Summary:
Zip code 76051 in Grapevine, Texas, is home to two high schools within the highly-rated Grapevine-Colleyville Independent School District (Isd): the traditional Grapevine High School and the innovative online/blended learning Iuniversity Prep, which serves grades 5 through 12.
The standout school in this area is Iuniversity Prep, which earns a 5-star rating and ranks in the 95th percentile statewide. It dramatically outperforms both the district and state averages in every core subject, with proficiency rates exceeding 95% in Biology, English I, and English II. The school also boasts a perfect 100% graduation rate and a 0.0% dropout rate. In contrast, Grapevine High School is a solid, above-average traditional school with a 4-star rating and a 78th percentile state rank. While it performs well in English and History, it struggles in core STEM subjects like Algebra I (55.9% proficiency) and Biology (63.29% proficiency), which are significantly below the district average.
The most compelling finding is the "efficiency paradox" of Iuniversity Prep. It achieves its elite academic results with a student-teacher ratio of 37.1:1 (nearly three times higher than Grapevine High School's 13.2:1) and a per-student spending of just $6,042 (nearly half of Grapevine High's $11,049). This suggests its blended/online model is highly scalable and cost-effective. Despite these stark differences, both schools benefit from being part of the same top-tier district, which provides a supportive framework that allows both a traditional and an innovative school to thrive.
