Description

It has been a difficult task for teachers to compare the abilities of students from different grades or levels using traditional testing theory (TTT) because all students must take a common test that includes items covering the entire range of abilities. However, by using Rasch measurement theory (RMT), it is possible to give graded forms of the test to each group of students by including some overlapping items. This study provides a brief introduction to RMT followed by a demonstration of an application of the theory to measure abilities of students from different grades in junior high schools. The process of equating three different English achievement test forms, one for each grade administered to a total of 900 junior high school students is described. A list of useful resources on RMT is also provided in the appendix.
