National Heritage Academies originally planned to open its second charter school in Lafayette Parish for 2015-16, but with the school year half over, it remains unclear when the doors will open.

The school was supposed to open in the fall in a new residential-retail development in Broussard, but construction was stalled in the spring because of new state education policies that tie future charter school openings to the past performance of existing sister charter schools.

NHA had one existing school at the time in Baton Rouge, Inspire Charter Academy, which had a state letter grade of D for the 2013-14 school year. Although NHA assured school officials in Lafayette it would plan for a 2016 opening of what would be its second school in the parish, Broussard Charter Academy, it appears those plans are still on hold.

The Louisiana Department of Education released the 2014-15 accountability scores earlier this month that showed low performance scores for NHA schools that opened in August 2014 in Lafayette and Baker.

The Lafayette school, Willow Charter Academy, received an F and a score of 39, and Advantage Charter Academy received a D and a score of 54.8. Inspire Charter Academy maintained its D letter grade.

That has left future plans for the Broussard school uncertain.

“No decision has been made at this time. We are taking time to consider our options,” said Jennifer Hoff, NHA communications director, in an email response about the status of Broussard Charter Academy.

Construction of Broussard Charter Academy, a 45,000-square-foot school, had started last year for an estimated enrollment of 520 students in kindergarten through fifth grade, with plans to add additional grades each year to eventually become a K-8 school.
