OES does not have separate programs for special needs students, but the individualized attention and small class size can be beneficial to many students who have minor learning differences. Read more about Academic Support.

No. OES is a college preparatory school with a rigorous academic curriculum. We do not have programs for students with discipline, behavioral, or drug and alcohol related problems.

How does OES compare to other schools?

Excellent schools come in all shapes and sizes — public, independent, and parochial — and they serve different constituents and work toward different purposes. Ranking schools on a single scale does not celebrate or acknowledge these differences in schools. We feel strongly that schools should be measured, as our accreditation process does, on our ability to meet our mission, and to deliver our promise to families.
