Classification accuracy analysis (Table 3.3) of how well MAP Growth spring RIT cuts predict MCA-III Mathematics proficiency, per-grade N from 3,355 to 5,621; the article prints "The overall classification accuracy rate ranges from 0.87 to 0.90" and AUC values of 0.78–0.88.

"The overall classification accuracy rate ranges from 0.87 to 0.90, which suggests that the RIT cuts are good at classifying students as proficient or not proficient on the state test."
