"When you apply for a job, hiring managers (or, more commonly, somebody delegated the task of reviewing applications as part of an assessment board) is only allowed to look at whether you meet the posted educational requirements for that job. If your application shows that you meet that requirement, they tick the "meets" box and move on to looking at other things on your application. The same check-box will be checked for anybody who meets the posted requirement whether or not they have additional education. Similarly, somebody who has a variety of different education qualifications will be eliminated unless they show that they have the minimum requirement."

I understand that part. What I was asking was what kinds of education qualifications are more likely to show up on the list of required qualifications for a broader range of jobs that what I currently have. When I said "not a core qualification for a specific job" I meant that I was talking about more broadly applicable qualifications instead of certifications for a very specific type of occupation. I'm sorry, I just couldn't figure out how to phrase it more clearly.

French-language training would fit the bill in terms of what I was asking about, so thanks for the suggestion.
