High Schools in Mount Vernon Independent School District (Isd)

The Mount Vernon Independent School District (Isd) is home to a single high school, Mt Vernon High School, which serves 511 students in grades 9 through 12 in Mount Vernon, Texas. This school presents a mixed picture of academic performance, with standout strengths in specific subjects and a concerning decline in its overall state ranking over recent years.

Mt Vernon High School boasts an exceptional performance in Biology, with 93.55% of students proficient in the 2025-2026 school year, dramatically outperforming the state average of 70.51%. This is a clear area of excellence. However, the school struggles significantly in Algebra I, where only 44.16% of students are proficient, lagging behind both the district average of 59.48% and the state average of 54.03%. The school also shows mixed results in other subjects, slightly outperforming the state in English II Reading but underperforming in U.S. History and English I Reading. Despite these academic challenges, the school maintains a very high graduation rate of 95.5% and an extremely low dropout rate of 0.2%, suggesting strong student retention and support systems that help students complete their education.

A key takeaway is the school's declining trajectory in state rankings, dropping from the 67th percentile in the 2023-2024 school year to the 55th percentile in the 2025-2026 school year. This is a concern, especially since the district itself is ranked in the 70th percentile. The stark contrast between the school's Biology success and its Algebra I struggles points to uneven instructional quality across subjects. The high graduation rate, despite low proficiency in core subjects like Algebra I and English I, indicates that the school may be prioritizing student completion through effective credit recovery or alternative pathways, even as standardized test scores remain a challenge. For parents, this school offers a supportive environment for graduation but shows inconsistent academic performance that warrants attention in math and some reading areas.
