Clinical assessment can document student progress; progress is demonstrated by an increase in standard scores or percentile ranks, not by an increase in age or grade equivalent scores. (dyslexiaida.org)
For example, a 3rd grader gets a grade - equivalent score of grade 5.8 on a group achievement test. (hoagiesgifted.org)
This can result in grade 2 or 3 equivalent scores almost immediately upon school entrance. (hoagiesgifted.org)
