For me, testing is a privilege to understand a student’s ability to access, integrate, and process his or her learning. It is the opportunity to confirm known strengths and identify challenges in the complex setting of learning. Comprehensive cognitive and educational tests assess the important modalities of auditory, visual, and motor learning that lean on memory capacities, organization skills, executive functioning, and the ability to attend. These highly specialized tools can teach us much about how an individual learns effectively and efficiently. Administered in the relaxed setting of a home library, these tests are standardized measures that have a long history of reliability and credibility.
