Introduction
What is program iteman?
Program iteman is a software platform that automates the creation of item analysis reports based on classical test theory. Classical test theory (CTT) is a set of methods and assumptions for measuring psychological traits or abilities using tests or assessments. CTT provides statistics such as difficulty, discrimination, reliability, validity, and standard error of measurement for tests and items. Item analysis is the process of evaluating how well each item performs on a test based on these statistics.
Program iteman can save you time and money by generating detailed reports in Microsoft Word with embedded tables, graphs, and narratives. You can easily share these reports with subject matter experts or stakeholders to review and improve your tests. Program iteman also offers features such as differential item functioning (DIF), mastery (cutscore) analysis, scaled scoring, automated flagging of poorly performing items, collusion (cheating) analysis, and more.
What is a .rar file?
A .rar file is a compressed file format that can store multiple files or folders in a smaller size. This can help you save disk space, reduce download time, and protect your files from unauthorized access. A .rar file can be created and opened by a software program called WinRAR, which we will discuss in the next section.
What is WinRAR?
WinRAR is a software program that can create and extract compressed files in various formats, such as .rar, .zip, .7z, .tar, .gz, and more. WinRAR is one of the most popular and widely used compression tools in the world, with over 500 million users. WinRAR offers features such as encryption, password protection, split archives, recovery records, self-extracting archives, and more.
WinRAR is compatible with Windows, Linux, Mac OS, Android, and other operating systems. You can download WinRAR from its official website or from other trusted sources. WinRAR is not a free software, but it offers a 40-day trial period for you to test its functionality. After the trial period expires, you can either purchase a license or continue using WinRAR with some limitations.

How to Use Program Iteman for Test and Item Analysis
Now that you have downloaded and installed program iteman on your PC, you might be wondering how to use it for test and item analysis. Here are the steps to follow:
Prepare your input files
The first step is to prepare your input files for analysis. Program iteman requires two types of input files: a data file and a key file. The data file contains the responses of your examinees or participants to your test or assessment. The key file contains the correct answers or scoring information for your test or assessment.
The data file and the key file must be in plain text format (.txt) with comma-separated values (CSV). The data file must have one row per examinee or participant, and one column per item. The values in each cell must be either 0 or 1, indicating whether the response was incorrect or correct, respectively. The key file must have one row with one column per item. The values in each cell must be either 0 or 1, indicating whether the answer was incorrect or correct, respectively.
For example, suppose you have a test with 10 items and 5 examinees or participants. Your data file might look something like this:
0,1,1,0,1,0,1,0,0,1 1,0,1,1,0,1,0,1,0,0 0,0,0,1,1,1,1,0,1,0 1,1,0,0,0,0,1,1,1,1 0,1,1,0,0,1,0,0,0
Your key file might look something like this:
1,1,1,0 0,1,0,1,1,0,1
You can create these files using any text editor or spreadsheet program, such as Notepad or Excel. You need to save these files in a folder on your PC where you can easily access them.
Specify your analysis options
The next step is to specify your analysis options for program iteman. You can do this by launching the program and clicking on the "Options" button on the main window. This will open a dialog box where you can choose various settings for your analysis, such as:
- The name and location of your data file and key file - The number of items and examinees or participants in your test or assessment - The type of test or assessment (multiple choice, true/false, etc.) - The scoring method (number correct, proportion correct, etc.) - The output format (Microsoft Word, HTML, etc.) - The output options (tables, graphs, narratives, etc.) - The analysis options (difficulty, discrimination, reliability, validity, DIF, mastery, scaled scoring, flagging, collusion, etc.) You can also customize the appearance and content of your output report by changing the fonts, colors, titles, labels, and descriptions of your tables and graphs. You can also add your own logo and header to the report. You can save your analysis options as a profile for future use or load a previously saved profile.
Run the analysis
The third step is to run the analysis using program iteman. You can do this by clicking on the "Run" button on the main window. This will start the analysis process and show you a progress bar indicating how much time is left. Depending on the size and complexity of your data and analysis options, the analysis may take from a few seconds to a few minutes.
When the analysis is complete, program iteman will automatically generate an output report in Microsoft Word with embedded tables, graphs, and narratives. You can view the report on your screen or save it on your PC. You can also print or email the report to others.
Review the output report
The final step is to review the output report produced by program iteman. The output report will contain various sections with different types of information and statistics for your test and items. Some of the sections are:
- Summary: This section provides an overview of your test and items, such as the number of items and examinees or participants, the mean and standard deviation of scores, the reliability coefficient, and the validity coefficient. - Item Statistics: This section provides detailed statistics for each item on your test or assessment, such as the difficulty index (p-value), the discrimination index (point-biserial correlation), the distractor analysis (option frequency), the standard error of measurement (SEM), the confidence intervals (CI), and more. - Test Statistics: This section provides comprehensive statistics for your test or assessment as a whole, such as the reliability coefficients (Cronbach's alpha, KR-20, KR-21, split-half reliability, test-retest reliability, parallel forms reliability), the validity coefficients (content validity ratio, criterion-related validity coefficient), the standard error of measurement (SEM), the confidence intervals (CI), and more. - Graphs: This section provides graphical representations of some of the statistics for your test and items, such as histograms of scores and p-values, scatterplots of scores and point-biserial correlations, - Item Response Theory: This section provides information and statistics for your test and items based on item response theory (IRT) models and methods, such as the item characteristic curves (ICC), the item information functions (IIF), the test information function (TIF), the item parameter estimates (difficulty, discrimination, guessing), the ability parameter estimates (theta), and more. - Differential Item Functioning: This section provides analysis and results for detecting and measuring differential item functioning (DIF) for your test and items. DIF is a phenomenon where an item performs differently for different groups of examinees or participants based on factors such as gender, ethnicity, language, or disability. Program iteman can perform DIF analysis using methods such as Mantel-Haenszel, logistic regression, or IRT. - Mastery Analysis: This section provides analysis and results for determining and applying mastery (cutscore) levels for your test or assessment. Mastery levels are the minimum scores or abilities required to demonstrate proficiency or competence in a certain domain or skill. Program iteman can perform mastery analysis using methods such as Angoff, Nedelsky, Ebel, Bookmark, Contrasting Groups, or IRT. - Scaled Scoring: This section provides analysis and results for converting raw scores to scaled scores for your test or assessment. Scaled scores are standardized scores that have a fixed mean and standard deviation across different forms or versions of a test or assessment. Program iteman can perform scaled scoring using methods such as linear transformation, equipercentile equating, or IRT. - Flagging: This section provides analysis and results for identifying and flagging any poorly performing items that may affect the quality of your test or assessment. Program iteman can flag items based on criteria such as difficulty, discrimination, distractor effectiveness, reliability, validity, DIF, or IRT. - Collusion Analysis: This section provides analysis and results for detecting and measuring collusion (cheating) among examinees or participants on your test or assessment. Program iteman can perform collusion analysis using methods such as K-index, S-index, G-index, Q-index, or IRT. You can review the output report to understand and interpret the results of your analysis. You can also use the output report to improve your test or assessment by revising, deleting, or adding items based on the feedback and recommendations provided by program iteman.
