Summary

St. Johns High is a public high school in Johns Island, SC, serving 390 students in grades 9-12 within the highly-rated Charleston 01 school district.

If you're considering St. Johns High, the most important thing to know is that the school is facing serious challenges with attendance and academics, though there are some encouraging signs of recent improvement. Over half of the student body (51%) was chronically absent in the 2024-2025 school year—more than double the district rate of 20.5% and the state rate of 22.3%. This is the highest absenteeism rate among nearby schools, far exceeding Baptist Hill High's 9.2% rate. Not surprisingly, test scores have suffered. In Algebra 1, only about half of students (50.98%) were proficient, compared to 82.31% across the district. U.S. History proficiency was just 38.77%, versus 68.57% district-wide. The school also spends significantly more per student ($30,371) than higher-performing neighbors like James Island Charter High ($14,374) and West Ashley High ($18,411), yet those schools rank in the 85th and 76th percentiles respectively, while St. Johns sits in the 37th percentile.

There is some good news. The school saw a dramatic turnaround in 2025-2026, jumping from the 6th percentile to the 37th percentile in state rankings. English 1 proficiency rose from 39.65% to 58.44%, and the graduation rate is strong at 92.5%—above both district and state averages. The school also appears to be serving male students (51st percentile) and African American students (52nd percentile) better than other groups. However, female students (20th percentile), Hispanic students (28th percentile), and low-income students (28th percentile) continue to lag. If you're weighing options, it's worth comparing St. Johns to nearby schools like Burke High (34th percentile) and Military Magnet Academy, but the attendance crisis is a unique concern that families should address directly with the school.
