Structure
40 multiple-choice questions arranged across passages that require interpretation of tables, graphs, and experimental design descriptions.
The section gauges a student's ability to read graphs, evaluate experimental design, and synthesize scientific information—skills relevant to college-level STEM coursework and placement.
Students, educators, and institutions rely on the ACT Science score to measure scientific reasoning and inform academic decisions.
Individual use varies: students use scores for self-assessment and test strategy; institutions use aggregated data for curriculum planning.
40 multiple-choice questions arranged across passages that require interpretation of tables, graphs, and experimental design descriptions.
Data representation, research summaries, and conflicting viewpoints that emphasize analysis over memorized facts.
35 minutes total; pacing strategy is essential because questions are dense and time per item is limited.
Raw score converts to a scaled subscores 1–36; section contributes to composite ACT score when reported.
Interpreting experimental results, evaluating hypotheses, identifying trends in graphical and tabular data.
Administered in test centers; some districts and schools offer ACT School Day or approved computer-based formats.
