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.
q1 i? A student who makes average growth maintains their achievement percentile status; positive changes in percentile require growth exceeding average. → MAP Growth Goal Explorer user guide and FAQ 2026

q1 · i? · design · r1
Explanatory statement from the guide's FAQ on goal difficulty, illustrating that average growth preserves relative standing. The guide explains that "growth must exceed the average" for percentile gains, offering the 30th-percentile example as illustration rather than tested evidence.
"if a student who scores at the 30th percentile in the fall makes average growth, the result is maintenance of their status at the 30th achievement percentile for spring. To gain ground and see positive increases in a student's achievement percentile, growth must exceed the average."
Discussion¶
Related Claims¶
- The published norms allow normative interpretation of both status and fall-to-spring growth, e.g., an Algebra 1 student at the 55th fall percentile has an expected gain of 8 RIT with growth SD of 9, and an 11-RIT gain places the student at the 62nd growth percentile. — related
- Under the 2025 norms, higher math growth expectations lower conditional growth percentiles for higher-growth students — related
- Norm shifts can change teacher evaluation CGP outcomes independently of instructional quality — related
- Aspirational Growth defaults to 60th-percentile growth (met by about 40% of similar students) and is selectable from the 55th to 95th percentile in 5-percentile increments — related
