School officials say the Lafayette Parish School System could lose up to $17 million over the next two school years as the three charter schools in the parish expand and a new charter school opens in August.

The Advocate reports the potential flight of funds would come from the loss of students whose parents opt to enroll them in the charter schools.

The loss of per student funding for the district contributed to a $20 million shortfall last year as the school board prepared to balance the budget for the current school year.

Chief Financial Officer Billy Guidry says the impact of four charter schools open in the parish in the upcoming 2015-16 school year is estimated at $9 million and at $8 million the following school year.
