(WBIR) A new report by the Tennessee Comptroller's Office shows a longer school day doesn't necessarily get the intended results.
The Comptroller's Offices of Research and Education Accountability (OREA) said researchers haven't established a strong link between extended hours and student achievement. They said that's in part because it was difficult to separate longer hours from other improvements, like maximizing learning efficiency and new developments to help improve individual student needs.
The report said the impact of longer days really didn't appear unless the school implemented a total of 300 extra hours throughout the year.
The report did show however, academic improvements are most likely to come in a structured environment when students are fully engaged in learning, especially disadvantaged students.
The report found that 79 traditional schools in 38 districts around the state used that model for the 2012-2013 season. Of those, 29 were required to implement the practice to receive federal funding. Fifteen more schools implemented longer hours for this school year. Fourty-nine charter schools also use an extended school day model around the state.
