Most provinces and states that require students to take large-scale assessments provide information about the tests for parents; however, parents vary in their uses of this information. In this study, parents in an urban Ontario elementary school were surveyed about where they obtained information about the Ontario assessments, what they knew about the assessments, and what they believed about the assessments. Most of the parents were knowledgeable about the assessments and held positive opinions. In general, the more sources of information they used, the more knowledgeable they were, and the more knowledgeable they were, the more positive were their opinions about the assessments.
