Sleeping Well, Eating Breakfast, and Feeling Calm:

Experiences Related to ACT Scores

We asked students, each of whom had taken the ACT twice, several questions about particular physical and emotional experiences that could be related to test performance. The figure below illustrates several findings:

  • Students who reported sleeping 7–10 hours the night before the second test earned ACT Composite scores that were about one point higher, on average, than their scores on the first test. This average score change is noticeably larger than the average Composite score change of 0.5 points for students who slept relatively little (0–3 hours) the night before the second test.
  • Students who reported eating breakfast before the second test had larger average ACT Composite score changes (about 1.0 points) from the first to the second test than did students who reported not eating breakfast (0.7 points).
  • Students who reported having no trouble finding the testing site for the second test outperformed those who did have trouble and who also reported thinking that this experience hurt their test performance (average Composite score change of 0.9 vs. 0.4 points, respectively).
  • Students who reported feeling so stressed or anxious while taking the second test that they believe it affected their performance had smaller average Composite score changes (0.7 points) than did those who reported not feeling this way (1.2 points).
