Griffin White, son of David and Shelli White and a senior at Tesla STEM High School earned the highest possible ACT composite score of 36.

Griffin is also a National Merit commended student, which he obtained through his PSAT score. According to a release, Griffin is considering studying civil/forestry engineering.

On average, around one-tenth of 1 percent of students who take the ACT earn a top score. In the United States, in the graduating class of 2017, 2,760 out of more than 2 million graduates 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 the ACT’s optional writing test is reported separately and is not included within the ACT composite score, the release states.

In a letter to the Griffin recognizing his achievement, ACT CEO Marten Roorda stated, “Your achievement on the ACT is significant and rare. While test scores are just one of multiple criteria that most colleges consider when making admission decisions, your exceptional ACT composite score should prove helpful as you pursue your education and career goals.”

The ACT is a curriculum-based achievement exam that measures what students have learned in school.
