<div style="margin-bottom:0cm" lang="en-US"><b>Resumo:</b></div>
<div style="margin-bottom:0cm" align="justify" lang="en-US">
A multistage test (MST) is a computer-based assessment that may be
thought of as a compromise between a linear test and a
computer-adaptive test (CAT). As such, MSTs may be vulnerable to at
least some of the major security threats associated with each of
these types of test (e.g., copying for linear tests and item
pre-knowledge for CATs). The degree of vulnerability of any
particular MST to these threats, as well as others, will depend
(among other things) on details of the MST assembly and
administration design. To supplement these preventative measures,
routine statistical monitoring of response and timing data for items,
modules and tests, as well as the screening of performance of
individual test takers and clusters of test takers, is essential.</div>
<div style="margin-bottom:0cm" align="justify" lang="en-US">
For monitoring and screening procedures to be effective, it is
critical that statistical baselines be developed for the different
characteristics of the data that are being monitored. Since an MST
has a different structure than either a linear test or a CAT, it is
reasonable to expect that test takers’ behavior for MSTs will
differ systematically from behavior observed for either linear tests
or for CATs. In this presentation I discuss two concrete analyzes,
one that identifies people who are outliers and one that identifies
items that are outliers. For the first approach we use the scores
from the variable section of the test (and make use of the MST
design) to produce an expected score. For the second approach I
present the use of traditional quality control tools such as CUSUM
charts to identify items that have been exposed. What we are looking
for are data patterns that deviate substantially from our baselines
in ways that are consistent with what would be expected from behavior
that may lead to invalid scores.
