Abstract	The hierarchical latent regression model (HLRM) is a flexible framework for estimating group-level proficiency while taking into account the complex sample designs often found in large-scale educational surveys. A complex assessment design in which information is collected at different levels (such as student, school, and district), the model also provides a mechanism for estimating group differences at various levels and for partitioning variance components among those levels. This study examines parameter recovery in the HLRM and compares it to regular latent regression models (LRMs) through simulation for various levels of cluster variation. Results show that regression effect estimates are similar between the HLRM and the LRM, in particular under small cluster variation. Similarly, student posterior mean estimates and marginal maximum likelihood mean estimates for student groups are comparable across the two model approaches. However, substantial differences are found for the residual variance estimates, the standard errors for regression effect estimates and related standard errors for group estimates, and for students posterior variance estimates. As expected, these differences are larger when the variation across clusters is larger, since a substantial portion of variance remains unexplained in LRM. (As Provided).
