Note: Comparisons are provided between Lincoln (L), District middle schools (1–4) and District (D). Units are state-normalized z-scores, which represent number of standard deviations above or below the mean. ∆z-score is the difference between grade 8 z-score and grade 5 z-score, with positive ∆z-score indicating “within-cohort” gains. See supplementary Table S3 for raw z-scores.
