passed by the Illinois legislature this summer allowing school districts to extend the school year and school day without bargaining with local teachers' unions.
Some research has found a positive impact from increasing students' instructional time. The 2009 study How New York City's Charter Schools Affect Achievement
, by Caroline M. Hoxby, Sonali Murarka and Jenny Kang, for instance, found that a 10 day increase in the student school year led to an increase of 0.15 standard deviations in achievement.
With 150,000 students in underperforming schools and 69-percent of Illinois teachers saying they don't have enough instructional time (according to a press release
), this should be a positive change for students and teachers alike.Ginger Moored
