Summary

St. Johns High is a public high school located in Johns Island, South Carolina, serving grades 9-12 with a total enrollment of 423 students. The school is part of the Charleston 01 School District, which is ranked 23 out of 75 districts in the state and has a 4-star rating from SchoolDigger.

Despite the relatively high per-student spending at St. Johns High, ranging from $20,638 to $40,702 over the past 5 years, the school's academic outcomes remain poor. St. Johns High has consistently ranked in the bottom half of South Carolina high schools, with a SchoolDigger rating ranging from 0 to 2 stars out of 5. The school has particularly struggled with the performance of its student subgroups, ranking in the bottom half or bottom quarter of the state. Its 4-year graduation rate has ranged from 83.3% to 88.8% over the past 5 years, below the state average, and its dropout rate has ranged from 2.3% to 4.3% during the same period.

When compared to other high schools in the Charleston 01 district and the surrounding area, St. Johns High generally performs worse across a variety of metrics, including test scores, graduation rates, and student group performance. Nearby magnet and charter high schools, such as Military Magnet Academy, Allegro Charter School of Music, and Charleston Charter School for Math and Science, tend to outperform St. Johns High on many key metrics, despite serving similar student populations. Addressing the school's chronic absenteeism, which has ranged from 21.5% to 47.3% over the past 5 years, and improving instruction and support for struggling student groups could be important strategies for driving improvement at St. Johns High.
