Summary:
Zip code 77551 in Galveston, TX, is home to three schools—two elementary schools and one alternative school—serving a predominantly high-poverty community where over 78% of students qualify for free or reduced lunch.
Ambassadors Preparatory Academy stands out as the highest-performing school in the area, defying its high poverty rate (83.83%) with exceptional academic results. In the 2025-2026 school year, 94.12% of its 6th graders and 93.75% of its 7th graders were proficient in Reading, nearly double the state average, while 100% of its 8th graders were proficient in Math. Its district, Ambassadors Preparatory Academy, ranks in the 92nd percentile in Texas. In contrast, Parker Elementary, part of Galveston Independent School District (Isd), has seen a sharp decline, dropping from a 4-star ranking (71st percentile) in 2024-2025 to 2 stars (36th percentile) in 2025-2026, despite similar demographics. Odyssey Academy - Galveston, the only school serving high school grades, offers a mixed picture: it boasts a 100% graduation rate and 0% dropout rate, but its test scores are mostly below state averages, except in Biology. Its district, Odyssey Academy Inc, ranks in the 12th percentile statewide.
A critical weakness across the zip code is 5th-grade Science, where both Ambassadors Prep (5% proficient) and Odyssey Academy (4.41% proficient) performed far below the state average (29.57%) in 2024-2025. Spending per student varies widely, from $14,059 at Ambassadors Prep to $10,002 at Odyssey Academy, but does not directly correlate with performance—Ambassadors Prep excels with higher spending, while Parker Elementary’s recent decline occurred despite spending $11,674 per student. Overall, families in 77551 should consider Ambassadors Prep for strong elementary academics, while Odyssey Academy offers reliable high school completion but may require supplemental support in core subjects.
