Abstract: Critical Thinking assessment focus of this study: researchers created a 6 category, 6-point scale analytic rubric; each category containing 2-3 bullets describing characteristics of each performance level. Rubric used to assess critical thinking prompt responses in various written and visual formats; calibration was for rubric and assignment prompt interpretations. Iterative discussions and 20-30 test sample scoring took place: a companion document with rubric notes was composed and refined during calibration for use during actual scoring (contained notes and provided space for raters to annotate reasoning behind scoring).
