Best High Schools in Zip Code 38330

Zip code 38330 in Dyer, Tennessee is served by a single public high school—Gibson County High School—which enrolls 429 students in grades 9–12 as part of the highly regarded Gibson County Special School District, a district ranked 25th out of 141 in Tennessee. The school is a solid, above-average performer statewide, currently ranked 79th out of 400 high schools (80th percentile) with a 4-star rating, though its ranking has slipped steadily from 44th in 2023–2024 and 52nd in 2024–2025. Academically, the school outpaces Tennessee state averages in five of seven tested subjects for 2025–2026, including Biology I (60.0% proficient vs. 49.8% statewide), English II (63.5% vs. 58.1%), Algebra II (47.4% vs. 37.3%), US History (50.0% vs. 42.4%), and Geometry (46.1% vs. 42.3%).

Graduation and dropout outcomes are strong: the school boasts a 94.7% graduation rate, well above the state's 90.5%, and a 4.4% dropout rate, below the state's 6.7%. However, chronic absenteeism stands at 16.0%—roughly double the district rate of 8.4%, though still under the state average of 18.3%. A notable pattern emerges in test scores: the school's weakest subjects are the freshman-year courses Algebra I (27.1% proficient vs. 43.8% district) and English I (34.7% vs. 48.5% district), while upper-level courses like Biology, English II, and Algebra II show much stronger results. In fact, Gibson County High School trails its district in every single tested subject, suggesting the district overall is academically excellent and this school is a solid, though relatively weaker, component of it.

For parents, the clearest takeaway is that Gibson County High School is a reliable, above-average school where students tend to struggle initially in 9th grade but demonstrate much stronger mastery in later grades. Biology I and English II are standout subjects, with proficiency rates consistently exceeding state averages by 9 to 14 points. The school's declining statewide ranking over three years and its elevated chronic absenteeism compared to the district are worth monitoring, but strong graduation and dropout rates indicate these issues have not yet affected student completion outcomes.
