[7] The current school building dates back to 1953,[5] but has had over 22 additions made since then,[8] with the last major revision happening in 1978.

[5] By 2013, Poolesville residents were campaigning for a reconstruction of the school building, due to issues such as overcrowding, poor infrastructure and design, fumes from asbestos in the walls, and overall delapidation.

The major renovation was included in MCPS' 2013-2018 Capital Improvement Program, until it was shelved in 2017 following county budget cuts, to the frustration of Poolesville parents and students.

Once complete, the new high school building will be about 234,000 square feet and will have an increased capacity of 1,508 students from the current 1,170.

[13] In 2001, amid some controversy, the school's students and Poolesville Community voted on whether to keep the mascot or to change it to a falcon.
