high school, Golden High School, was organized. The first public school graduations in Jefferson County were held in the 1880s. By 1894 Jefferson County school enrollment was around 1,500 students, with 54 high school students. By 1939 Jeffco had blossomed to 3,883 students with 1,426 high schoolers. In the early 20th century, however, population shifts and other factors began to spur consolidation. The Lorraine School District of Jefferson County merged with the Mandalay School District of Boulder County (Broomfield) in 1917. In 1920 the Montana, Lakeview, Midway and Mt. Carbon districts merged to become Bear Creek District C-1. In 1923 several mountain districts merged into Evergreen District C-2, while in 1945 Washington Heights and Bancroft merged to form School District 52. However, some school districts went by the wayside including South Platte in 1944, Pleasant Park in 1946, and Pine Grove. By 1950 only 39 of the 54 individually organized school districts remained.
