Where I work, we are allowed a 5% ratio of GED applicants. That is 1 for 20. By the MPPM, a tier 2 (GED) applicant has to score higher on the the ASVAB to get less. That is the nature of the beast. The only way around it is that if you have 15 college credits in addition to a GED, then you are considered Tier 1 (high school grad).
