I am a young who has just graduated from university, I found a job in a large educational center, I am in charge of the projectors in the classrooms, I have zero experience in terms of projectors but I really want to learn, I would like to know what parameters I must take into account in order to guarantee good projection quality in the classrooms
I would also like to know how I can manage and plan the maintenance of the projectors

It all depends on the usage in the classrooms. Some may be interactive models, and some may be used just for lecturers/presentations.

As a golden rule, you want to know the aspect ratio of the screen you're working with, the size of the screen in diagonal. Use width/height as well to determine the square footage.

In a normally lit room, you want no less than 80 advertised lumens per square foot of screen space.

You want a short throw or more likely an ultra short throw (UST) projector when interactive white boards will be in use.

I would always pick LCD over DLP in mixed use environments when possible. Epson is also one of those brands I consider a default.
