At a time when most American states have embedded an initial certification test into their teacher preparation programs, Canadian educational authorities are faced with a choice: to test or not. One province, Ontario, has experimented with a standardized entry-to-the-profession testing instrument. For three years, 2002-04, teacher candidates were required to take an externally-administered examination, on top of the normal Bachelor of Education requirements, prior to certification. The results were decidedly mixed: politically viable, but pedagogically questionable. Now, the debate has been re-opened, as a new government seeks a more effective form of entry-level assessment for aspiring teachers.
