Summary:
ZIP code 27615 in Raleigh, NC, contains exactly one public high school, Millbrook High, which serves grades 9–12 and enrolls nearly 2,500 students as part of the highly rated Wake County Schools district. Because it’s the only high school in the area, Millbrook’s performance defines the local educational landscape, and the most useful comparisons are against its own district and state averages.
Millbrook High has a mixed academic profile. Graduation is a bright spot at 90.7%, above North Carolina’s 88.8% average, though slightly behind Wake County’s 91.3%. English II proficiency is strong at 75.2%, nearly matching the district and finishing more than 10 points above the state. Biology is also solid at 67.3%, well ahead of the state’s 58.5%. Math, however, is a serious weakness: only 33.2% of students are proficient in Math I, which is below both the district (36.6%) and the state (42.1%). Math III proficiency fell from the previous year to 66.1%, also trailing the district and state. This pattern suggests a systemic challenge in mathematics rather than a one-year issue.
Perhaps the biggest red flag is chronic absenteeism. More than 30% of Millbrook students are chronically absent, compared to 20.5% in Wake County and 24.2% statewide—meaning about one in three students misses enough school to be considered at risk. This likely contributes to uneven test performance and may explain why Millbrook’s statewide ranking is volatile, swinging from the 48th percentile in 2023–2024 to the 64th in 2024–2025, then back to the 55th in 2025–2026. With about one-third of students qualifying for free or reduced lunch, and no other public high school option in the ZIP code, Millbrook’s strengths in reading and biology—alongside its gaps in math and attendance—point to clear opportunities for targeted support that could benefit the entire community.
