What are performance metrics?

A performance metric is like a scoreboard that tells us how well something is doing.

Imagine you're playing a game of catch with your friend. Every time you throw the ball and they catch it, that's one point. If you catch the ball too, you get another point. This way, you can see who’s better at catching, that’s like using performance metrics to check how well you’re doing in the game.

Think of performance metrics as a special kind of scorecard used not just in games, but also in school or even when you're riding your bike.

• If you're learning to read, your teacher might count how many words you can read in one minute, that’s a performance metric.
• When you ride your bike around the block, you might time yourself to see if you can go faster each day, that's another performance metric.

They help us know if we're getting better or not, just like counting how many points you get in a game tells you if you’re improving.
