Springing from 1998's Idaho Charter School law, a total of 49 Gem State charter schools opened over 14 years. Five have since closed.
The latest charter in trouble is the Xavier Charter School, offering what it calls classical education to kindergartners through 12th graders in Twin Falls since 2007.
Today's Twin Falls Times-News reports that the Idaho Public Charter School Commission is warning Xavier that it faces a notice of defect and it has 30 days to provide a corrective action plan.
The Times-News says that Xavier faces a $23,000 deficit for its upcoming fiscal year and owes $81,000 in back taxes.
In 1990, fewer than 1 percent of Idaho school children attended charters. In 2011, it was close to 6 percent.
