Estimated Reading Age (ERA) indicates the typical reading age for an individual with a given value of the Star Reading Scaled Score. This provides an estimate of the chronological age at which students typically obtain that score. The ERA 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. Estimated Reading Age scores range from 6:00 (6 years and 0 months) to 16:06 (16 years and 6 months).
This score appears on the Star Diagnostic Report and the Star Reading Range Report.
