Applying the Rasch model in practice
We continue to receive requests for the publication Applying the Rasch model to psycho-social measurement: A practical approach. (Wu, M. and Adams, R., 2007). The document was removed from this site in 2012 as some chapters were considered for use in a forthcoming Item Response Theory book authored by Margaret Wu. We are pleased to announce that as of July 2014 we are able to provide this resource once again to users free of charge. It can be downloaded here. For academic publications, the reference is: Wu, M. and Adams, R. (2007). Applying the Rasch model to psycho-social measurement: A practical approach. Melbourne, Australia: Educational Measurement Solutions.
