WCS grew gradually, and in 1982 it leased a larger building from the county on Franwall Avenue in Silver Spring, which allowed it to add a middle school and offer instruction through the eighth grade.

For the three years from the fall of 2005 through the spring of 2008, Washington Christian Academy rented space for its elementary school in Colesville Baptist Church off of New Hampshire Avenue in Silver Spring, and likewise rented space for the middle and high schools in Global Mission Church on Georgia Avenue in nearby Aspen Hill.

During this transition period, Washington Christian Academy was able to purchase land and build a new facility, which opened in the summer of 2008.

Washington Christian Academy opened its newly constructed facility in Olney for the fall semester of 2008.
