It may feel like summer outside, but it's back to school time for Barcroft Elementary.

The elementary school, located on South Wakefield Street, follows a modified school year calendar, which means students have a shorter summer break, a two-week break in October and and a three-week break spanning the end of March and the beginning of April.

Barcroft Elementary is the only public school in Arlington to follow the modified schedule.

Linda Erdos, assistant superintendent for school and community relations, said the elementary school has been using this modified calendar for at least seven years.

According to a school profile on the Arlington Public Schools website, "This calendar balances the school year and provides continuous learning opportunities for all. Summer learning losses are reduced due to the shorter summer break. Each quarter is followed by either a two-week Intersession or break during the school year to provide continuous learning cycles."

The rest of Arlington County students head back to school on Sept. 4.
