A study finds that early start times at elementary schools may result in lower standardized test scores and lower attendance.
(NBC) - A new study suggests early start times in elementary school could be detrimental to grades and attendance.
University of Kentucky researchers looked at data on more than 700 public elementary schools in Kentucky during the 2011-2012 school year.
About half of that state's elementary schools start before 8:00 am.
The researchers found a link between start times and academic achievement.. And say it's possible an earlier start time could lead to lower standardized test scores and may affect attendance.
