So...this is probably pretty much useless information, but I thought I'd share it anyway since it's interesting.
In 2003, the HGSE masters program acceptance rate was 54% (761/1404).
In 2003, the HGSE EdD (there was no PhD) program acceptance rate was 13% (79/592).
I tried using the internet archives to see if HGSE has ever posted acceptance rates, and unfortunately 2003 was the last time they posted them. From 2004 on they were removed. But in any event, it's interesting. In the years prior, the masters acceptance rate fluctuated between 53-65% and the PhD acceptance rate held steady at 15%.
Who knows what it is now though...
