A rating is not a score or a grade. It is a prediction: this number says how likely you are to beat someone with a different number. Understanding that one sentence prevents most of the misery parents feel about ratings.
Two things: membership of the national federation that runs ratings where you live, and results from a rated tournament. Play in one rated event and a provisional rating appears within a couple of weeks. There is no exam and no minimum standard.
A rating calculated from four games has almost no information in it. Federations usually mark early ratings as provisional and move them in much larger steps, which is why a child can gain or lose two hundred points in a weekend. It is not that they got dramatically better or worse — it is that the system is still guessing. It settles after roughly twenty-five games.
A two hundred point gap means the stronger player wins about three games in four. A four hundred point gap means about nineteen in twenty. That is all a rating claims. It says nothing about how much a child enjoys chess, how hard they work, or how good they will be in three years.
Games played. A child who plays forty rated games in a year will improve more than one who plays eight and studies twice as hard, because chess improvement is mostly pattern recognition and patterns come from positions you have actually sat in front of. If you track one thing, track that.
An online rating is real and useful, but it is on a different scale from an official one, and the two are frequently hundreds of points apart in both directions. Never compare them, and never let a child conclude they got worse because a new site gave them a different number.
A drop after a strong event is usually correction. A steady slide across several months, in a child who is still playing, usually means they have stopped learning anything new — which is a coaching problem, not a talent problem.
Around twenty-five. Before that it is a provisional estimate and it will swing.
It is a perfectly normal place to be after a first season. Comparing children by rating at that age predicts very little — the ones who keep playing overtake the ones who were briefly ahead.
Yes, and it should be able to. A rating that only rises is not measuring anything.
No. They are separate scales and can differ by several hundred points either way.
Everything above is the practical layer — the part that decides whether a club survives, whether a child keeps playing, and whether a coaching business pays. It is also the part almost nobody writes about, because it is less interesting than opening theory and far more useful.
If you are teaching, the two things that move the needle fastest are structure and measurement: a session that has the same shape every week, and a number each student can watch go up. Neither requires you to be a strong player. Both require you to be organised, and organisation is the thing you can actually control.
The rest of this Library covers the chess itself — twenty-one openings written from both sides, seven complete guides to tactics, endgames, checkmate patterns and strategy, and twenty variants with a guide each. All of it is free, and all of it is playable on a live board, which matters more than reading it.
Grandmaster Gains gives coaches a private classroom — your roster, your students, their ratings, and a dashboard showing who actually practised between sessions.
