As described at the Riverside web page:
This bulletin examines the use of the Woodcock-Johnson III Normative Update (WJ III NU) Tests of Cognitive Abilities and Tests of Achievement with a random sample of 310 school-age Canadian students. Results were compared with a matched sample of U.S. subjects selected from the WJ III NU standardization sample using WJ III NU norms. While some minor score differences are reported across the two samples, the study findings generally support the use of the U.S.-based WJ III NU norms with Canadian school-age populations.
