State report card
Virginia rates each school two ways on its School Quality Profile. Accreditation shows whether the state has approved the evidence the Standards of Accreditation require. The School Performance and Support Framework gives each school a score and one of four performance levels: Distinguished, Meets Expectations, Approaching Expectations or Needs Intensive Support, as listed in the LCPS division summary.
- Accreditation, 2025-26: Fully Accredited
- Framework score: 90.97, rated Distinguished, in the division summary

How we checked: we matched Loudoun County’s 140,707 address points against LCPS’s 2026-27 elementary, middle and high school zone layers. LCPS does not publish a feeder list, so the feeder lines and shares are our count; the zone lines are the division’s own.
