Maumelle High School student earns perfect score on ACT

Maumelle High School’s Eva Casto earned the highest possible ACT composite score of 36.

Eva Casto, a 15-year-old sophomore at Maumelle High School, earned the highest possible ACT composite score of 36.

Casto has taken the ACT three times, the first as a seventh-grader where she scored a 28. She took it again last year when she was in ninth grade and received a 31. During the December exam, she earned a perfect 36. 

Eva credits her success to the teachers at Maumelle High School and her parents. Her mother, Cindy Casto, is a teacher at Maumelle High School and Maumelle Middle School.

In a letter to the student recognizing this exceptional achievement, ACT CEO Marten Roorda stated, “Your achievement on the ACT is significant and rare. Your exceptional scores will provide any college or university with ample evidence of your readiness for the academic rigors that lie ahead.”

Fewer than half of 1 percent of students who take the ACT earn a top score. In the U.S. high school graduating class of 2019, only 4,879 out of nearly 1.8 million students who took the ACT earned a top composite score of 36.

The ACT consists of tests in English, mathematics, reading and science, each scored on a scale of 1–36. A student’s composite score is the average of the four test scores.

The ACT is a curriculum-based achievement exam that measures what students have learned in school. Students who earn a 36 composite score have likely mastered all of the skills and knowledge they will need to succeed in first-year college courses in the core subject areas. ACT scores are accepted by all major four-year colleges and universities across the U.S.
