY indicates the
reading age in years and MM the months. For example, an
individual who has obtained a reading age of 7:10 would be estimated to be
reading as well as the average individual at 7 years, 10 months of age.
