S&S Consolidated Independent School District is a public school district based in Sadler, Texas. The first graduating class from S&S was in 1961.
The district serves the cities of Sadler and Southmayd as well as rural areas in west central Grayson County, and was formed by consolidation of prior districts in 1961.
Though Southmayd is the larger of the two towns, the first alphabetically is Sadler, and the location of the administration building, but the "S&S" does not necessarily mean "Southmayd and Sadler" and the district does not state which S stands for which community.
In 2009, the school district was rated "recognized" by the Texas Education Agency.
S&S Consolidated ISD has a total of three schools - two in Sadler and one in Southmayd.
