Students receive a scaled score for each of the four multiple-choice test sections (English, Math, Reading, and Science). A studentâs composite ACT score is the average of the studentâs scaled scores for the four multiple-choice test sections. Example: If a student scored a 24 English, 28 Math, 26 Reading, and 23 Science, his composite ACT score would be (24 + 28 + 26 + 23)/4 = 25.25, which is rounded down to a 25.
1 the typical ACT Composite score from the second testing was 21; 2  the middle 50% of students with an initial score of 20 received an ACT Composite score of 20, 21, or 22 the second time they took the test;  56% of students increased their scores, 21% scored the same, and 23% saw their scores decrease.
