Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Marginal reliabilities ranged 0.89–0.98 in Math and 0.84–0.97 in Reading; test-retest reliabilities were highest for winter–spring and lowest for fall–spring, with kindergarten lowest overall. → MAP Growth Technical Report Spanish Addendum for 2024–2025 2026
q2 i? Test-retest stability declines as the interval lengthens, which the report attributes to true academic growth occurring between fall and spring. → MAP Growth Technical Report Spanish Addendum for 2024–2025 2026 (2)

q2 · i? · design · r2
Marginal reliability analysis across terms and grades (Table 4.7). Reliability generally increased across grades, with the lowest estimates in kindergarten; winter and spring administrations tended to yield slightly higher estimates than fall.
"In Math, reliability values range from 0.89 to 0.98, while in Reading, values range from 0.84 to 0.97."

q2 · i? · design · r2
Test-retest reliability with alternate forms across consecutive windows (Table 4.8). The report explains "the fall–spring interval spans more time for true academic growth to occur, which reduces stability coefficients"; Math high school fall–spring dropped to 0.52.
"winter–spring reliabilities are highest, fall–winter reliabilities are slightly lower, and fall–spring reliabilities are lowest"
