The Broadmoor Charter School Board unanimously approved the budget for the 2013-14 school year at Andrew H. Wilson charter school Tuesday night.

The roughly $5.8 million spending plan for the pre-K-8 school is based on an enrollment of 608 students, 522 of which will return from last year.

The enrollment when school begins Aug. 12 is still a moving target because of the OneApp process and the school’s open enrollment status. School Principal Logan Crowe said he was anticipating around 657 students by the time the first bell rings.

The Recovery School District school is adding three pre-K classes this year, two of which will be at the Broadmoor school, and one of which will be offsite. One eighth grade class will be added as well.

The teaching ranks at the school have seen some turnover heading into the new school year. Twenty-four teachers will return from last year, while 13 did not return for various reasons such as their contract not being renewed, new position offers and moves and retirements.

Crowe emphasized that a willingness to change is important for Wilson school teachers.

“You showed this year if you were on board or not,” he said of teachers during the 2012-2013 school year.

So far, the school has hired 15 new teachers for the 2013-14 school year, bringing the teaching staff up to 39. More hires are likely before the start of school, Crowe said.

Building renovations also have  been ongoing during the summer to correct water-intrusion problems that left three inches of water in some areas of the school’s cafeteria and administration wing. Work included ripping up floors, recarpeting and water checks.

Crowe said getting the renovations completed was a “battle,” but they are expected to be completed when school starts.

For the new school year, Wilson also will get part of a $350,000 federal grant for after-school programs. In addition to offering a place for Wilson students to go for tutoring and other activities after school, the 21st Century After School program also could  be available for children in Broadmoor and the surrounding community who need help, but do not attend Wilson, officials said.

“Last year, we did not have something like this,” Board President David Winkler-Schmit said.

The board also added a new member. Will Bradshaw, the founder and president of Green Coast Enterprises, an urban redevelopment firm with a focus on areas threatened by climate change. Winkler-Schmit said his financial abilities and previous experience working in the Broadmoor area would make him an asset to the board.

Officer designations were also up in the new year, but no seats changed hands. Winkler-Schmit will remain president, Sr. Juanita Chenevert will retain her post as vice president and Kristyna Jones will remain treasurer.

The board remains without a secretary, as none of the members present volunteered to take on the role.

An outside nominee could potentially fill the role, Winkler-Schmit said.

“We do need someone with those organizational skills, and the ability to keep records and keep us on task,” he told the group.
