>> The format will consist of four self-contained units. The units are:

>> Rasch Analyses including Running WINSTEPS. The material covered is these
>> units provide an overview of material that would normally be covered in a

>> Registration includes the one-day workshop, a copy of Introduction to Rasch
>> Measurement (698 pages), and Rasch Measurement: Advanced and Specialized
>> Applications (470 pages). See www.jampress.org for more details on these
>> publications.  The cost of the workshop is $200 for professionals and $140

>> Audience: Anyone interested in learning about the practical aspects of Rasch
>> measurement. Previous training in measurement is strongly recommended, but
>> not necessary.
