What is meant by “not necessarily within a post-secondary or degree program in the required specialization”?
The courses for the specialization do not have to be taken within a specific program. The courses may have been taken while completing a post-secondary education, or separately at a later date, as long as they were taken in a recognized educational institution (for the FI 1 level) or in a recognized university (for FI 2 and above). It is up to the manager to determine whether the candidate has an acceptable/significant number of courses to constitute a specialization for the position being staffed.
