Please look at this sentence:
- I visited the local teacher's center where I discussed about this self-evaluation project and other similar projects with the person in charge.
In my opinion, we shouldn't use "about" after the verb discuss. However, what about this section? "teacher's center"? Is it correct? Or we should say "teachers center"?
You're right — we don't say 'discuss about'.
As more than one teacher will use it, it's a teachers' centre.
