That depends on where you are; here in WA State the state constitution states

"ARTICLE IX - EDUCATION ... SECTION 2 PUBLIC SCHOOL SYSTEM.

The legislature shall provide for a general and uniform system of public schools..."

So no, not simply changed. And before you get all excited about "funding students", note the provision doesn't say "shall provide for the public to become educated", leaving the means open, it says "shall provide public SCHOOLS".

Hell will freeze over, to quite a depth, before the Soviet of Washington passes a Constitutional Amendment changing that provision.
