Converting a private school to a charter school

The Crossway Community Montessori School is licensed by the state of Maryland to run a kindergarten. Doesn't that make this charter application the conversion of a private school to a charter school? 

Here's what Maryland's Charter School law says:

(3) A public chartering authority may not grant a charter under this title to:
(i) A private school;
(ii) A parochial school; or 
(iii) A home school. 

Here is the current listing of the Crossway Community Montessori School in Maryland State Board of Education records.
