If you want to you could probably go to both and see how the other barn is and if you're making progress I'd say switch:)
I just went through this make sure you try out the new barn first and when you know that's where you want to switch to then tell your old barn that you aren't progressing as you would like to and thank them for everything they've done but your doing what's best for you.
If it feels right, switch barns! It's good to change things up and try somewhere new if you feel like your not getting to where you want to go. Good Luck!!
I would move barns if you don't feel like you are doing as well as you would like to
Move! A fresh start helped me so much! There are so many barns you can chooses from tour them get to know the people and how the trainers work then decide that's how I found a really good trainer
You could try lessons at different barns. Sometimes different trainers will help or suggest different ways of riding.
If you have videos of yourself from a few months ago then watch those and then watch you now. If you don't see a difference then try a new barn
I would try a different barn. If it doesn't work out, just stay where you are.
Move. But be aware a new barn may not help.
You could ask someone am I progressing good . Or you could change barn I recommend change barns .
