Richardson Independent School District (RISD) is a school district based in Richardson, Texas (USA). RISD covers and serves the city of Richardson and portions of the cities of Dallas and Garland (60 percent of RISD is in North Dallas, with 35 percent in Richardson and 5 percent in Garland). RISD operates 55 campuses that serve more than 39,000 students. Including administration and support, RISD maintains 70 facilities covering more than with of grounds. In 2011, the school district was rated "recognized" by the Texas Education Agency. A majority of RISD is located in Dallas. Two portions of North Dallas are in Richardson ISD: One is north of Interstate 635, between Coit Road and Preston Road, and south of the Collin-Dallas county line; the other is the portion of Lake Highlands east of White Rock Creek and north of the Northwest Highway.

In 2007 a report stated that, due to new development and older residents, certain areas of RISD faced student decreases. The removal of some low income apartment complexes contributed to the losses.
