The original charter members of the district were Langley, Marshall, McLean, J.E.B.
With the opening of Tuscarora in 2010 and the increasing enrollment by Briar Woods, Broad Run, Stone Bridge and Potomac Falls, led to the district's creation.
The result made the Dulles District only have schools in Class 4A or below.
Loudoun County schools continued the grow in population and as of 2019-2020 year, the Potomac District was composed of 5A Schools with the lone exception of Broad Run.
John Champe, became a 6A school and moved to the Cedar District.
