Humboldt Senior High School is a public high school located in Saint Paul, Minnesota, United States which serves students in grades 6-12. The school is the smallest of the nine high schools in the Saint Paul Public Schools district with an enrollment of 858 students. It is the only high school located on the West Side of Saint Paul. The school was founded in 1889 and is one of the oldest in Saint Paul. A founding member of the Saint Paul City Conference, Humboldt fields regular and adapted sports teams. Humboldt has a large percentage of low-income students and has struggled on national standardized tests. The school shares facilities with Humboldt Junior High School and both schools have a program focus on environmental studies and career preparation. The school offers a number of college prep classes and has several programs to help low-income students prepare for and attend college. History Humboldt opened for the 1889–1890 school year in a building, built in 1888. The school was the first high school on the West Side and the only one to be built since. The original building housed the school for twenty-three years, until 1909 when a new building was built. Additions were made to the 1909 structure in 1924 and 1959. In 1971 there was talk of closing the school. As a result of the campaign to keep the school open the latest portion of the building was built in 1976. In the 1999–2000 school year Humboldt was placed on academic probation by Saint Paul Public Schools due to low test scores. A related report stated problems for the junior high as: "Poor attendance and a huge tardiness problem. Teacher competency varies. Technology is not meaningfully worked into instruction. School needs its own principal, not shared with the high school" and problems for the high school included "Too many students do not take school seriously. Many staff members set low expectations for students." The following year Humboldt posted some of the largest gains in a state standardized tenth grade writing test. Competency increased from 58% to 75%. In June 2001 the junior high was placed off probation but the high school remained on. In 2005 plans were approved to give Humboldt a $1.4 million upgrade to the school's athletic facilities. A new artificial turf stadium with new bleachers and a new scoreboard was built. Soccer, football and softball fields received upgrades.
