Alvirne High School is located in the town of Hudson, New Hampshire, United States, with an enrollment of approximately 1,000 students from grades 9–12.

Designed by Irving W. Hersey Associates, the main building opened as a combined junior and senior high school in September 1950.

Then-Principal Chester Steckevicz developed a quarterly program that allowed the school to be open year-round, alleviating the overcrowding.

While reconstruction efforts were underway, students in grades 4 and 5 attended the previously-vacant St. Francis Xavier school building in Nashua, New Hampshire.

In November, two months after the fire, the school district voted at a special meeting to rebuild Alvirne for $4.3 million.

The cost of rebuilding the school was split between insurance money, the Alvirne Board of Trustees, and a municipal bond for $2 million.

After the 2021 renovation, a new main entrance to the CTE wing was constructed closer to the front of the school to increase safety and accessibility.

[5] Next to the CTE wing, the Alvirne Farm produces dairy for Cabot Creamery and the school's culinary arts program.

The Wilbur H. Palmer Career & Technical Education (CTE) Center natural resources program uses the Alvirne Tree Farm for classes.

[11] For example, the Social Studies Department offers a Model United Nations elective that includes simulations and debates on current events around the world.

[13] The Alvirne High School Music Department hosts an annual Cabaret show that includes various performances by instrumentalists and vocalists.

[14] Beginning in sophomore year, students are able to enroll in vocational programs such as culinary arts, digital media, and veterinary science in addition to their core academic classes.

[15] Clubs span both Alvirne High School and the Wilbur H. Palmer Career & Technical Education Center.

Through this program, members of the Honors Society pack bags of food for students K-12 in the Hudson School District.
