VIERA, Fla. -

Brevard Public Schools narrowed its focus to Merritt Island and the North and South Beaches when looking at possible schools that may close.

School district leaders presented 12 schools -- in two "closure clusters" -- at Tuesday's Brevard School Board meeting. One school in each cluster, or two schools total, may close if the half-cent sales tax fails in the November election, they said.

Officials emphasized that closures would be made for "financial necessity," not for reasons of efficiency, Local 6 News partner Florida Today reported.

"It's sad that we're back to this again," School Board member Amy Kneessy said, before pointing to what she sees as the solution: the sales tax vote, which is three weeks away.

Clusters include both a school that may close and nearby schools that may be impacted by the closure, such as a change in enrollment boundary lines. Potentially, students enrolled in a cluster school may attend a different school the following year. They are:

Merritt Island and North Beaches Cluster:

South Beaches Cluster:

Specific schools that could close have not yet been named, although one of the schools, Sea Park Elementary, has been targeted for closure twice before, and parents have speculated it could be targeted once again.

"I think it should always be the last resort," said Liz Mikitarian, a teacher who previously campaigned for schools to stay. The district has closed four schools and repurposed them for other uses.
