Graph: A dataset of essays were graded by professional graders on a range of 1-10 and cross-referenced against the detailed criteria within the rubric to determine their real scores. Deviation was defined by the variation of scores from the real score. The graph contains an overall score (the average of all criterias) as well as each individual criteria. The criteria are the premade criteria available on Smodin's AI Grader, listed in the graph as column headings. The custom rubrics were made using Smodin's AI Grader custom criteria generator to produce each criteria listed in Smodin's premade criterias (the same criteria as the column headings). The overall score for Smodin Premade Rubrics matched human scores 73% of the time with our advanced AI, while custom rubrics generated by Smodin's custom rubric generator matched human grades 82% of the time with our advanced AI. The average deviation from the real scores for all criteria is shown above.

*Rubrics created using Smodin's AI custom criteria matched human scores 82% of the time on the advanced AI setting. Smodin's premade criteria matched human scores 73% of the time. When the AI score differed from the human scores, 86% of the time the score only differed by 1 point on a 10 point scale.

**The AI grader provides 100% consistency, meaning that the same essay will produce the same score every time it's graded. All grades used in the data were repeated 3 times and produced 100% consistency across all 3 grading attempts.
