No. GCU does not publish an official pass or fail similarity percentage for LopesWrite, and its support documentation sets no threshold. The widely repeated 20 percent figure is student lore, not GCU policy. A similarity score is not a plagiarism verdict on its own: quotations, citations, reference lists, and common phrasing all register, so faculty read the highlighted matches, not the number. Your instructor and the University Policy Handbook, not a magic percentage, decide whether a report is a problem.
What GCU actually publishes
Read GCU's own LopesWrite material and one thing is conspicuous by its absence: a number. The support documentation describes how a report is generated and where the similarity score appears, and it stops there. It does not name an acceptable percentage, a safe zone, or a cutoff at which a paper fails. That silence is deliberate. LopesWrite is built as a review tool that surfaces matching text for a human to interpret, not as an automated gate that passes or fails a submission at a fixed line. If you have been searching for the official GCU threshold, the honest answer is that there is not one to find.
Where the 20 percent number comes from
The 20 percent figure is everywhere on third-party study sites, quoted with such confidence that it reads like policy. It is not. It traces back to a common writing convention, the idea that a well-sourced paper is roughly its author's own words with only a small share given to direct quotation, and to individual instructor rules of thumb repeated until they hardened into folklore. A rule of thumb can be useful as a self-check, but treating 20 percent as a bright line leads people astray in both directions: they panic at a modest score built entirely of quotes and references, and they relax at a low score hiding one badly paraphrased paragraph. The number is a habit, not a standard.
What the score does and does not mean
The percentage tells you how much of your text matches sources in the LopesWrite database. That is all it tells you. It does not know whether a match is a properly quoted definition, your correctly formatted reference list, a common technical phrase, or genuinely borrowed analysis, and those cases are not equal.
| What registers as similarity | Is it a problem? |
|---|---|
| Quoted material inside quotation marks with a citation | No, that is correct attribution |
| Your reference list matching other reference lists | No, expected and unavoidable |
| Common phrases and standard terminology | No, language people share |
| Analysis matching a study-help site or another paper | Yes, regardless of the total score |
Because a score blends all of these, two papers with the same percentage can be worlds apart in integrity. The number is a starting point for reading, not a conclusion.
What faculty actually read
Instructors do not grade the headline percentage; they open the report and scan what is highlighted, asking one question of each match: should this text be identical to a source? A cited quotation, fine. A matching reference entry, expected. A paragraph of your supposed analysis lighting up against a homework site, a problem, even if the overall score looked low. Train yourself on the same question and the report stops being a verdict and becomes a proofreading tool: walk each highlight, justify it or fix it, and submit with nothing you cannot explain. The full method for reading a report the way faculty do lives in the LopesWrite manual.
Keeping a report clean, honestly
- Write from your outline with sources beside you, not from a source with your cursor inside it
- Quote sparingly and mark every quotation with its citation the moment it lands
- Paraphrase from memory after reading, then check accuracy against the source
- Never recycle work, including your own from a previous class, which trips the same wires
- Leave the fifteen-to-sixty-minute processing window so you can actually read your report
Synonym-swapping is the trap worth naming twice: shuffled source text stays structurally identical and reads as exactly what it is, so rewriting from understanding is the only real fix.
Where a tutor fits
The reliable way to make the similarity report boring is to write original work from the start, which is precisely how our support is built. A graduate tutor returns a premium original sample for your assignment in 24 to 48 hours, drafted fresh from current sources and mapped to the rubric, then run through an independent originality screen before it reaches you. You personalize it, send it through LopesWrite yourself, and read a report you already understand. The craft behind that, rubric first and report second, is spelled out in the rubric and LopesWrite method.
