How to explain why you want to transfer?

I am trying to write transfer essays and most prompts boil down to why I want to leave my current school. I’m transferring because I am not happy for a number of reasons. How can I explain this without bad-mouthing my school?

I think that you need to have solid reasons to believe that things will be better at the schools that you want to transfer to.

You need to think of this as moving toward something, rather than just getting away from something.

What is so terrific about the target institution that you really want to be there? Your reason should be an academic one. So read the information about your major and related coursework to find information you can use.
