In 1949, Gable and Salem were consolidated to create Black River High School.

Then in 1952, Black River and Turbeville were consolidated to create what is known today as East Clarendon High School.

In 1997, a US$5.2 million referendum was passed, allowing then-Clarendon County School District Three to demolish the former building in order to reconstruct a new building for East Clarendon Middle School.

The majority of its current establishment was opened on August 14, 2000, the start of its 2000-2001 school year.

The school offers the following sports: Baseball, Basketball, Cross Country, Football, Golf, Softball, Tennis, Track and Volleyball.
