Rasch Measurement in Language Education Part 4:
Rasch Analysis Software Programs
James Sick, Ed.D. (J. F. Oberlin University, Tokyo)
[ p. 13 ]RUMM provides an all-graphical interface that uses familiar point and click set-up features, as found in modern statistical packages such as SPSS. It can output a wide range of multicolor charts and graphs, and fit a variety of Rasch models, including dichotomous, rating scale and partial credit models. It is also highly interactive, providing easy re-analysis following diagnosis of previous analyses. RUMM requires Windows XP or higher, with 1 gigabyte of RAM recommended.

[ p. 15 ]This is by no means a complete list. Many general Item Response Theory programs such as BILOG and MULTILOG can also do Rasch analysis. Although these programs lack the variable maps and other visual tools that Rasch analysts frequently employ, they may be an attractive alternative for researchers wanting to investigate both Rasch and 2 or 3 parameter IRT models. For some additional options, see the web store and features comparison tables at Assessment Systems (www.assess.com).
