A latent trait model for rating scales is used to analyze
responses to an attitude-to-school questionnaire as
part of an evaluation of projects operating in 10 Western
Australian schools under the Australian Priority
Schools Program. The invariance of item parameter
estimates over the 10 schools is examined, and variations
in item estimates from school to school are studied
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.
