What Is the Lowest Score on the ACT? The 1–36 Scale Explained
The lowest score you can receive on the ACT is 1. Because the ACT is scored on a 1–36 scale in whole numbers, a 1 is the absolute floor for both individual sections and the overall composite. So if you are asking what is the lowest score on the ACT, the answer is simply 1—there is no score below it.
The Lowest Possible ACT Score
On the ACT, each of the four required sections—English, Math, Reading, and Science—is scored on a 1–36 range. That means 1 is the lowest a section can go, and 1 is also the lowest possible composite. In practice, a 1 is extremely rare; most test-takers who complete the exam score well above the minimum. A composite of 1 would require near-total incorrect answers across all sections, and even then, scoring is based on a conversion that maps raw scores to scaled scores, so very low raw scores can still land slightly higher.
For perspective, if a student answered only a handful of questions correctly and left the rest blank, the resulting scaled scores would likely be low single digits or low teens—not necessarily a 1. The 1 exists on the scale, but it is the theoretical bottom, not a common outcome. The lowest score most students realistically encounter is somewhere in the low double digits or higher, depending on how many questions they attempt and answer correctly.
How the 1–36 Scale Works
The ACT uses a 1–36 scale for each section and for the composite. Your composite score is the average of the four section scores, rounded to the nearest whole number. For example, if you earned a 20 in English, 18 in Math, 22 in Reading, and 20 in Science, those four scores add up to 80. Dividing by 4 gives 20, so your composite would be 20.
Because every section shares the same 1–36 range, the lowest possible composite is also 1—but achieving it would require averaging 1 across all four sections. This structure is why the ACT is often described as a 1–36 test; the 1 is the floor, and 36 is the ceiling.

Key Takeaways
- The lowest possible ACT score is 1, on the 1–36 scale.
- Each of the four sections—English, Math, Reading, and Science—is scored from 1 to 36.
- The composite score is the average of the four section scores, rounded to the nearest whole number.
- A 1 is the theoretical minimum and is extremely rare in practice; most test-takers score higher.
