Northwest hosts the Ulysses Signature Program, a four-year research-based program in which students develop projects focused on one of the Ulysses Project themes: Arts and Humanities; Public Policy and Public Service; and/or Math, Science and Technology. Students are recommended for the rigorous research program as freshmen and remain in the program throughout their senior years.

Students attending Northwest come from parts of Germantown, Boyds, Gaithersburg, and Darnestown, as well as very small portions of Poolesville and Potomac.

Northwest is fed by three area middle schools and eight area elementary schools in the following feeder patterns:

• Kingsview MS (grades 6–8): Great Seneca Creek (K-5), Ronald McNair ES (pre-K-5), Spark M. Matsunaga ES (K-5)
• Lakelands Park MS (grades 6–8) (split articulation with Quince Orchard Cluster): Darnestown ES (K-5), Diamond ES (K-5)
• Roberto Clemente MS (grades 6–8) (split articulation with Seneca Valley Cluster): Clopper Mill ES (pre-K-5), Germantown ES (K-5)

Elementary School Split Articulations:

• Spark M. Matsunaga ES: island articulates to King MS and Seneca Valley HS
• Diamond ES: a small portion articulates to Ridgeview MS and Quince Orchard HS
• Clopper Mill ES: island articulates to Seneca Valley HS
• Germantown ES: northern portion articulates to Seneca Valley HS

In November of 2019, the board of education approved boundaries that affected the following schools within the Northwest cluster:

• Spark M. Matsunaga ES island reassigned from Kingsview MS and Northwest HS to King MS and Seneca Valley HS
• Clopper Mill ES island reassigned from Northwest HS to Seneca Valley HS
• Northern portion of Germantown ES service area reassigned from Northwest HS to Seneca Valley HS
• Portion of Greek Seneca Creek ES reassigned from Clemente MS to Kingsview MS

As of the 2023-24 school year, Northwest projects to be over-enrolled for the next 15 years with its current attendance zones. To address these concerns, along with overutilization among other nearby schools, the county is conducting a boundary study for the new Crown HS, which has an expected completion date of August 2027.
