In a recent thread on the IAPCHC listserv, a question was asked about the correlation of the WJ IV Visual-Auditory Learning test with Basic Reading Skills. I ran the correlation (by ages 4-18) in the WJ IV norm data. The raw correlations, along with a smoothed fitted curve, is presented below. It is obvious (and makes sense given the developmental nature of reading skill development) that the VAL test shows developmental trends, with the highest correlations occurring at the youngest ages (4-7/8).
