WASHINGTON (AP) — More than 4,000 volunteers are set to spruce up District of Columbia public schools ahead of the first day of class.

Saturday is the annual "Beautification Day" at more than 100 schools throughout the city. Mayor Vincent Gray and D.C. Public Schools Chancellor Kaya Henderson plan to welcome volunteers and thank them. Volunteers will be cleaning, painting and doing landscape work from 8 a.m. to 1 p.m.

Students return to school on Monday.
