jMetrik is a free and open source software application for psychometrics. It features a user friendly interface, an integrated database, and methods for applying classical and modern psychometrics. The purpose of the short course is to familiarize participants with jMetrik and its use in scale development and applied testing programs. All relevant measurement theory will be covered in the short course with emphasis on its implementation in jMetrik. At the end of the short course, participants will be proficient in using jMetrik to analyze test data.
The short course will be conducted by Patrick Meyer, Ph.D., Assistant Professor at the University of Virginia and developer of jMetrik.
jMetrik 3.0 Beta
Version 3 is a major revision of jMetrik that includes changes to its underlying structure, database functionality, and graphical user interface. It also includes enhancements to existing psychometric procedures and the addition of several new methods. Some of the most notable changes include the capability to:
- Create new tables by selecting subsets of variables
- Create new tables by selecting subsets of examinees
- Save item analysis output to a new table in the database
- Save DIF analysis output to a new table in the database
- Save graphs to disk as png or jpg files
- Automatically save multiple characteristic curve plots to disk as jpg files
- Automatically generate item scoring commands from the interface
- Create your own matching score for a DIF analysis
- Create your own latent trait estimate for nonparametric characteristic curves
- Produce nonparametric curves more rapidly with less drain on system resources
Accompanying these enhancements are new features for item response theory linking and equating. jMetrik now provides the capability of estimating linking coefficients with mixed format tests using any combination of Rasch, two parameter logistic, three parameter logistic, partial credit, generalized partial credit, or graded response models. It also allows users to conduct IRT true score equating.

Remote webinar participation allows you to join the short course from your home or office. A web browser and internet access are the only requirements for the webinar. The short course will be conducted for two hours a day for five days. All participants will have access to video recorded shortcourse sessions for up to two months after the shortcourse.
International Short Course Participants
Participants will have additional options for participation if their time zone makes it difficult to participate from 1:00-3:00 p.m. Eastern Standard Time (UTC/GMT minus 5 hours) on the days of the short course. These options are designed to allow participants from places like Australia, India, Malaysia, and Saudi Arabia to join the shortcourse. Video tapes of each session will be available soon after it is complete. You may view these video tapes at any time and send us questions. We will also schedule special sessions at times that make it easier for you to participate in person. You may use these special sessions to ask questions and see additional live demonstrations. We will offer the special sessions during the week of the short course. Please contact us to make arrangements for a special session. We will do our best to accommodate all participants.
