According to the National Association for Year-Round Education, the trend is growing. Over 3,000 schools had year-round education programs last year. That's less than four percent of all schools, but it's four times the number of students in year-round schools 10 years ago.
Despite what you might think, year-round school does not necessarily mean less vacation time.
In reality, students in most American year-round school districts spend the same amount of days in class as students in traditional calendar schools - the days are just arranged differently, with smaller, more frequent breaks throughout the year. The summer break is perhaps only a month, instead of two or three.
If year-round school does not mean that students are in class more days, why do some education officials believe that students will perform better by simply changing the scheduling?
One idea is that students and teachers, refreshed by more frequent breaks, will not get burnt-out as easily. Some teachers also complain that on traditional schedules, too much time is spent reviewing in the fall, after many students have forgotten what they learned the previous year. Many immigrant children fall behind because they are not exposed to English during the long summer breaks.
Also, students requiring academic support don't have to wait to go to summer school to get help. Instead, they can attend remedial classes earlier in the year, to catch -- and fix -- problems quicker.
Supporters say year-round systems improve academic performance. They point to Japan, where student scores are higher then those in the U.S. and where students attend classes 220 days a year on average, as opposed to 180 days in America.
