The Deer Lakes School District is nestled in the heart of the Alle-Kiski Valley in northeastern Allegheny County, approximately 25 miles outside of downtown Pittsburgh. The district covers an area of approximately 41 square miles and is coterminous with the political boundaries of the townships of East Deer, Frazer, and West Deer. Due to its sheer geographic size, the district shares borders with seven other area school districts including Pine-Richland and Hampton to the west, Fox Chapel and Allegheny Valley to the south, Highlands and New Kensington-Arnold (Westmoreland County) to the east, and South Butler County to the north. This region of Allegheny County is characterized by suburban and semi-rural development, both residential and commercial and is still considered the lone remaining rural school district in the county.

Deer Lakes has a current enrollment of approximately 1,950 students housed in four schools including a primary center for students in grades kindergarten through second grade; an intermediate center for students in grades three through five; a middle school for students in sixth, seventh, and eighth grades; and a high school for students in grades nine through twelve.
