ChessKid.com maintains both a chess rating and a puzzles rating for each account. Ratings on the site are independent from any official rating system. However, the more a student plays on the site, the more his/her rating should approximate his/her real rating.
​

Chess ratings start at 800. Your rating will go up and down as you win or lose games. How much your rating changes each time you win or lose a game depends on what your current rating is, what your opponent's rating is, and how many games each of you has completed.
​

As you play more games, your rating won’t change as dramatically as it did in the beginning. Also,if you resign a game before moving (cancel the game because you’ve decided you don’t want to play), your rating will drop!
​

Puzzle ratings also start at 800, and will change as you continue to solve puzzles. Solve a puzzle correctly & you’ll receive a harder puzzle on the next turn!
