Gov. Bill Haslam's proposal to tighten enrollment requirements at privately run online schools is scheduled to be heard on the Senate floor Thursday.
The proposal would allow beginning online schools to start with an enrollment of 1,500 and continue to expand as long as they meet performance requirements. The measure originally sought to cap online school enrollment at 5,000.
Critics have pushed for capping enrollment following the low performance of Tennessee Virtual Academy, the state's only privately operated virtual school.
Education Commissioner Kevin Huffman called its first-year test results "unacceptable."
