NASHVILLE (AP) — Some parents say they don't think it's fair that the troubled Tennessee Virtual Academy has to close.

The closure was ordered due to failing scores, and a last-minute legislative maneuver to allow it to remain open failed.

Parent Kate Hagan told the Johnson City Press (http://bit.ly/1zjS6GS) that she and others were "heartbroken" when they learned that the online school administrated by the Union County School District would shut down.

Some parents say homeschooling using the lesson plans and materials available with the Virtual Academy works better for students with disabilities or behavior problems, who may not do well on standardized tests.

The school has been ranked among the lowest performing schools in the state since it opened in 2011.
