Studies bearing on this claim

Do learners with disabilities reach lower achievement, graduation and postsecondary outcomes than their peers, by how much, and does it differ by disability type? This table gathers the studies behind this claim and the 14 narrower claims that bear on it: 10 distinct studies (9 associational, 1 qualitative), q2–q3, 0 of 10 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
