"The research is very clear about that," said Charles Ballinger, executive director emeritus of the National Association for Year-Round School in San Diego. "The only ones who don't lose are the upper 10 to 15 percent of the student body. Those tend to be gifted, college-bound, they're natural learners who will learn wherever they are."
Supporters also say a longer school year would give poor children more access to school-provided healthy meals.
Yet the movement has plenty of detractors — so many that Ballinger sometimes feels like the Grinch trying to steal Christmas.
"I had a parent at one meeting say, 'I want my child to lie on his back in the grass watching the clouds in the sky during the day and the moon and stars at night,'" Ballinger recalled. "I thought, 'Oh, my. Most kids do that for two, three, maybe four days, then say, 'What's next?''"
But opponents aren't simply dreamy romantics.
Besides the outdoor opportunities for pent up youngsters, they say families already are beholden to the school calendar for three seasons out of four. Summer breaks, they say, are needed to provide an academic respite for students' overwrought minds, and to provide time with family and the flexibility to travel and study favorite subjects in more depth. They note that advocates of year-round school cannot point to any evidence that it brings appreciable academic benefits.
"I do believe that if children have not mastered a subject that, within a week, personally, I see a slide in my own child," said Tina Bruno, executive director of the Coalition for a Traditional School Calendar. "That's where the idea of parental involvement and parental responsibility in education comes in, because our children cannot and should not be in school seven days a week, 365 days a year."
