You finish the TEAS, click through the screens, and receive a result that looks like a percentage — but which percentage? If you answered 42 of 50 science questions, why didn't your science score show 84%? The answer lives in the difference between raw scores (how many you got right) and scaled scores (how that's translated into your reported result), and understanding the mechanics can completely change how you interpret practice tests, prioritize sections, and set a target.
The Two Scores
- Raw score: the literal count of questions you answered correctly in a section (e.g., 42 out of 50).
- Scaled score: your reported result, shown as a percentage from 0% to 100% per content area and as a total composite. ATI does not report the raw count publicly — it reports the scaled/adjusted value Source.
The Structural Fact That Changes Everything: 20 Unscored Questions
The TEAS 7 has 170 total questions, but only 150 count toward your score. The other 20 are unscored "pilot" questions ATI is field-testing for future exams — and you are never told which ones they are Source. Practical upshot: even a perfect-looking raw count must be reduced by however many unscored items you hit, so your raw percentage is always computed on a fraction of the questions you actually answered.
Equating: Why Two Forms Don't Score the Same
ATI scores the TEAS using equating — the reported percentage is "based on the percentage of items answered correctly but adjusted to account for differences in difficulty between different test forms" Source. In plain English: a harder form demands fewer correct answers for the same score; an easier form demands more. That's why your raw percent and your reported percent can differ by a couple of points — the adjustment is doing exactly its job: making a 72 reported on Tuesday mean the same thing as a 72 reported in March.
The Five Score Bands (Your Real Target Map)
Your adjusted percentage lands in one of five ATI performance bands used by nursing programs Source:
| Band | Adjusted % Correct | What It Means |
|---|---|---|
| Developmental | 0% – 40.7% | Below college readiness; heavy review needed |
| Basic | 40.7% – 58.0% | Approaching readiness; competitive programs will likely reject |
| Proficient | 58.7% – 79.3% | Meets basic college readiness; acceptable for many ADN programs |
| Advanced | 80.0% – 91.3% | Strong; competitive for most BSN programs |
| Exemplary | 92.0% – 100% | Top tier; ideal for the most selective schools |
What This Means for Your Strategy
1. Every section counts differently at every school. Some schools weight the total composite; others look at each content area separately against a minimum. Research your target program's exact requirement before setting a goal.
2. Don't chase raw count — chase band. Your goal is the band your program demands (e.g., "Advanced in all sections"). If you're consistently scoring 75–79%, you're minutes of study away from Advanced, not miles.
3. Practice-test scores are good approximations, not gospel. Third-party practice tests can't replicate ATI's equating adjustment perfectly, so treat a 76 on a practice exam as "around Proficient-high — fight for Advanced territory," not as an exact prediction.
4. The unscored questions are a stamina factor, not a strategy. There's no way to identify them, so treat all 170 as real on exam day — but know that missing 3 unanswered questions feels different now: because of equating and the unscored 20, "I left several blank" isn't the disaster it seems.
How to Read Your Official Score Report
Your ATI score report shows a total score plus four content-area scores (Reading, Math, Science, English & Language Usage), each presented as an adjusted percentage with its band. Some reports include your adjusted content scores as well as the academic-preparedness classification. Compare each section to your program's published requirements section by section — a single weak section can sink an otherwise great composite at programs that set per-section minimums.
Conclusion
The TEAS doesn't reward raw accuracy — it rewards band placement on an equated, partly-pilot-question exam. Know your target band, treat practice scores as directional, and stop panic-checking raw counts. If you're in Proficient territory, the gap to Advanced is smaller than it looks; if you're in Basic, the path is a defined list of weakest sections. Get your official report, map every section against your program's minimums, and build this week's study plan around the single section that's farthest below target — that's where your next band upgrade lives.
