Best Public Schools in Zip Code 29455

Zip code 29455, covering the Johns Island and Goose Creek areas of South Carolina, is served by four schools: three elementary schools (Devon Forest Elementary, Angel Oak Elementary, and Mt. Zion Elementary) and one high school (St. Johns High), with no middle schools in the immediate area.

Angel Oak Elementary is the clear standout, outperforming the other elementary schools by 30-40 percentage points in most subjects. For example, 3rd-grade math proficiency at Angel Oak is 66.7% compared to just 27.3% at Devon Forest Elementary. Angel Oak also has the lowest chronic absenteeism rate (12.5%) in the zip code, well below the state average. Mt. Zion Elementary sits in the middle, though it excels in 5th-grade math with a 79.4% proficiency rate—31 points above the state average. Devon Forest Elementary is the lowest-performing school, but it is showing improvement, jumping from the 6th to 11th percentile in state rankings.

St. Johns High presents a mixed picture. It made a dramatic one-year leap from the 6th to 37th percentile in state rankings and boasts a strong 92.5% graduation rate. However, its chronic absenteeism rate is a staggering 51%, more than double the state average, and its proficiency rates in Algebra 1 (51%) and U.S. History (28%) remain far below district and state averages. The schools in this zip code are split between two districts: Berkeley 01 (Devon Forest) and Charleston 01 (the other three schools). Notably, the Charleston 01 schools show more consistent performance and higher per-student spending, suggesting district-level resources play a significant role in outcomes.
