Onlythe WJ III COG tests that comprise the Broad CHC Ability clusters and the WJ III ACHtests that comprise the primary academic clusters and two oral language tests wereincluded in the present study. Tables 2 and 3 describe the tests, clusters, and abilitiesmeasured by the WJ III. Students were administered U.S. standardization versions ofthe WJ III tests, and scores were calculated with the WJ III NU norms. WJ III NU ACHForm B is the Canadian version of the WJ III NU ACH and was used in the presentstudy. In the WJ III NU ACH Form B Canadian, the majority of the test is exactly thesame as the WJ III NU ACH Form B, however, a number of items were changed to moreappropriately reflect Canadian content (e.g., coins, measurement, spelling).8
