2021 year-end NTRP ratings are being calculated, when will they be published?

2021 USTA League Nationals are over, and that means 2021 year-end NTRP ratings are now being calculated.  I've confirmed the cut-off date for matches this year was November 14th so everything should be in and calculations can commence.

I don't know the specifics of the process the USTA goes through at year-end, but believe that National does the calculations, taking the final dynamic rating for all players and then doing their year-end calculations to factor in what happened at Nationals and filter that back down through the sections.  I understand sections/districts may be given preliminary ratings to review, presumably to look for gross errors or things that seem out of whack so those can be researched and a determination made on if/how to correct or adjust things.

So when will it all be done and ratings published?  The date that seems to be out there this year is December 1st and this would be consistent with past years where the ratings generally come out the week after Thanksgiving and 12/1 would be the Wednesday after Thanksgiving this year.  Could they come out a little earlier or later than that date?  Sure, but my guess is the ratings will begin to show up late the night before, or right around 12:00 AM ET on 12/1.

It will be interesting to see what happens this time around, I've already written a bit about what might happen and why, and I'll likely write some more using my ratings as a predictor of what could happen.  But this is an odd year with a 2-year rating period and more matches played than normal, so it might not exactly fit the profile of prior years.

If you can't wait the two weeks for ratings to come out, or are just interested in seeing a detailed breakdown of how you did in 2020/2021, I continue to do my Estimated Dynamic NTRP Rating Reports that uses the ratings I calculate that give what has historically been a pretty accurate correlation with what the USTA publishes.  If you are interested, contact me at ratings@teravation.net.

  1. I thought the cutoff date is usually the last weekend for adult league nationals (mixed excluded), so that would've been October 31. Why do you think they included the mixed nationals this year through November 14?
