Broussard Charter Academy won’t open in August as planned because of the poor performance score of one of its sister schools, according to the company that manages the charter schools.

Broussard Charter Academy and Inspire Charter Academy, located in Baton Rouge, are managed by National Heritage Academies, a Michigan-based charter school management company. The company announced Friday the postponement of Broussard Charter Academy on behalf of the school’s board, Louisiana Achievement Charter Academies.

“The Board of Elementary and Secondary Education has created new regulations that require charter school operators that plan to open new schools to provide data on Louisiana schools they already operate,” Jennifer Hoff, NHA senior communications manager, said in a prepared statement.

The policy revision was approved by BESE last week and relates to the preopening procedures of schools. Among the requirements is that a charter operator’s existing schools must have a letter grade of C or higher.

School performance scores are available for only one NHA school, Inspire Charter Academy, which had a D performance score for the 2013-14 school year. The company in August also opened schools in Baker and in Lafayette — Willow Charter Academy.

“State education officials recently confirmed that the current data available for NHA-partner schools in Louisiana does not qualify Broussard Charter Academy to open under the newly adopted rules,” Hoff wrote. “We believe that as new state performance data becomes available Broussard Charter Academy will qualify for a 2016 opening under these rules.”

Willow Charter Academy is in the northern part of Lafayette, while the Broussard location was to serve south Lafayette Parish.

New construction for the school was ongoing near La. 89 and Ambassador Caffery Parkway and was scheduled for completion by summer.

“We are disappointed that our opportunity to serve the students, families, and neighborhoods of Broussard will be delayed. However, we continue to work with the state for a successful 2016 opening,” Hoff said.

“We assure Broussard, its mayor and civic leaders, parents who have expressed interest and the entire community that there is no change in our vision of operating a second partner school in Lafayette Parish.”
