A Rasch Rating Scale Modeling Software Using the Copy-and-Paste Approach
RaschOnline is a web-based application for performing Rasch Rating Scale Modeling (RSM) directly in a browser.
It allows users to copy-and-paste data into an input box, execute Rasch model analysis, and visualize item–person statistics such as Wright maps, KIDMAPs, and fit plots.
The system is implemented in Classic ASP and designed for educational and clinical psychometrics.
- Copy-and-paste data entry (no file upload required)
- Automatic detection of item and person fields
- Rasch Rating Scale Model computation
- Output of item/person fit, reliability, and Wright/KIDMAP graphs
- Classic ASP backend (no installation of R or external packages required)
- Runs locally under IIS
