q2 i2 Correlations between teacher-assigned grades and standardized test scores range from r = .30 to r = .60, and teachers' judgments correlate about r = .56 with actual test performance. → Nicolas Hübner 2026

Evidence¶

Nicolas Hübner 2026¶

Nicolas Hübner, Juliane Rutsch, Ann-Kathrin Schnelle, Mia Herkommer, Evelin Ruth-Herbein, Benjamin Fauth. (2026). To Grade or Not To Grade? Demystifying a Centuries-Old Debate. Educational Psychology Review. https://doi.org/10.1007/s10648-026-10156-1

q2 · i2 · review · r3

The review reports, citing Borghans et al. (2016), Brookhart et al. (2016), and Hübner et al. (2020), that grade–test-score correlations "range from r =.30 to r =.60". The review attributes this to prior studies it did not re-analyze.

"Evidence of the validity of grades is often sought by computing correlations between teacher-assigned grades and external performance measures, such as standardized test scores, which were found to range from r =.30 to r =.60 in prior studies"
