Summary:
Zip code 77650, serving the Port Bolivar community, contains just one school, Crenshaw Elementary And Middle, a small rural school within the Galveston Independent School District (Isd) that serves grades Pre-K through 8 with a total enrollment of 131 students.
Crenshaw Elementary And Middle presents a mixed academic profile with notable strengths and weaknesses. The school excels in Reading, particularly in 7th and 8th grades where proficiency rates of 73.68% and 54.55% respectively significantly outperform district and state averages. Science is another bright spot, with 8th-grade Biology proficiency reaching 72.73%, well above the district average of 59.39%. However, Mathematics is a consistent challenge, especially in upper elementary and middle school grades, with 5th-grade Math proficiency at just 26.32% and 6th-grade Math at 20%, both far below state averages. The school benefits from an exceptionally low student-teacher ratio of 7.9:1 and spends $18,245 per student, yet its state ranking has declined from the 56th percentile in 2023-2024 to the 16th percentile in 2025-2026, suggesting that the high poverty rate (77.1% economically disadvantaged) presents significant challenges that resources alone cannot overcome.
The school's small size of 131 students creates highly volatile data, where the performance of just a few students can dramatically swing proficiency percentages from year to year. For example, 6th-grade Reading proficiency dropped from 72.22% in 2024-2025 to 40% in 2025-2026, illustrating this sensitivity. Despite these challenges, the school maintains a 0.0% dropout rate, which is better than the district average of 0.3%. Parents should note that while Crenshaw Elementary And Middle offers strong instruction in Reading and Science with small class sizes, the school struggles significantly with Mathematics instruction and faces the broader difficulties common to high-poverty rural schools.
