The ACT examination tests students in four areas: English, mathematics, reading and science. Before admission to many colleges, potential students must take ACT tests and submit their scores as part of the application process. Scoring of ACT tests involves assessing each test and then calculating a composite ACT score. According to the ACT website, the 2010 national average composite score was 21.0.

### Step 1

Find the individual test scores you earned for each of the four components of the ACT test. Find these scores on the documentation you receive in the mail from the ACT testing office.

### Step 2

Add each score together to find the total. For example, if your English score was 24.3, your mathematics score was 22.4, your reading score was 26.4 and your science score was 23.1, add these four numbers together to equal 96.2. This is your total score.

### Step 3

Divide the total score by four to find the composite score. Using the same example, divide 96.2 by 4 to get 24.05.

### Step 4

Round your answer either up or down, depending on the fraction. If a fraction is less than one-half, round it down, and if the fraction is one-half or greater, round it up. Using the same example, round 24.05 down to 24.
