q2 · i? · design · r2

Internal consistency analysis of the Spanish MAP Growth Reading pilot administrations (Fall 2018, Winter 2019, Spring 2019). The report states the "overall marginal reliabilities for all grades are in the 0.90s," interpreted as high internal consistency; no per-grade coefficients are quoted here.

"The overall marginal reliabilities for all grades are in the 0.90s, which suggests that the tests have high internal consistency."

Related Claims¶

• Marginal reliabilities of MAP Growth winter scores are comparable across engines and all in the 0.90s, with CBE showing slightly higher precision (lower SEM) — related
• Fall 2020 MAP Growth tests showed high levels of marginal reliability across all grades in both remote and in-person administration — related
• Spanish Math and Reading scores show high marginal reliability and moderate-to-strong test-retest stability, lowest for fall–spring and kindergarten — related
• MAP Growth reliability coefficients average about 0.95, with lower values in Science and early grades and stronger test-retest reliability over shorter intervals — a broader claim this one bears on
• Spanish MAP Growth Reading test-retest reliability ranges from 0.50 at Grade K to 0.83 at Grade 5, with no estimate for Grades 6–8 — related
