Studied a new approach, based on Rasch model item response theory, to age equivalence scores as a basis for mental age and the calculation of ratio IQ. Results for 1,719 children and adolescents suggest that the new ratio IQ had consistent criterion and construct-related validity at the same level as standard-score IQ. (SLD)
