When seeking entry to a profession or employment in Ontario, Canada, internationally trained professionals may face multiple challenges. One of the most serious challenges to labour market success, as identified by immigrants themselves, is a lack of recognition of the academic credentials earned outside of Canada. International credential recognition is a very complex process that depends on many factors, often combining credential evaluation with other processes such as language, competency and skills assessments. The purpose of this guide is to create a Best Documentation Practice Model to help those evaluating credentials ensure that their organizations or institutions documentation practices are transparent, objective, fair and consistent. The strategies and processes described in the guide apply to documents being received from any source; however the particular focus is on international credentials, for example credentials issued by non-Canadian institutions. The Best Documentation Practices Guide will: (1) Describe how to obtain authentic documents; (2) Suggest documentation requirements criteria; (3) Provide definitions to the terms used in documentation practices; and (4) Suggest alternatives to situations where required documents are not available. [The Best Documentation Practices Guide was originally prepared in April 2010 by the Documentation Standards Project Working Group with funding from the Ontario Ministry of Citizenship and Immigration.]
