Summary:
The Clifton Independent School District (Isd) is served by a single high school, Clifton High School, which educates 311 students in grades 9-12 and is located in a community where just over half of the students (52.73%) are economically disadvantaged.
Clifton High School presents a mixed picture of strong achievements and significant challenges. On the positive side, the school boasts a perfect 100% graduation rate and a 0% dropout rate for the 2023-2024 school year, a remarkable accomplishment. Academically, the school excels in Biology, with 84.06% of students proficient compared to the state average of 70.51%, and also performs well in English II Reading (66.22% vs. 59.88% statewide) and U.S. History (77% proficient). However, the school faces a critical crisis in Algebra I, where only 15.15% of students are proficient—a staggering 38.88 percentage points below the state average of 54.03%. This single subject appears to be the primary driver behind the school's recent drop in state ranking, falling from the 74th percentile (4 stars) in 2024-2025 to the 58th percentile (3 stars) in 2025-2026.
An interesting anomaly in the data reveals that while the school's test scores in Biology, English I, English II, and U.S. History are identical to the district's scores (as expected for a single-high-school district), the Algebra I school score (15.15%) is significantly lower than the district score (25.97%). This mathematical impossibility suggests that students from other campuses within the district—likely middle schoolers—are performing much better on the Algebra I End-of-Course exam than the high school students. This tension between a perfect graduation rate and low proficiency in core subjects like Algebra I (15%) and English I (52.5%) raises important questions about whether the school's curriculum prioritizes credit completion over mastery of state-tested standards.
