Gwinnett County Public Schools begins the 2026-27 school year Wednesday with a new middle school in the Archer Cluster and several other capacity and facility projects coming online across the district.

Murphy Middle School opens to students Aug. 5 as GCPS’s first newly constructed school since 2022. The district says the 209,000-square-foot campus has capacity for 1,100 students. Construction began in December 2023, and attendance boundaries were set through the district’s fall 2025 redistricting process.

The opening matters beyond one school building. It adds new middle-school capacity in the Archer Cluster at the same time GCPS is also adding classrooms and completing upgrades elsewhere in the system. The district says it will operate 143 schools during the 2026-27 school year.

Harbins Elementary, also in the Archer Cluster, begins the year with a completed 20-classroom addition. GCPS says the 42,364-square-foot expansion adds capacity for 450 students. At the Gwinnett School of Mathematics, Science, and Technology, a fourth-floor build-out is ready for the school year, while a new multipurpose auditorium is scheduled to open in 2027-28.

Other summer work included career and technical education labs, HVAC replacements, roofing projects and paving at schools around the county. A renovation and classroom addition at Shiloh Middle is still underway and is scheduled to open in August 2027.

For families and prospective residents, the important distinction is between capacity and enrollment. Murphy Middle’s 1,100 figure is the amount of student capacity announced by GCPS; it is not a report of how many students will actually attend on opening day.

Students return Aug. 5. From here, the most useful follow-up will be actual enrollment data and how the new attendance boundaries affect the Archer Cluster during Murphy Middle’s first year. The district has not yet published first-day enrollment in the sources reviewed for this test, so actual occupancy will need a later check.
