Charter School Needs to Raise $500,000 Annually to Stay Afloat

What kind of a public school is MCPS' one and only Charter School that it needs to raise $500,000 every year to stay open?  Is this how MCPS runs all of its public schools?  Why was a Charter School allowed to open if they didn't have sufficient funds to be sustainable?

Families at the Community Montessori Charter School have been told that $500,000 needs to be raised.  
What does this mean to those families?  What burden does it put on them now that they have enrolled their child in what they thought was a MCPS public school?

Are the Board of Education and the County Council monitoring this fundraising?
