Purpose:
The purpose of this study was to produce normative data for Rosner's Test of Visual Analysis Skills (TVAS, 1979).
Methods:
A total of 881 unselected children aged 5 to 10 years and in the first 4 years of school in Australia were tested to threshold on the TVAS. Percentile, mean, and standard deviation for each age group were calculated.
Results:
We found a steady increase in scores with grade and age and a significant difference in scores between most of the ages and grades. This progression indicates that the test accurately reflects increased sophistication in visual analysis skills. There was no significant difference between girls and boys.
Conclusions:
Normative data is presented in terms of percentiles for each age group. Interpretation of the scores is discussed.
