Iteman™ 4 is a software program designed to provide detailed item and test analysis
reports using classical test theory (CTT). The purpose of these reports is to help testing
programs evaluate the quality of test items, and tests as a whole, by examining
their psychometric characteristics. Output is RTF format, allowing you to type/paste
in item texts and comments and deliver a comprehensive report to stakeholders or content experts.
Iteman™ 4 (currently version 4.1) is distinguished by its user-friendly interface that
makes it easy to run the program, even if you are not an expert in psychometrics.
Teachers, school administrators, certification managers, training coordinators, and
instructional designers can all use Iteman™ 4 to produce professional psychometric reports.
What’s New in Iteman™ 4
Iteman™ 4 offers several substantial improvements from the previous version, ITEMAN™ 3.6:
The most important advantage is the addition of graphics. It is now possible to produce
an item quantile plot for each item.
Iteman™ 4 is able to handle pretest (trial or unscored) items, items that are not
included in the final score but where statistics are still desired.
More statistics are calculated, including the alpha (KR-20) reliability coefficient
with each item deleted, and subgroup P (proportion correct) statistics.
Instead of simple ASCII text files, the output is now rich text file (RTF) format laid
out as a formal report, and also in a comma-separated value (CSV) format
that is able to be manipulated (sorted, highlighted, etc.) in spreadsheet software.
It additionally produces a CSV file of examinee scores and subscores.
Scaled scoring can be applied, so that Iteman 4 can be used to score sets of examinees
in more testing programs and provide scores on any linearly transformed scale.
Items can be analyzed relative to an external score rather than the total score on a test.
The maximum number of items that can be analyzed has been increased to 10,000,
with no limit on the number of examinees.
A “batch” type of capability, using a “multiple runs file” has been added to allow you
to run multiple data sets without having to use the graphic user interface for each run.
Iteman 4 can analyze both dichotomous (correct/incorrect) and polytomous (ratign
scale or partial credit) data, including tests that are a mix of both item types.
