Crystal Chang, daughter of  Patrick Chang and a sophomore at Diamond Bar High School, earned a top composite score of 36 on a recent ACT test.

Less than one-tenth of one percent of students who take the ACT earns the top score. Among test takers in the high school graduating class of 2013, only 1,162 of 1.8 million students earned a 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 ACT’s optional Writing Test, but the score for that test is reported separately and is not included within the ACT composite score.

In a letter recognizing this exceptional achievement, ACT CEO Jon Whitmore said, “While test scores are just one of the many 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.”

ACT test scores are accepted by all major U.S. colleges, and exceptional scores of 36 provide colleges with evidence of student readiness for the academic rigors that lie ahead.
