Rescales DRP-Difficulty (Degrees of Reading Power) into grade equivalent (GE) units using the estimated difficulty level values obtained from the Rauding Scale. Finds the revised scale is accurate to within one graded level for lower grade materials and to within two grade levels for upper grade materials. (MM)

Converts silent reading rates into grade equivalent units. Finds that growth in reading rate is approximately constant each year in school for typical students. Presents grade equivalent data which provides reasonably valid, criterion-referenced grade equivalents that may be used to evaluate the status and progress of individuals or groups. (RS)
