Iteman is a Windows application that provides item and test analysis reports using classical test theory. It has a graphical user interface organized into tabs for settings, files, input format, scoring options, and output options. Key advantages include adding item quantile plots and handling of pretest items. The item control file specifies item-level information in five columns: item ID, options, keys, domain, and inclusion status. Iteman's interface divides tasks into tabs for specifying input/output files and options for scoring, scaling, and report output.

2. ITEMAN
• Iteman is a Windows application 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 and
improve the quality of test items by examining their psychometric
characteristics.
• Iteman has a friendly graphical user interface (GUI) that makes it easy
to run the program.
• The GUI is organized into five tabs: Settings, Files, Input Format,
Scoring Options, and Output Options.

3. Advantage
• The most important advantage is the addition of graphics. It is now
possible to produce an item quantile plot for each item. Moreover,
you control the number of points in the plot.
• Iteman 4 is able to handle pretest (trial or unscored) items—items
that are not included in the final score but for which statistics are still
desired.
• More statistics are calculated, including the alpha (KR-20) reliability
coefficient with each item deleted.

4. The Item Control File
• Iteman 4 provides the specifications as a separate Item
Control File. This makes it easier to produce, as well
as allows for the handling of a greater amount of
information.

5. Step of Item Control File
There are five columns of information in the control file for each item.
Begin each item on a new line.
1. Item ID: enter items statement or code of statement
2. Enter all Options:
• Correct answer(s) as A,B,C,D or 1,2,3,4 for standard multiple choice
questions.
• Dichotomous: Yes/No, 100% or 0%

6. Continue….
3. Enter keys:
For multiple-choice data that are already scored (converted to 0
or 1), the number of options is 2. However, we recommend
recoding so that 1=correct and 2=incorrect
4. Domain or set standard for content area
5. Inclusion status:
• Y = Yes (included in the analysis)
• N = No (not included)

7. Iteman’s interface
• Iteman’s interface is divided into four tabs.
• The Files tab specifies the files to be used:
1. The Input Format tab tells Iteman what to expect in your input. Data
Matrix to indicate skipped these items and not use for test.
2. The Scoring Options tab enables you to perform scaled scoring and to
perform dichotomous classification.
3. The Output Options tab specifies options for the output.

9. • Create/Run Multiple Runs File
If you would like to interactively create a Multiple Runs File (MRF)
you can do so by clicking opening the File menu and selecting Create a
Multiple Runs File. In addition, you can run a previously saved MRF by
clicking “Run a Saved Multiple Runs File”.
• Save an Options File: Control + S
• Save the Program Defaults
This will overwrite the existing program defaults with the changes
made during the current run of the program. These changes will appear
the next time the program is loaded.
