South High's Louisa Lehmann achieves perfect ACT score

Louisa Lehmann6/10/2021 -- Louisa Lehmann from South High School recently learned she scored a 36 -- the highest possible score -- on the ACT college admissions and placement exam. She took the ACT in April.

Lehmann just finished her junior year at South High and wants to attend Maryville University and plans to study actuarial science. She expects to be an actuary after college. Outside of school, Lehmann enjoys reading, baking, painting and biking.

Nationally, while the actual number of students earning the top score varies from year to year, on average, fewer than 1% of students who take the ACT earn a top score. In the U.S. high school graduating class of 2020, only 5,579 out of nearly 1.67 million students who took the ACT earned a 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 score for ACT’s optional writing test is reported separately and is not included within the ACT composite score.

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.
