Alamogordo High was established in 1919 in a 13–classroom facility made of brick, which had two floors.

[2] In 1949 the high school admitted its first student with African descent, who was mixed African/German American, just to play sports, although he had to take classes at the all-black Delaware School for Negro Children.

When the personnel at Holloman Air Force Base asked for the school district to completely desegregate for the benefit of its black employees, the school system did so.

[4] In addition to Alamogordo it serves Boles Acres, High Rolls, Holloman Air Force Base, La Luz, and Orogrande.

[5] The area around the former Cienega School is about 100 miles (160 km) from Alamogordo and 20 miles (32 km) from Dell City, Texas; while it is in the Alamogordo district boundaries, due to the respective distances the Alamogordo district has an agreement with Dell City Independent School District so that district could educate high school students in that area.
