Stockdale senior Aaron McKenzie earned the highest possible ACT composite score of 36.

 

Nationally, the average number of students earning a perfect score varies, with less than one percent notching a 36. According to the ACT, last year in 2015, only 1,598 of over 1.92 million students earned an ACT Composite score of 36.

 

The ACT consists of tests in English, mathematics, reading and science. Each test is scored on a scale of 1-36, and a student's composite score is the average of the four test scores. Some students also take the optional ACT writing test, but the score for that test is reported separately and is not included within the ACT Composite score.

 

"Your achievement on the ACT is significant and rare," said the ACT chief executive officer Marten Roorda in a letter to McKenzie. "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."
