Subclaims¶

q2 i? Test-retest reliability with alternate forms ranges from 0.50 at Grade K to 0.83 at Grade 5, and no test-retest reliability was computed for Grades 6–8 because those grades took only one administration. → NWEA 2021

q2 · i? · design · r2

Reliability analysis of pilot data from the Fall 2018, Winter 2019, and Spring 2019 administrations of the Spanish MAP Growth Reading pilot. The report states "Test-retest reliability coefficients range from 0.50 at Grade K to 0.83 at Grade 5," with no coefficient for Grades 6–8.

"Test-retest reliability coefficients range from 0.50 at Grade K to 0.83 at Grade 5. There is no test-retest reliability for Grades 6–8 because only one test administration was taken by these grades."

Related Claims¶

• Spanish Math and Reading scores show high marginal reliability and moderate-to-strong test-retest stability, lowest for fall–spring and kindergarten — related
• Marginal reliabilities for Spanish MAP Growth Reading are in the 0.90s across all grades — 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
