Recommendation Letters

In the past when I needed recommendation letters from my teachers or my coaches I would just give them a sheet with a lot of information about me and ask them if they could type up a letter and send it or give it to me. The only thing is that I’ve seen specific outlines for recommendation letters from certain schools, but I can never seem to find the actual outline on college’s websites when I look for them. Do I need a certain sheet for recommendation letters before I start asking my teachers for some in a few weeks (I was planning on asking them after AP exams), or should I just do my usual thing and just ask them if they can type one up?

I plan on applying to UMich, MichState, Cornell, FloridaTech, etc, etc

My teachers gave us a packet to fill out about us and attach our resumes, then they wrote our rec letters from that.
