Abstract
A latent trait model for rating scales is used to ana lyze responses to an attitude-to-school questionnaire as part of an evaluation of projects operating in 10 West ern Australian schools under the Australian Priority Schools Program. The invariance of item parameter estimates over the 10 schools is examined, and varia tions in item estimates from school to school are stud ied in the light of the different projects operating in these schools. Results show how the investigation of items that do not retain their difficulties from group to group can provide valuable insight into the ways in which calibration groups differ.
