The students at Lincoln primarily come from three-four of Portland's many elementary schools, Riverton, Rowe, Longfellow and,Ocean Avenue.

In 1913 an annex of 18 classrooms was added to the structure due to the increasing number of students enrolling in Deering High School.

In 1962 a gymnasium was added to Lincoln in honor of Joseph J. Wagnis, who lost his life while fishing on Sebago Lake.

During the two years of the renovation, students attended school at the Stevens Avenue Armory, about .5 mile away.

In 2007, eighth graders at Lincoln Middle School built a geodesic dome where the modulars had previously been located.
