I saw a link to Epsilon Camp
http://www.epsiloncamp.org/
and it got me thinking.

What "elite" math camps are there (for what age/grade ranges)?

I'm thinking about camps that genuinely cater to the top 0.1% (or thereabouts) in math, not just something like the top 5%.

So the general question is, what is the list of such math camps in the USA (or North America)?

More specifically to our situation, our DS7 is somewhere in the top 0.1% in math, but we're not exactly sure where. We'd want him to be with genuine peers. We homeschool and have one stay at home parent (and the other often working at home too) so we certainly don't need "summer camp as child care now that school's out" at all. Also we both have math PhDs and could probably teach DS7 anything he'd see at Epsilon Camp (and maybe the "older camps"). The price of Epsilon Camp is quite a shock. For tuition, room and board (including required accompanting adult) and transport it would be more than $4,000 for only two weeks. We're frugal (we spend about zero on education, have one 12yo car etc.) and generally balk at such an expense, but if it is truly worth it, we can do it.

It would be worth it if it were to be a truly incredible life-altering experience for DS. But would it be? DS, though not shy, and a very nice kid, is a bit socially awkward and has basically never really connected with another child, except his younger siblings, due in part to being so different and not hiding it. Maybe he would find true peers that he could really connect with. That would be the real purpose of going. And to discuss mathematics with a wider group of children and adults outside the family.

Anyone have opinions, or feedback, about Epsilon Camp specifically, or about math summer camps generally?

Another question is about the Epsilon Camp Admission Criteria.

DS easily exceeds the Achievement Test cutoffs by a very wide margin, and would be otherwise ready with the math background (maybe waiting til 2015 to be solid with the Algebra I prerequisite) but he does not have a qualifying IQ score due to certain subtests being markedly lower than the rest. Does anyone know if they are strict with these cutoffs, or do they use some "common sense" when a child clearly easily exceeds all their mathematical requirements, but falls short on parts of an IQ test that really shouldn't matter when it comes to mathematical aptitude.

Also are there any "elite" (top 0.1%) math summer camps, that are not so expensive (and how do you get in)?
