<p>Lori,
Miami Ohio is accredited – but the Masters degree not the undergrad degree (It is a 4+2 program). I’m not sure about double majors, but they REQUIRE a concentration in an area not related to the major with the thematic sequence. They also require a lot of LAC type courses with their Miami Plan, which you can sometimes focus into a type of concentration.
It is not ranked up there with the other schools, but seems to have a very solid program, especially for anyone who is not 100% sure about architecture. While they stress a LAC education, there will still be 4 full years of studio at the undergrad level, which will help with assembling a portfolio for grad school admissions.</p>
