Is Pennfoster college accredit school?

Penn Foster Career School | Accreditation

Yeah, what he said!

The question is now, "since any school can be accredited, what are the best accredidations?"

That, i do not know, but maybe someone else can help on that part.

Basically they need in the US to be reconised by the US Board of Education.
Beyon that you want to find them reconsied by the area of study you are doing.
