Why Grading Power

Peer grading shouldn't be a simple average
Students differ in how accurately they interpret a rubric. One student may consistently grade too generously, another too harshly, while another closely applies the grading criteria.Grading Power accounts for those differences by giving more influence to students who demonstrate greater grading accuracy over time.

How Grading Power Works

Accuracy builds Grading Power

01. Students evaluate
Students assess anonymous peer work using the instructor’s rubric.

02. Accuracy is measured
Kritik compares each student’s scoring with the final Creation Score or the instructor’s grading standard.

03. Grading Power adjusts
Students who evaluate more accurately build stronger Grading Power, giving their future evaluations greater influence.

Grading Power evolves throughout the course as students gain more evaluation experience.

Grading Power in the Kritik Loop
A grade that reflects more than the final submission.

Creation Score

Measures the quality of a student’s submitted work based on peer evaluation. Peer ratings are weighted using evaluator Grading Power.

Evaluation Score

Measures how effectively students evaluate others, including the accuracy of their rubric scoring and the quality of their written feedback.

Feedback Score

Recognizes students for completing the feedback loop by rating the evaluations they receive.


You control the weighting.
Instructors decide how much Creation, Evaluation, and Feedback contribute to the overall activity grade.

Calibration + Grading Power

Start with your grading standard.
Calibration Activities let students practice applying your rubric to submissions you have already graded. This helps establish a stronger baseline for Grading Power before students begin evaluating one another.

Instructor standard → Student calibration → Initial Grading Power → Continued peer evaluation → Grading Power evolves

Grading Power in Action
What happens when students grade differently?

The generous grader
Alex gives almost every submission full marks. As their scores repeatedly differ from the final scores, their Grading Power decreases.

Result: Persistent grade inflation has less influence on peer grades.

The harsh grader
Jordan produces strong work but consistently grades peers more harshly than the rubric warrants.

Result: Being a strong student doesn’t automatically make someone a strong evaluator.

The improving evaluator
Taylor initially struggles to apply the rubric consistently but improves through calibration and repeated practice.

Result: Evaluation becomes a skill students can develop over time.

Instructors Stay in Control
