Setting pre-requisites based on concepts; not courses

I wish we would revise all of our courses to identify the competencies that are being taught/learned in each course in order to pin-point the pre-requisite for the next course. Therefore, when testing a student that falls into DEVmath for different concepts than those needed for accounting we can determine that s/he can take accounting because they meet the competencies needed for accounting even though they have not mastered all of the ones needed to be above DEVmath. OR just teach them the competencies that they are lacking.
