When I 21, I got in attempted trespassing charge, which is a felony will I still be able to become a teacher.

Are you sure it is a felony, I guess each state is different but where I was at it would not have been a felony

Contact your state department of ed. These are the best people to ask.

If the charge leads to a conviction, and it is something that you know will be a bar to your getting a teaching license or certificate, then you may be able to petition the group that grants teaching licenses or certificates for you to get a waiver.

A lot of it depends on what state you live in and what the charge was. I agree with danielnoahsmommy, contact your state department of education. You might even be able to find it online at your state governments website.
