Science
Note:
 Standards are provided for each Science Test score range except the 1–12 range. Students who score in the 1–12 range are most likely beginning to develop the knowledge and skills assessed in the other ranges.
 Updates to the Standards in 2014 include:
 edits for specificity, concision, and clarity
 additions to include specific skills in multiple score ranges and to emphasize specific skills
 Sidebyside comparisons of the 2014 ACT College and Career Readiness Standards and the 2005 ACT College Readiness Standards can be seen by selecting “View changes.” In the popup windows, each standard is identified by a strand abbreviation and number. For example, the first standard in Interpretation of Data (IOD) is IOD 201.
