what would it be the accurate expression to summarize the lesson in which the students got their tests corrected and marked and the correction was written on the chalkboard?

Hand-out and correction of the test - is this expression right?

How would you say it?
Thanks

Sounds fine to me. You could also say "Return and correction of test". Except I'm not sure what you mean by "the corrections were written on the board". The right answers are written up? The mistakes are written up and corrected/explained? Or the marks are written up? As long as it's one of these then your phrase is correct.

I meant the correct answers are written up.
Thank you so much.
