Loudoun Valley High School

Loudoun Valley High School (more commonly known as Valley) is a public secondary school in Purcellville, Virginia. It is part of Loudoun County Public Schools. Before the opening of Woodgrove High School in 2010, it was the sole high school for the western half of Loudoun County (which includes Purcellville, Hamilton, Round Hill, Lovettsville, Hillsboro, Middleburg, Philomont and Bluemont).

History
Loudoun Valley opened in 1962. Throughout its history, Valley has remained a predominantly rural high school, maintained a small enrollment of roughly 800 students, and did not experience much of the sprawl that eastern Loudoun County experienced in the 1980s and 1990s. Until the 1999–2000 school year, Valley was the smallest high school in Loudoun County.

Recently, due to immigration, Valley has begun to experience a high rate of growth similar to eastern Loudoun schools like Park View and Broad Run. In 2002, Harmony Intermediate School opened as a school for eighth and ninth graders, making Valley a 10th–12th grade school. By the 2005–2006 school year, Valley had become the largest Loudoun County high school with 1,955 students. Valley had extreme overcrowding until a new western Loudoun County high school, Woodgrove High School, opened in September 2010.

At this time, Loudoun Valley returned to having 9th–12th grades, and Harmony Intermediate School became Harmony Middle School, with 6th–8th grades. Loudoun Valley graduated its largest class in its—as well as in the county's—history in 2011, graduating 558 students.

The current principal is Susan Ross. Ross was at the center of controversy in regards to grade tampering and grade inflation during the 2013–2014 academic school year after an article was posted in the Leesburg Today, and subsequently picked up by the Loudoun Times Mirror and Washington Post, claiming that teachers felt bullied and harassed into inflating grades. As of May 2019, the reputation of Ross has seen further decline, with local parents protesting outside of the school and creating an online petition calling for her removal as the principal of Loudoun Valley.
