In the spring of 2002 the Ontario College of Teachers began a research project in order to foster awareness of the "Standards of Practice" for the 187 000 teachers in the province. Case work, in which 18 teachers representative of the College's membership wrote narratives describing their professional dilemmas, was the methodology chosen. Through reflection and collaborative group work these practitioners co-created a set of cases, mapping them back to the standards in order to ascertain how the standards had been embedded or absent from their daily practice. To validate the effectiveness of this method, we used the cases in pre-service, in-service, principal and supervisory personnel venues. We also recorded the impact of the 'case institute' in a focus group session with the original writers. Augmented by commentaries from internationally known teacher educators, this text will be sent to all provincial school boards as part of a resource kit to educate teachers about the standards of practice.
