I have a question!
"W apps and W matric"--what does the W stand for? Waitlist? Women? Similarly, in the "Woman or URM director" category (nice category!), the options are No/F/U. It takes a split second to realize what these mean.
Perhaps a little legend box--preferably right above the whole chart, since I believe upon opening the site, the instinct is to read top-down--might do the trick

And keeping the legends consistent between categories, if possible, would make this absolutely platinum-mine of a website even more wonderful (e.g. if the "W" is women, the "F" in the director-type category should also be W--ez pz reading!).
Further small-change design notes for ez pz reading (
this is coming from my design brain to improve the flow of the website--I don't mean to offend in any way!!!!!!):
On the home page, move the title! There's that red splotch where it says NIH--I love the concept of the blurred scientist doing lab work background, but I can't stop staring at the red and the fact that in THAT specific spot where it says "NIH" the black color is like 5-20% blending in, which contrasts with how perfect the rest of it looks...but then the blue might be in the way, which you avoided for the other pages...I see that not eclipsing the header translucently, which normally would have been the fix, is technically the better design choice because it provides necessary contrast to the secondary headers. Clearly you picked up on this. Maybe just move it somewhat to the right and below like you did for the other pages, that's a good placement. In an ideal world, I would want them in the middle, but given that shade of slightly-over-medium blue glove...we can't have black text there, can we...eugh. Maybe just change the background image to one that doesn't provide so many issues LOL
Unbalanced white space--this is just for the home page where you provide links to data, caveats, and voting information. I see that you're trying to balance these headers with the textbox information below--maybe just center everything. That way, even if there's lots of white space, it's balanced, and isn't so jarring to the eye.
Ensure the headers are a consistent font-size and color, perhaps excepting the home page due to its significance in the site. Otherwise, strange design-heads like me go for a mental loop-de-loop! Actually, make sure everything in the same "page-element-type" group is consistent across pages.
The blue tab-box is white for the match-list page with different (probably prior-version) font sizes. This is likely a very quick fix. Also, on this page, the white textboxes are no longer translucent! In fact, your %-transparency is different for each page!
Finally, the home page and feedback page's secondary headers respect edges of the textbox and give them some breathing room. The match list and resources page's secondary headers do not provide breathing room. Give them some, like you did for the other pages, and suddenly beautiful, consistent, breathable harmony has been regained...ooh la la...
Again, thank you for providing such an amazing resource. I'm a current applicant and this is awesome.
P.S. if you want me to make these fixes myself, I humbly volunteer to do so...
