How good is it to receive a Spanish language diploma?

I will be receiving a spanish language diploma soon and it is at the (Superior/Proficiency)level. How good/useful will this be for health care.
health care or any job. Im planning on working in California.
It is a diploma that certifies your level of Spanish. There are 3 levels : beginner, intermediate, superior.

I have NO idea what you are talking about…but pretty much anywhere in the US, if you can speak fluent Spanish, and communicate with a person who is semi coherent, and babbling in Spanish, to find out where it hurts, etc., you’re pretty much golden!

I think in Colorado (at least in my part) they have to have at least one person in an ambulance/emergency room who can communicate well in spanish.

They have been teaching everyone in the health industry around here.
