A Guide On Different Chess Rating Systems – FIDE, USCF, And ECF

There are three primary rating systems for chess: FIDE, USCF, and ECF.

The World Chess Federation employs the FIDE rating system, while the United States Chess Federation uses the USCF rating system. Meanwhile, the English Chess Federation makes use of the ECF rating system.

Each rating system comes with its own set of regulations, which we will examine separately.

But first, let’s begin with the basics of what ratings are in chess.

What Is A Chess Rating?

A chess rating represents a numerical gauge of a player’s proficiency in the game. It derives from the player’s performance in rated games and is generated by means of a mathematical formula.

Irrespective of whether it’s FIDE, USCF, or ECF, all chess rating systems operate on this principle. The primary variance among them lies in the formula used to compute rating points.

What Rating System Is Used By Fide To Rank Chess Players?

The World Chess Federation (FIDE) utilizes its own rating system based on the ELO method, which is a system for determining the relative skill levels of players.

It was created in 1948 by Arpad Elo. The system is based on a player’s results in tournaments.

According to their system, tournaments are divided into categories of a narrow average rating of the players, e.g. category 1 is for an average rating of 2251-2275, category 2 is 2276-2300, and so on.

Women’s tournaments are currently operating at 200 points lower than the men’s category.

Below is a guide video on different levels in FIDE ratings:

How To Get A FIDE Rating?

To get a FIDE rating, the following criteria must be met:

  1. Take part in a FIDE-rated tournament.
  2. Engage in a game against a minimum of 5 FIDE-rated players.
  3. Score at least half a point i.e. a draw against a FIDE rated player.
  4. Suppose you have played against 5 FIDE-rated opponents, but unfortunately, you lost 4 games, and the 5th player defaulted, meaning your opponent forfeited without making a move. In this scenario, you will not receive a FIDE rating. It is essential that opponent plays at least a move before resigning in order for you to become eligible for a FIDE rating.

Upon satisfying all of these requirements, you will receive a FIDE rating. It is essential to note that a FIDE rating can solely be obtained via an over-the-board tournament, as no ratings are assigned to online tournaments.

It is worth noting that the rating earned after 5 to 19 official FIDE-rated games is a provisional rating.

Only once an individual completes 20 FIDE-rated games will their official rating appear on the FIDE website.

What Are The USCF Ratings?

The USCF rating system is a mechanism utilized to evaluate chess players in the United States, created by the United States Chess Federation in 1950. While the USCF rating system, like the FIDE rating system, is based on the ELO system, there are variations in the formula utilized.

Following are the two formulas of how the USCF rating system works:

USCF = 720 + (0.625 * FIDE) if FIDE < 2000

USCF = -350 + (1.16 * FIDE) if FIDE >=2000

Below is a comparison table exhibiting USCF vs FIDE ratings:

How To Get USCF Rating?

To obtain a USCF rating, one must first play 20 games in an unrated USCF tournament before becoming eligible to participate in a rated USCF tournament.

Once a player has completed 20 unrated games, they can play in a rated game and receive an official USCF rating.

This system is good because when an unrated player enters a tournament, other players do not know their skill level. The requirement of 20 unrated games helps alert other players that the unrated player may be a strong opponent.

And that’s perfectly acceptable because if an unrated player is skilled, they can potentially upset the rating of a rated player who has obtained their rating after playing numerous games.

What Are The ECF Ratings?

The ECF chess ratings system is used to rank chess players in the United Kingdom, and it is calculated by the English Chess Federation (ECF).

These ratings are employed to determine player eligibility for tournaments and matches. The system was devised by Richard W. B. Clarke in 1958.

The primary difference between the ECF rating system and others is that rating points are not immediately effective for every game won, lost, or drawn.

Instead, they use a system that generates points on a cycle of 30 games.

In comparison to the USCF system of ELO, the ECF ratings system employs a simple formula.

An ECF rating is equivalent to an ELO rating multiplied by 7.5 and then adding 700.

Thus, a rating of 100 ECF corresponds to approximately 1450 ELO, while a rating of 200 ECF corresponds to about 2200 ELO.

How To Get An ECF Chess Rating?

The official procedure for obtaining an ECF chess rating can be found on the English Chess Federation’s website here.

The ECF uses a monthly rating system and assigns dummy ratings to new players whose actual strength is unknown.

This prevents a strong player’s rating from being negatively affected by a positive result from an unrated player who may be stronger than anticipated.

What Is A Provisional Rating?

The provisional rating is a scenario where a tournament game is rated for one player, but not for another.

The logic is simple: let’s say you encounter a 1200-rated player in a tournament.

This player could be the best player in the world, the worst, or anywhere in between, and no one knows their actual strength.

The provisional rating is given to the player after the game, but it is only temporary until the player has completed at least 20 games.

What Is A Performance Rating?

Based on the opponents that a player faces in a tournament, their performance rating can be calculated to distinguish between two players with the same score.

For instance, let’s consider Player A and Player B, both of whom played five games in a tournament, won three and lost two games.

However, their performance rating may differ because Player A won a game against a player who had won four games in the tournament, while Player B’s victories were only against players who won three or fewer games.

Therefore, Player A will receive a higher performance rating and finish ahead of Player B in the tournament standings due to a superior overall performance score.

How Often Are The Chess Ratings Updated?

In online chess, you get a new rating immediately after finishing the game. But in FIDE, USCF, or ECF-rated tournaments, it takes time to update ratings.

Each of them has its specific rules to update the ratings. ECF updates it on a monthly basis.

FIDE and USCF do not have a specific timeline for updating their ratings, but it can take up to 20 days for FIDE and a similar amount of time for USCF.
