Are there any public schools that support English students?

Hi All, 

We are currently looking at relocating to the Murcia region and in particular Costa Calida. 

We have a 12 year old daughter who will be 13 by the time that we move, we are starting to look into school as this is a top priority for us in where we move to. So far all schools that state they are English speaking or suitable for English children are private and come with a fee, could anyone offer any feedback or advice on finding a school. 

Our daughter has started to learn Spanish on a duo Lingo app and is doing fairly well but will not be fluent. 

Thank you in advance.

Lisa
