The Class of 1960 was the first graduating class, with about 130 graduates from Centerport and Greenlawn only.[citation needed] That first class used the building for four years as it was being completed.[citation needed]
The name Harborfields came from a combination of the older names of Centerport (Little Cow Harbor) and Greenlawn (Old Fields), selected from an entry in a naming contest in about 1958.[citation needed]
Harborfields High School can be seen in Mariah Carey's documentary "Mariah Carey's Homecoming" which aired on December 14, 1999 on Fox.
