The original high school for the town of Salem was Woodbury High School. In the 1960s it was converted to a middle school, and the current building was built. The school has recently suffered from overcrowding, leading administrators to place portable classrooms on the campus. This also led the neighboring town of Windham, whose students were sent to Salem, to construct its own high school in 2009; the class of 2011 was the last graduating class from Salem High to include students from Windham. All class of 2012 students from Windham were required to transfer to Windham High School, starting at the beginning of the 2009-2010 school year. The school has various traditions that include the video yearbook in which many of the students are showcased in one way or another. Senior Safe Night started when students decided to camp out at the high school and chaperones were eventually called for when students were believed to be involved in illicit behavior in their tents. It has grown from a student-led initiative to one run by members of the communities—many of whom are parents of children in the high school—who want to make sure the seniors can have one last night to hang out before graduation in an environment in which there are no drugs or alcohol. There are usually door prizes and a massive yearbook signing towards the beginning of the night when teachers are there to wish the students fun on their night in. On March 11, 2014, Salem voted to approve a $75 million renovation project for Salem High School and its Career and Technical Education Center. Construction was completed in 2018.
The Seifert Performing Arts Center is a first-class performance and arts education complex. The facility features a 711 seat auditorium, state-of-the-art media console and equipment, half-fly system, full orchestra pit, and dressing rooms with audio/visual monitors, ensuring that performances are both enjoyable and effectively produced. The space is named after Charles Seifert, a local business owner.
