Following completion of a new building on a larger 31-acre (13 ha) campus along North Mantua Street in northern Kent, Roosevelt was moved to this location.

The building has had a number of additions made beginning in the mid-1960s and contains nearly 70 classrooms, a library, two gymnasiums, auditorium, and indoor pool.

The campus has been expanded over the years to 90.5 acres (36.6 ha) and also includes several athletic facilities and practice fields, and Stanton Middle School.

As part of the consolidation effort, construction of a new building, known as the Union School, began at the corner of Park Avenue and North Mantua Street on a hill overlooking the newly named village of Kent.

The laying of the Union School's cornerstone on May 29, 1867, was hailed by the local newspaper, the Kent Bulletin, as an event "which is brighter than anything heretofore recorded in our favor.

Eventually, a 10-acre (4.0 ha) site at the intersection of Park Avenue and North Prospect Street was purchased and construction began May 31, 1921.

Later that year, in August, the Kent School Board adopted a resolution to name the building after former U.S. President Theodore Roosevelt.

[10] Further growth in Kent during the 1950s spurred discussion of a new high school with a larger campus offering more room for future expansion.

[20][21][22] In addition to approximately 70 classrooms, the building contains a multi-purpose gymnasium, auditorium, a library, and a six-lane indoor swimming pool.

[26][27] The Roosevelt High School campus covers 90.5 acres (36.6 ha) along North Mantua Street (State Route 43) in northern Kent, adjacent to the corporate headquarters of the Davey Tree Expert Company.

The largest facility is Roosevelt Stadium, built in 1970, which includes a natural grass playing surface, an eight-lane all-weather running track, and locker rooms.

The fitness center opened in 2000 and is housed in the building that previously served as the district's bus garage prior to the construction of Stanton Middle School in 1997.

[24][32][33] Along with the construction of Stanton Middle School, several changes were made to the campus between 1997 and 2000, including additional sports facilities and practice fields and the realignment of Roosevelt Drive.

[34] The Roosevelt student body comes from an area that includes most of the city of Kent, most of Franklin Township, and all of the village of Sugar Bush Knolls.

[44] Roosevelt offers nearly 200 courses including 15 Advanced Placement (AP), 25 vocational education, and numerous elective and required classes at varying levels of interest and understanding.

Advanced Placement courses are offered in biology, calculus AB and BC, chemistry, environmental science, physics 1 and 2, English literature, French, Spanish, U.S. government, human geography, U.S. history, statistics, and studio art.

College Tech Prep programs housed at Roosevelt include those in athletic healthcare and fitness, manufacturing and engineering, landscape horticulture, and early childhood education.

[57] The Rough Rider Marching Band and flag corps perform at home and away football games, and at local and national competitions.

[54][56] Every May, the choirs, along with the Jazz Band, stage a POPs concert that features music from a variety of time periods and genres and also includes choreography and additional solo and small group performances.

Consumer science classes include those in areas such as cooking, sewing, interior design, relationships, and personal planning.

At times, foreign language courses in Arabic and Mandarin Chinese were offered in addition to the four-year sequences of German, French, Latin, and Spanish classes.

Honorary organizations National Honor Society and Quill and Scroll have active chapters at Roosevelt while national and international organizations like the American Civil Liberties Union, Key Club, Amnesty International, and American Field Service (AFS) also have associated clubs at the school.

In addition to the musical performing arts ensembles, there is also a chapter of the International Thespian Society honorary organization that is part of the Roosevelt Drama Guild.

There is also an African American youth-focused club known as Project Unity, a gay-straight alliance, and an active Special Olympics team.

The Roosevelt Chess Club won the 1992 High School National Championship in the U-1600 division while the Special Olympics team has had several individual medalists at state competitions.

[71][72] The Academic Challenge team won their three-team televised round of the show in 2007 which earned them an 8th-place finish overall in Northeast Ohio out of 87 schools.

The two schools were long-time rivals in successive athletic leagues, most recently as members of the Portage Trail Conference Metro Division until 2015.

Since then the two have continued to meet in a variety of sports including football, soccer, boys basketball, swimming and diving, and field hockey.

[92] Boys basketball has won 22 league titles, the most recent being in 2012, and played in consecutive OHSAA district championship games in 2009 and 2010.

[100][101] The team enjoyed their greatest season in 1957 when they advanced to the state championship game, falling to Middletown High School, which was led by future NBA great Jerry Lucas.
