West Point tends to be (historically at least) more flexible with their LOA's than the other academies, which (especially AF) require you to have everything in (other than Dodmerb and the nomination) before even considering you for one. Two years ago (2014), when my oldest son was applying, he knew several people who'd gotten an "LOA of an LOA"
- based totally on what they submitted for SLS. They received an email telling them that IF everything was as portrayed once submitted officially (ie grades, SAT scores, etc.), that they would then get an official LOA. Those seemed to be out in mid-July sometime.
Last year (2015), I didn't see any of those but still saw several that went out without the CFA considered in them - so passing that was also a requirement. I don't know what the standard is for this year, but some candidates are flagged already (at least in my region) as potentially receiving LOA's (once the guidance is official). Some of them don't have everything in yet - seems like things like SAT scores (obviously), transcripts and activity records are far more important than the one outstanding teacher recommendation. Whether something like that would keep the LOA from being issued once they do become available, I'm not certain. It really sounds like they're cutting back on the number of LOA's this year compared to last, and last year's were far lower than the previous year. Bottom line - get everything in as soon as possible to have the best possible shot at one!
