The HGSE Grant is need-based and the maximum amount (as of 2016-2017) is $14k. Unfortunately, many people are not offered any financial aid besides federal loans. Here is a spreadsheet that I made last year to catalog financial aid profiles. I was initially offered $10k HGSE Grant and was able to get Federal Work Study by going to the Financial Aid Office and requesting it. Also, the second sheet of this spreadsheet has admittance profiles.
Current HGSE student here. Just wanted to confirm that we are being recruited for a phonathon to congratulate accepted students on March 7th @ 5:30 pm. I think it's safe to say that y'all can expect admission decisions before then!
