Abstract
Raw scores on the Standard and Advanced forms of the Raven Progressive Matrices were rescaled in a college sample by means of equipercentile equating to yield a common scale that accommodates a wider range of talent than do the raw scores of either form. The common scale is expressed as IQ with mean and standard deviation equated to the national normative sample for the Otis-Lennon IQ Mental Ability Test.
