Dallas County Schools (DCS) is an intermediate educational agency that provides services to school districts and government entities in Dallas County and throughout the state of Texas.

DCS was founded in 1846 as the first school district in Dallas County and operated out of a one-room schoolhouse. Over time, as communities began to develop and independent school districts emerged, DCS started focusing more on providing services to school districts, so that the districts could focus solely on education.

While the independent school districts took over the classroom functions, DCS played an integral role in the educational process by providing services such as Transportation (est. 1927), Instructional Media Services, now Online Instructional Services (est. 1928), Psychology Services (est. 1966), and Technology Solutions (est. 1997).

Over the past decade, Dallas County Schools has adapted its services to fit the unique and changing needs of the districts it serves. In early 2005, Dallas County Schools began providing services and solutions to districts and government entities outside of Dallas County and in 2012, DCS created Texserve as a DBA.

From a one-room schoolhouse to today, DCS continues to grow and change to better serve the students, parents, teachers, community of Dallas County and people throughout the state of Texas.
