Learners Chess Ratings Lists
In the Fall of 2019, Learners Chess developed an internal method of tracking players’ game results and then “rating” the game results on a regular basis.
Tracking ratings is a great way for chess learners to track their relative improvement against that of their peers.
We currently have two lists that we publish:
- A simple rating list that includes each player’s school name. During our school programs, this list will be updated at least weekly.
- A more interactive and detailed list with links to each player’s in depth rating profile, which includes a line graph of the player’s overall progress and a list of all the player’s game history. Also, on this list is a cross table of standings for each school represented on our rating lists. This list will up updated at least monthly.
About these ratings:
- Learners’ students may play rated games in their clubs, at camps, at Community Chess nights, or in Learners’ tournaments.
- Learners chess coaches who are overseeing their clubs or camps will report game results.
- These lists will be updated regularly. Typically, we will have new ratings published on Tuesdays, especially when school programs are ongoing and after tournaments.
- Only players who have played a rated game in the past 91 days will be listed.
- Typically a player’s rating is not very accurate until the player has played rated games against 25 different opponents, all who have semi established ratings, over the course of a few months.
- These lists will get more and more accurate as more students play games against each other, especially after tournaments and other events that pair students from different schools against each other.
- How are they calculated: We are using a program called “The Chess Ranking Assistant,” which calculates ratings based on a player’s initial rating and the ratings of the opponents played. If two equally rated players play a match, their ratings will change by the same amount but in opposite directions. If they draw, their rating will not change. If a very high rated player wins over a much lower rated player, the ratings of each will only change a little. If the lower rated player wins, the higher rated player will lose more points than she/ he would have gained for winning and the lower rated winning player will gain those points. More specifically: These ratings are calculated using the Glicko rating system.

- As with all aspects of our organization, we will regularly work to improve the quality of these lists.
