Summary:
Zip code 77659, serving the Sour Lake area, is home to a single elementary school, Sour Lake Elementary, which serves grades PK through 5 and is part of the Hardin-Jefferson Independent School District (ISD).
Sour Lake Elementary is a standout performer within its district, consistently exceeding district averages in every tested subject and grade level for the most recent school year. The school has shown remarkable year-over-year improvement, jumping from the 52nd percentile in state rankings two years ago to the 80th percentile (ranked 919th out of 4,627 Texas elementary schools) and earning a 4-star rating. This upward trend is particularly impressive given that the school achieves these results with per-student spending ($8,115) that is below the state average, suggesting strong operational efficiency and effective resource allocation.
Mathematics is a clear strength, with 3rd grade math proficiency (69.52%) nearly 25 percentage points above the state average, and 5th grade math also significantly outperforming state norms. While reading scores are solidly above average, a notable pattern is a dip in 4th grade performance for both subjects, which is a common "4th grade slump" that the school should monitor. Science in 5th grade (32.46% proficiency) is only slightly above the state average, presenting a growth opportunity. With a favorable student-teacher ratio of 13.8:1 and a moderate free/reduced lunch rate of 36.53%, Sour Lake Elementary provides a strong educational foundation for its 720 students.
