EAC Visual Data is an assessment tool, not a Grade Center or a Grade Center substitute. It is designed to improve the quality of exams and exam questions, rubrics and rubric performance criteria, as well as to trend student performance on learning outcomes across courses and over time.
All test questions, rubric performance criteria, and average scores in EAC Visual Data are presented on a scale from 0.0 (low) to 1.0 (high). Moreover, to calculate test and item reliability statistics accurately, EAC Visual Data does not support partial credit. Students either answer a test question correctly (earning them 1.0 point) or incorrectly (earning them 0.0 points).
