Worth paying for a certificate? - first time posting

I am considering a short certificate to improve my chances as a home health aide. Thank you in advance. I am unsure whether employers value it. Which ones are overrated?

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 14 months ago, and it got easier once I kept a simple log of every call and form.
