The use of criterion-referenced measurement has recently been extended from paper-and-pencil tests to observational recording procedures. While numerous authorities discuss procedures for collecting and reporting observational data, little attention has been given to the issue of data interpretation. The present paper explores this issue by examining and illustrating techniques for visually inspecting graphically displayed data. These procedures may assist the educator in determining the impact of intervention procedures on learner performance.
