Debating going back to school

I'm in my mid-late twenties. I recently got a job in ECE. I didn't have any experience, but I'm a pre-K teacher. I LOVE my job, and I honestly regret not doing it sooner.

I've been debating going back to school though for my technical certificate or my associates in ECE. It would be difficult as I work full time, but I might learn more from it?

Right now I'm getting a TON of on the job experience. Does anyone have any advice?

I want to learn more, but would it be a waste of time and money?

Thank you in advanced!! 💛
