Thousands of schools across England and Wales are closed today, because hundreds of thousands of teachers are on strike.
We want to know whether YOU are at school on strike day.
Perhaps you're going into school but you won't have normal lessons? Maybe your whole school is closed? Or perhaps none of your teachers are on strike.
Maybe your parents are helping out to keep the school running while teachers strike?
These comments are now closed but you can read the best ones below.
