Scoring
		How do you keep a student from retaking a test, thereby overwriting their score?
		Some vendors only handle a simple number 0-100 (no decimal support). The issue is, without decimal support, how do you grade a test that has multiple matching questions?
	Where is data placed for transfer?
		Can use both objectives and interactions to store results of one test.
		Each vendor may interpret differently
	Assignable Units
		An assignable unit is the smallest piece of a course that can be served
		Each time the student changes assignable units, the server must be involved, this may lead to slow courses being served to students.
		Note: ReadyGo interprets an AU as either a chapter or a whole course
	Compliance:
		Many courses have been certified as compliant; however on further investigation, these courses do not have any tests or tracking.
