  1. Significance: ***P<0.001, **P<0.01, *P<0.05.
  2. Note: R2 is model explained variance; β (SE) is mean (standard error) contribution of Lincoln enrolment, reported in z-scores; ∆R2 is explained variance attributable to Lincoln enrolment; P-values are from F-tests to quantify significance of Lincoln enrolment-attributable increase in explained variance. Other predictors include gender (female), English learner, special education, free or reduced priced lunch, ethnicity (Hispanic), race (Black) and previous strand z-score. See supplementary Table S4 for full models.
