Enter two ACT sittings and this calculator takes your best subject score from each and works out both superscores: the legacy four-subject method and the enhanced English/Math/Reading method ACT now reports.
| Input | Result |
|---|---|
| Sitting 1: 28/26/30/25, Sitting 2: 31/29/28/27 | Legacy 29, Enhanced 30 |
| Same scores in both rows (28/26/30/25) | Legacy 27, Enhanced 28 |
| Sitting 1: 20/18/22/19, Sitting 2: 24/21/20/22 | Legacy 22, Enhanced 22 |
Superscoring averages your best subject score from every attempt, not the scores from your best single day. ACT's own instructions are to gather your score reports, find the highest score in each subject column, and average those.
The important change is that the enhanced ACT superscore uses three subjects, not four. ACT states that composite scores on the superscore report are based on English, math and reading, while science is used with math to produce the STEM score. Your highest section scores can come from any test event, whether legacy or enhanced.
| Method | Subjects averaged | When it applies |
|---|---|---|
| Legacy | English, Math, Reading, Science | Sittings on the legacy blueprint |
| Enhanced | English, Math, Reading | The current method ACT reports for the enhanced test |
Both are shown above so you can see the difference on your own numbers rather than guess which one a college will use.
A superscore averages your best subject scores across every sitting rather than taking a single test date. ACT describes it as identifying your highest score in each subject, then averaging those best scores.
ACT changed the calculation. On the legacy test the superscore averaged English, math, reading and science. On the enhanced ACT it averages English, math and reading only, the science score feeds the STEM score instead. Your best section scores can come from any test event, legacy or enhanced.
Many do, but practice varies: some superscore, some take your best single sitting, and some require all scores. Check each college's testing policy before deciding whether a retake is worth it.
It depends entirely on how much your section scores move between sittings. If your best scores are spread across two dates, a superscore can add one to three composite points over your best single sitting; if one sitting was uniformly your best, it adds nothing.
