The highest possible ACT composite score is 36, and it is achieved by having the top scores on the four required sections: English, Math, Reading, and Science. The Writing section is optional and does not contribute to the composite score. A perfect composite score of 36 is quite rare, occurring in a small fraction of test-takers each year. Key points:
- Composite score maximum: 36. This is the average of the four section scores (each section scored 1–36).
- Individual section scores: Each of English, Math, Reading, and Science can individually reach up to 36, and the composite is their average rounded to the nearest whole number.
- Writing: Optional; does not affect the composite score. A student can receive a 36 composite even if the Writing score is not perfect or even completed.
-Rarity: A true perfect 36 composite is rare; historical data show only a small percentage achieve it in a given class, emphasizing its difficulty.
If you’re aiming for a 36, consider focusing on:
- Mastery in each section so no single section drags the composite down.
- Efficient test-taking strategies to maximize correct answers across sections, since there is no penalty for guessing.
- Practice with full-length, timed ACT exams to build endurance and pacing.
