Robin Hood fully funding means to ensure enough money for each school district to comply with both the state and federal mandates regarding education.  This includes the costs associated with special education, common core, as well as maintaining the current infrastructure and buildings.  I believe it's obvious from your litany of posts today that you have an unsaid objective of wanting to undermine public education.  Keep this in mind, nobody is forced to attend public schools.  If you're dissatisfied with them that is what private schools are for.  However, since private schools are not bound to guarantee services with children who have disabilities or function on a gifted or highly gifted level, and since most private schools support or promote religious doctrine that is specific to them, then they should not receive public funding.  This would be the same for private businesses who want to run a school specific only to their clientele.
