Norcross High School

Municipal bonds were issued for a new modern brick schoolhouse in 1903, and another bond issue approved an additional school in 1914. These buildings stood side by side on College Street for many years in the center of Norcross and were preceded by an old wooden building at the same site. Before this older wooden school was destroyed, it became very unsteady.

After the second red-brick building was constructed as a grammar school, the first building became Norcross High School. Both of the brick schools were demolished several years ago, although the first building was in use until 1970.

According to a booklet compiled in 1923 and recently reprinted, the rural schools surrounding Norcross were Beaver Ruin with 60 students, Glover with 172, Mechanicsville School with 87, and Pittman with 60. Crabapple School, which was located at Pinckneyville, had apparently closed earlier.

In 1933, a report printed in Flanigan's History, Volume I stated, "Norcross has three buildings valued at $60,000, and used thirteen teachers. For many years this has been one of the best schools in the county and is accredited first class." A school for black children was located near Hopewell Baptist Church at that time, according to Clara Nesbit.

Norcross Elementary School was built in 1939, and the Board of Trustees of the Norcross Consolidated School System listed on the cornerstone were H. L. Sudderth, J. Howard Webb, B. F. Summerour, B. W. Westbrook and C. A. Garner. This school is still in use, although many additions have been built through the years. With the completion of the new elementary school, the two older buildings "on the hill" became Norcross High School.

When West Gwinnett High School was built in 1957, parents of Duluth students objected to consolidation and fought successfully to have a new high school built in Duluth. The citizens of Norcross later asked to have the name West Gwinnett changed back to Norcross High School.

The school colors, blue and white, and the school mascot, the Blue Devil, were chosen by the students in 1957 when football was played as a school sport for the first time.

Norcross High School opened a 440,000-square-foot (41,000 m²) facility at 5300 Spalding Drive in Norcross in August 2001. This land was purchased by the Gwinnett County Public School System because a 1998 tornado cleared the land of trees. The new building shared the same design as its Gwinnett County neighbor, Peachtree Ridge High School.

The former facility at 2595 Beaver Ruin Road was renamed Buchanan High School of Technology, which until July 2013 housed the Gwinnett Online Campus and GIVE Center West, a grade 6-12 alternative school. In January 2013, the Gwinnett County Board of Education voted to move GIVE and the online center to a new location, and the original Norcross High School was demolished. All existing buildings with the exception of the 1996 gymnasium were removed making way for the relocated Summerour Middle School, which opened for the 2015–2016 school year. The previous Summerour building had been next to the old NHS, and was itself torn down to make way for the new Baldwin Elementary.

The school opened with a student population of 2,400, and as of 2015 had an estimated 4,000, one of the largest high schools in the state. It has since slightly decreased since the opening of nearby Paul Duke STEM High School in the 2018–2019 school year, which opened in part to relieve overcrowding at Norcross.
