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? The RAN risk profile performed at or above mean on all kindergarten measures except RAN (1.27 SD below mean), and its members were all readers, consistent with the double-deficit view. → Ozernov-Palchik 2017

q2 · i? · associational · r2
Profile description of the RAN Risk group (n=132, 10.86% of sample) from the LPA results; the group performed 1.27 SD below the mean on RAN while at or above mean elsewhere, and all members were readers.
"In contrast, the RAN risk group had intact performance on all other kindergarten measures (including PA), further supporting the independence of the RAN construct from PA."
Discussion¶
Learner Variables¶
- Phonological Awareness — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Kindergarten profile membership predicts differentiated 1st-grade reading patterns: the double-deficit group performed worse than all other profiles on nearly all measures — related
- PA and RAN deficit profiles are over-represented in low-SES schools, while the double-deficit profile distribution is proportional to school SES group size — related
- Latent profile analysis of kindergarten pre-reading measures yields six distinct performance profiles, including PA risk, RAN risk, and double-deficit risk groups — a broader claim this one bears on
- RAN predicts reading deficits but not isolated writing deficits, whereas phonological awareness is worse in children with isolated writing deficits — related
