studies are often focused on growth in student performance and
background variables that can explain developmental differences
across examinees. To study educational progress, a flexible latent
variable model is required to model individual differences in growth
given longitudinal item response data, while accounting for
time-heterogenous dependencies between measurements of student
performance. Therefore, an item response theory model, to measure
time-specific latent traits, is extended to model growth using the
latent variable technology. The mean structure of the model
represents developmental change in student achievement. Restricted
covariance pattern models are proposed to model the
variance-covariance structure of the student achievements. The main
advantage of the extension is its ability to describe and explain the
type of time-heterogenous dependency between student achievements. An
efficient MCMC algorithm is given that can handle identification
rules and restricted parametric covariance structures. A
reparameterization technique is used, where unrestricted model
parameters are sampled and transformed to obtain MCMC samples under
the implied restrictions.The study is motivated by a large-scale
longitudinal research program of the Brazilian Federal government to
improve the teaching quality and general structure of schools for
primary education. It is shown that the growth in math achievement
can be accurately measured when accounting for complex dependencies
over grades using time-heterogenous covariances structures.</font></font></font></div><font size="3">
