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? Students' relative age among their peers is related to their probability of disability classification. → Elizabeth Dhuey 2010

The study positions itself as extending "recent findings of a relationship between the relative age of students among their peers and their probability of disability classification," testing this relationship with nationally representative survey data spanning 1988-2004.
"This study extends recent findings of a relationship between the relative age of students among their peers and their probability of disability classification."
Discussion¶
Learner Variables¶
- Age and Developmental Stage — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Being a year older at kindergarten entry leads to higher initial achievement — the general claim this finding bears on, with the studies behind it
- An additional month of relative age among peers decreases the likelihood of receiving special education services by 2-5 percent — a narrower finding that bears on this claim
- Having older classmates boosts a child’s test scores but increases the probability of grade repetition and diagnoses of learning disabilities such as ADHD — related
