HeadFirst out of Washington runs a national academic showcase (Jul in Ca, aug in va and nov in fl). excellent showcase if you are looking for highly academic schools. all the Ivy's attend as well as many other D1 schools (Villanova, W&M, Georgetown, Maryland, Richmond, Davidson, Wofford, UVA, UMBC, Lehigh, Lafayette, Bucknell, Army, Navy, Duke, Stanford, Fordham, St Joe's, St John's and others)and many very good D3 programs. We attended several showcases over the past 1.5 years and this was by far the most productive in terms of interest from the schools my son was interested in, both D1 and D3. Good luck.
