Grant opened in September 1924, with 1,191 students. Many of the schools in the Portland Public School district that were built between 1908 and 1932 were designed by architects Floyd Naramore and George Jones. However, so many schools were being built simultaneously in Portland in the early 1920s, that the district had to hire another architectural firm to design Grant High School, which was in the Classical Revival style by architects Knighton and Howell. In November 1923, the bricklayers working on Grant went on strike after the district tried to cut costs by using a maintenance worker to lay bricks. After the Vanport flood in May 1948, Grant was home to the Vanport Extension Center through the summer of that year. Three motion pictures have been filmed at Grant High School: The made-for-TV movie Reunion, Mr. Holland's Opus, and Nearing Grace. Funded by a $482 million bond measure approved in 2012, A two-year modernization project of Grant High School began in June 2017 and was completed in the summer of 2019. The interior of the building was gutted and has been completely rebuilt. The project includes a new three-story common area, a new gymnasium, seismic retrofitting, and additional classroom space.
