"Once all applications have been reviewed, HGSE will invite selected Ed.L.D. applicants to campus for a day of required interviews (both individual and group) with members of the admissions committee. Interviews will take place in late February 2016."
I think that the similarities between accepted and rejected based on these metrics point strongly to the fact that SOP and LOR mean a lot. I once heard a statistic that MIT could have a class every year of students with perfect scores on SATs... Harvard's in a similar boat.
