How does reading relate to language? How do we reconcile the structure of reading with profiles of strengths and weaknesses?

developmental scale scores from the FRA’s RCT, SAT-10, and FCAT 2.0
¡ Print-related measures were moderately correlated in K (PA with LS, .48, and with SESAT WR, .58; and SESAT WR with LS, .51). OL measures were moderately correlated with each other. ¡ In G1-G2, print-related measures were more strongly correlated: SAT-10 with WR (.75 in first and .58 in G2); WR & Spell in G2 (.77). Oral language measures were moderately correlated with each other in all three grades and VOC was moderately correlated with SAT-10 in G1 (.58) & G2 (.62). ¡ The three RC measures were strongly correlated, with the RCT bivariate correlations ranging from .67 in G8 to .81 in G5. FCAT and SAT-10 correlations ranged from a low of .71 in G8 to a high
these grades (.31 to .46) as were the bivariate correlations of WRT (.29 to .51).

¡ LPA identified 5-6 classes in K-5 and only 3 in secondary grades. ¡ Latent profiles significantly related to standardized reading
variance, with the mode being 42%. ¡ Range of Hedges g (for average absolute values of the standardized difference in reading outcome across all latent classes) was 1.10 (in K) to 2.53 (in G5). ¡ Profiles above G5 fell into a pattern of low, medium, and high. ¡ The 5-6 reading and language profiles found in the elementary grades reflect heterogeneity of skills.
¡ Fact that latent profiles accounted for substantial differences in RC in a large diverse sample of students spanning 11 grades contributes to a field dominated by (a) unreliable or unstable classifications, and (b) LCA of clinical samples (e.g., Catts et al., 2012; Justice et al., 2015) or low-performing students (Logan & Petscher, 2010; Brasseur-Hock et al., 2011). ¡ Heterogeneity of skill profiles in the elementary grades in contrast to the low, medium, & high profiles in the secondary grades suggests focusing on differentiating instruction in K-5. ¡ Importance of FRA academic language (vocab and syntax) to RC, more than word recognition, apparent in G3 and above.
¡ Cross-sectional rather than longitudinal. [Replications of findings across grades helps.] ¡ Profiles and their relations to reading outcomes are limited to the measures used. [At least a latent variable of reading comprehension was used, which related strongly to the single measures in the FRA reading and language measures.] ¡ Next step is to test results of the heterogeneous profiles from this exploratory LPA with confirmatory latent class analysis.
