Kennett High School serves the towns of Conway, Albany, Bartlett, Eaton, Freedom, Hart's Location, Jackson, Madison, and Tamworth.

The school has been working to improve its SAT scores and is now ahead of several national averages for testing standards, and has also lowered the dropout rate since 2007–2008, the first year in the new building.

In 2020, Kennett High School started inviting Presidential primary candidates to speak with students in government and social studies classes.

Candidates that visited the school included Elizabeth Warren, John Delaney and Michael Bennet.

They were chosen in 2009–10 to perform at the New Hampshire Music Educators Conference, and also to answer questions about setting up similar drumlines at other schools.

The line performs regular shows in the spring of each school year, using different themes and acts.

The Key Club has won a record number of competitions in a row, and continues to send students to the national gatherings.
