You passed the PMP exam. You saw the preliminary result and celebrated. Then days later an email arrived that your score has been canceled....
You just had an ACT score cancellation. You opened the email or letter, and now you’re being told your answers looked too similar to another student’s. Or it could be that a proctor flagged your behavior, or the system detected something it didn’t like.
You’re panicking, and you don’t know what happens next.
This guide will walk you through exactly what ACT does when it suspects cheating. We will tell you exactly how to fight a wrongful accusation, and if you did take a shortcut, how to make sure you never end up in this mess again.
Why the ACT Cancels Scores
The ACT doesn’t need to catch you red-handed. It uses statistical analysis, proctor reports, and post-exam forensics to identify possible cheating.
Here are the main reasons that get an ACT score invalidated:
- Answer similarity analysis. This is the big one. The ACT compares your answer sheet to every other student who took the same form on the same date. If your wrong answers and right answers line up too closely with someone sitting near you, the system flags it. Even if you never looked at another paper, a high similarity score will trigger an investigation. The ACT does not need proof you cheated. It only needs the statistical anomaly to justify canceling your score.
- Proctor report. If a test center proctor saw you looking around, using a phone, passing notes, or behaving suspiciously, they file a report. That report alone could lead to a cancellation. The proctor doesn’t have to prove anything. Their word is enough to start the process.
- Device monitoring in the online ACT. If you took the ACT online, the software tracks your screen. It also monitors your webcam and your keystrokes. If you opened another window, tried to copy text, or your eyes moved off-screen too often, the system flags those behaviors. Those flags go to human reviewers, who will often recommend cancellation.
- Score gain analysis. Less common, but if your score jumps dramatically from a previous test (like a 10-point increase), the ACT may review your session. A big jump alone isn’t enough, but combined with other flags it can tip the scales.
What Happens After You’re Flagged
You won’t just see a canceled score with no explanation. ACT sends you a letter or email outlining the issue and your options. Typically, you get one of three choices.
- Retake the exam for free. ACT often offers a free retake if you agree not to contest the cancellation. This is the fastest way to get a new score, but it means the flag stays on your record.
- Request arbitration. You can challenge the decision through an arbitration process. This is a formal review where you present evidence that you didn’t cheat. It’s slow and rarely successful because ACT doesn’t have to prove cheating beyond a reasonable doubt. They just have to show their process was reasonable.
- Cancel the score yourself. If you know you cheated or you don’t want the headache, you can accept the cancellation and move on. This leaves a mark on your ACT record that some colleges may see if you apply later.

What to Do If You’re Actually Innocent
If you didn’t cheat and your score got flagged, you need to move fast. Here’s the path to fight it.
- Step 1: Don’t panic and don’t ignore it. The clock is ticking; hence, you usually have a limited window to respond. This is often two to four weeks. If you miss it, your score gets canceled by default.
- Step 2: Gather every piece of evidence. Write down everything you remember about test day. Where you sat and even who was near you. What you did during breaks. If you have time-stamped receipts, school attendance records, or anything that shows you were in the room the whole time, collect it.
- Step 3: Request a copy of your test materials and the specific evidence against you. Under the ACT’s policies, you may be able to see the proctor report and the similarity data that triggered the flag. Demand it. If they won’t give it to you, say you need it for your appeal.
- Step 4: Write a formal appeal letter. For this, keep it professional and factual. Explain that you did not cheat, you understand the seriousness of the accusation, and you request that your score be reinstated. Include your evidence and ask for a written response within a specific timeframe.
- Step 5: Consider legal help. If you’re facing a college admission deadline or scholarship loss, an attorney who deals with education law or ACT cheating accusation help could sometimes pressure a faster review. This won’t work for everyone, but a lawyer’s letter can get their attention.
The ACT Appeal Process: Step by Step
If the ACT gives you the option to appeal, here’s how it usually works.
- You submit a written appeal. This goes to the ACT’s Test Security division. You explain why the cancellation is wrong and include all your evidence.
- ACT reviews the case. A committee or a single reviewer looks at the proctor report, the similarity analysis, and your appeal. They don’t have to prove you cheated; they just decide if their original decision was reasonable.
- You get a decision. Most appeals are denied. That’s the harsh truth. ACT wins the vast majority of these cases because the standard of proof is low for them and high for you.
- If denied, you can request arbitration. This is a more formal process, but still not a court trial. An arbitrator reviews everything and makes a binding decision. It’s rare for a student to win.
- If you win, your score is reinstated. This happens occasionally, usually when the proctor report was clearly wrong or the similarity analysis was based on a seating chart error.
If You Did Cheat (or Are Considering It): The Smarter Path to Avoid ACT Score Cancellation
If you’re reading this because you actually did cheat and got caught, the appeal process won’t help you. ACT has evidence, and fighting it will only waste time and draw more attention. Your best move now is to accept the cancellation, take the free retake if offered, and make sure the next attempt doesn’t end the same way.
