Summary:
In the 78410 zip code of Corpus Christi, Texas, four elementary schools serve students from Pre-Kindergarten through 5th grade, all part of the high-performing Calallen Independent School District (Isd), which ranks in the top 25% of Texas districts.
The standout school is Calallen West Intermediate, a 4-star school serving grades 3-5 that leads the area academically. Its state ranking has climbed from the 64th to the 81st percentile, and it consistently outperforms district and state averages—for example, 71% of 5th graders were proficient in math versus 47% statewide. In contrast, Wilma Magee Intermediate, also serving grades 3-5, is the lowest-performing school with a 2-star rating and declining rankings. The performance gap between these two intermediate schools is stark: Calallen West outperformed Wilma Magee by an average of 18.5 percentage points across all tested subjects. The two primary schools, Calallen East Elementary and Calallen Wood River Elementary, serve PK-2nd grade and lack test score data, but their free/reduced lunch rates (77% and 52%) suggest they serve different socioeconomic populations that likely influence later performance.
Key metrics show spending per student is uniform ($9,718-$10,265) and student-teacher ratios are favorable (12.4:1 to 14.2:1), so resource allocation doesn't explain the performance gap. The percentage of students receiving free/reduced lunch varies widely from 45% at Calallen West to 66% at Wilma Magee, strongly correlating with academic outcomes. A notable finding is that 5th grade science scores were the lowest subject area across both intermediate schools, indicating a district-wide area for improvement. Overall, a student's academic experience in this zip code depends heavily on which intermediate school they attend, despite being in the same district.
