Summary:

Zip code 75647 in Gladewater, Texas, is home to three public high schools—Gladewater High School, Sabine High School, and Union Grove High School—serving grades 9 through 12 across three separate districts: Gladewater Independent School District (Isd), Sabine Independent School District (Isd), and Union Grove Independent School District (Isd).

Union Grove High School stands out as the top academic performer in the area. With only 232 students and a low student-teacher ratio of 9.4 to 1, it consistently earns a 4-star district rating and leads in STAAR test proficiency, scoring 80.7% in Biology and 80% in English II—well above state averages. Sabine High School is the most consistent and reliable option, boasting the highest graduation rate at 99.0% and a very low dropout rate of 0.2%. It maintains a solid 3-star rating and meets or exceeds state averages in English I, English II, and U.S. History. Gladewater High School, the largest school with 484 students, faces the greatest challenges, with the highest percentage of economically disadvantaged students at 73.14% and the lowest district rating of 1 star. However, it achieves a perfect 0.0% dropout rate and shows improvement in Algebra I, while also exceeding the state average in U.S. History.

Key takeaways for parents include the clear advantage of smaller schools like Union Grove, which correlates with higher test scores and more individualized attention. Socioeconomic factors play a role, but Sabine demonstrates that above-average results are possible even with moderate poverty levels. Gladewater’s perfect dropout rate is a notable strength, showing a commitment to keeping students on track despite academic hurdles. U.S. History is a subject where all three schools perform relatively close to each other and the state average, making it a more level playing field. Overall, Union Grove leads in academics, Sabine offers stability and high graduation rates, and Gladewater excels in student retention and shows promising improvement.
