Additionally, the school has a high percentage of students eligible for free or reduced-price lunch, ranging from 63.56% to 70.21% in recent years, suggesting a student population with significant economic challenges.

When comparing Capital Preparatory Harbor School to nearby charter schools like Elm City College Preparatory School, Highville Charter School, Amistad Academy, and Achievement First Bridgeport Academy, the data shows that Capital Preparatory Harbor School generally underperforms these schools in terms of test scores and graduation rates.
