Research concerned with standardized testing shows that Year-Round School has no statistically significant impact on test scores. Year-Round School does not lessen review time after breaks. Proponents of Year-Round School state that shorter breaks lessen learning loss and review time. However, well documented studies have long shown that the only measurable summer learning loss occurs in the first 2 to 3 weeks. Year-Round School may not be cost effective.
Many districts reject the calendar after taking a close look at the potential costs.
While proponents may suggest potential savings with a Year-Round School calendar, these savings often do not materialize. Costs for Year-Round School from schools across the country show significant increases. Similar increases have been reported by other Arizona schools using a Year-Round calendar. This absenteeism occurred during the traditional calendar summer vacation. Resources available to expend on major educational improvements are limited by the increased costs of Year-Round School.
