Summary:
In zip code 76012, there is one middle school, Shackelford J H, serving grades 7 and 8 with 510 students in Arlington, part of the Arlington Independent School District (Isd).
Shackelford J H presents a striking contrast in performance. On one hand, it excels in advanced coursework: it achieved a perfect 100% proficiency rate on the Biology STAAR EOC exam and a 77.94% proficiency rate in Algebra I, both far exceeding district and state averages. On the other hand, the school struggles significantly in grade-level core subjects, particularly 7th-grade Mathematics, where only 7.95% of students were proficient—well below the state average of 29.41%. This "two-schools" dynamic suggests a highly effective advanced track but a critical need for intervention in foundational math instruction for the general student body. The school's overall state ranking has declined from the 46th percentile to the 28th percentile over two years, likely because the ranking is heavily influenced by the majority of students' performance in grade-level tests.
Despite these challenges, Shackelford J H shows resilience in a high-poverty context, with 72.55% of students economically disadvantaged. It outperforms the district in 8th-grade Reading and has a lower dropout rate (0.8%) than the district average (2.1%). However, the massive year-over-year drop in 7th-grade math proficiency—from 31.94% to 7.95%—is a critical red flag that warrants immediate investigation. With a student-teacher ratio of 12.8 and per-student spending of $9,573, the school has resources to address these issues, but parents should be aware of the stark disparities in academic outcomes between advanced and grade-level courses.
