Abstract
Several methods for optimal test construction
from item banks have recently been proposed using
information functions. The main problem with
these methods is the large amount of time required
to identify an optimal test. In this paper, a new
method is presented for the Rasch model that
considers groups of interchangeable items, instead
of individual items. The process of item clustering
is described, the cluster-based test construction
model is outlined, and the computational procedure
and results are given. Results indicate that
this method produces accurate results in small
amounts of time. Index terms: information functions,
item banking, item response theory, linear
programming, test construction.
