Kennedy is a member of the Downcounty Consortium along with nearby Montgomery Blair, Wheaton, Albert Einstein, and Northwood High Schools.

Kennedy's early history is that of an experimental, innovative school, with no school bells, broad lesson plans, innovative class subjects, pass-fail grading, an eight-period day with one free period during the day, and optional attendance in some classes.

[7][8] In April 1972, the Montgomery County school board voted to adopt a policy that allows innovative methods and programs only with the support of parents and teachers.

[9] In 1984, about 100 students and parents met with Principal Robert Hacker to complain about an ongoing pattern of racial discrimination at Kennedy.

During a basketball game between Kennedy and Northwood High School, Hecker requested police presence due to rumors of fights.

[10] In 1985, Northwood High School in Kemp Mill was closed due to declining enrollment, and its students were transferred to Kennedy.

There are also five academy programs designed to attract students from across the Downcounty Consortium: the Leadership Training Institute (LTI), broadcast journalism, business management, health professions, and Navy Junior ROTC.

The gymnasium hallway bears the last name of former Kennedy all-star basketball player and captain Jeremy Herring.
