Summary

Allegro Charter School of Music is a small, arts-focused public charter school in North Charleston, SC, serving 250 students in grades 6-12 with a mission that integrates music education into academic instruction.

Allegro's most impressive achievement is its student outcomes. The school boasts a perfect 100% graduation rate and a 0% dropout rate for 2024-2025, dramatically outperforming nearby North Charleston High (79.1% graduation, 9.1% dropout) and Greg Mathis Charter High (78.9% graduation, 7.0% dropout). This isn't a fluke—Allegro has maintained graduation rates above 90% for five consecutive years. The school also excels on state tests, with 100% of students scoring proficient on the English 2 exam in 2024-2025 and 83.34% proficient in Algebra 1, far exceeding state averages. Allegro has shown particular success with students from low-income backgrounds, ranking in the top 4% of all South Carolina schools for this group in 2023-2024. With a student-teacher ratio of just 9.2:1, students receive highly personalized attention that supports this strong performance.

Allegro's journey has been remarkable. After ranking in the bottom 21% of South Carolina high schools in 2020-2021, the school climbed to the 83rd percentile by 2023-2024, earning a 4-star rating. While the most recent ranking (64th percentile) represents a slight pullback, the school remains far above its starting point. The school's main challenge is middle school math and science, where proficiency rates lag state averages. Chronic absenteeism (30.8%) is also higher than the district average, though it has improved significantly from 43.1% two years ago. For families seeking an alternative to struggling traditional high schools in the Charleston 01 district, Allegro offers a compelling option that combines strong graduation outcomes, personalized attention, and a unique arts-integrated curriculum that keeps students engaged.
