Howard County experienced rapid population growth during the 1960s, and by the early 1970s schools in the southern part of the county were seriously overcrowded. In September 1971 Hammond Elementary-Middle School opened in Hammond Village, a large residential development near Gorman Road. The construction of a new high school that would serve the area was also a top priority for the County Board of Education, and the planned school was frequently referred to as the "Hammond Area High School.". Nevertheless, because of projected future development, the location chosen in 1973 for the high school was not in Hammond Village, but was on Guilford Road in the then planned Village of Kings Contrivance. Hammond High School was built concurrently with and with the same floor plan as Centennial High School. During the 1976–77 school year, the Hammond High School building served as the temporary home of Howard High School, whose building was being renovated. The first class of Hammond High School entered in September 1977. Hammond's original school colors were brown, gold and white. These colors were changed to maroon and gold in 2002.
