The world is constantly changing, and so are our beliefs about it. That is why we need to establish an independent mindset and critical thinking to rely on. Originality in our manifestation, including writing, is a crucial part of it. That is why educators and content creators need to check their papers for similarity to avoid plagiarism.
What percentage of plagiarism is acceptable? The question is worth 10.3 billion search results. Well, to those looking for a simple answer: no, there’s no single benchmark. Or could zero plagiarism count? Different universities, colleges, and high schools have different standards. What is good and allowed for one, will be a red flag for another one.
Mostly, no more than 20% of text coincidence can be tolerated, while more means the text is not original. Although, even if that 20% is just a single copy-pasted piece of text, it’s considered borrowed.
What percentage of plagiarism is acceptable at university
How much plagiarism is allowed also depends on the type of the paper. The acceptable percentage varies within the limit of the mentioned 20%. Each case is individual, and the educational institution, the teacher, and the nature of the detected similarities should be taken into account. However, obviously, how much plagiarism is allowed in research paper differs when we talk about a regular essay or a dissertation.
Type of content | What percentage of plagiarism is acceptable |
General academic writing | 15-20% |
Essays | 20-25% |
Thesis and dissertations | 5-15% |
Published journals | 5%-15% |
Research papers | 20-25% |
Term papers | 15-20% |
One should keep in mind that the similarities found may be unintentional plagiarism. It happens that the students accidentally copy someone else’s ideas out of pure coincidence or based on the resources they have studied without realizing they are repeating the information.
That’s why if you notice plagiarism in your student’s work, it’s time to talk to them, figure out the reasons, and map the possible ways out. To help you do this, we’ve prepared a checklist you can share with your students. You can send it to them the way it is, or use it as an inspiration to create your own one—it’s up to you.
Why one needs to look out for plagiarism
Why tools like Turnitin and PlagiarismCheck.org are in demand and do all professionals need them?
- The consequences of plagiarism are drastic in academia and the professional and creative world. Doctorate revocation, expulsion, losing a job, money loss, and legal issues are only several of a long list of unveiled cheating repercussions.

A Comprehensive Checklist on How to Avoid Plagiarism
The obvious answer is to produce original content. But cases might differ, so check out a few tips to polish your writing.
#1. Avoid Direct Quotes and Paraphrasing
First, say your goodbyes to copy-pasting or rephrasing someone else’s thoughts. Instead, read different sources of information on your topic, jot down key points, and then write their essence in your own words. Examples:
| According to NASA, “Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.” | Global warming is the term used to describe the gradually raising temperature because of burning coal, oil, gas, and some other natural gases, like methane, nitrous oxide, and water vapor. They create an additional layer in the Earth’s atmosphere that traps the heat and causes the “greenhouse effect.” |
Simple steps to paraphrase without plagiarism:
- Comprehend, analyze, and conclude. Process the information you get from the source and focus on using it to enhance your paper. Rely on ideas, not wording.
- Study and compare the sources. The more resources you consult, the more comprehensive, informative, and objective your writing will be. It will also be easier to reflect on the subject in your own words!
- Add a sparkle of individuality. Think of the value your work brings to the reader. Find ways to elevate it with your own reflections, examples, or experiences.
- Cite the sources. Remember, even when you don’t quote someone’s work, you need to cite all the sources you’ve used for reference. Otherwise, the paper will be considered plagiarized, no matter how good your paraphrasing is.
- Use AI moderately. AI tools can significantly elevate your working routines if introduced ethically. Incorporate them for brainstorming, double-check any information you get, and cite AI as a source when you use it.
- Check for originality. It’s better to double-check than risk being accused of plagiarism. Use similarity detection tools to ensure your paraphrasing is appropriate and the paper is original.
#2. Proper referencing
Oh, the favorite part, we know. With all those formatting styles driving you mad, citing the sources might be the most boring and difficult part of your academic assignment. Yet, it’s inevitable to differentiate your work and someone else’s research you studied to support your claims. To make your life easier a bit, the Purdue University systematized guides on each popular citation style: MLA, APA, Chicago, AMA, ASA, and IEEE. If you still find those difficult to figure out, you can try using a citation machine instead. All you need to do is to choose the necessary style, specify the type of source, fill out relevant fields, and copy-paste the result. For instance, here’s how it helped to cite a source in the APA citation format: National Geographic Society. (2023, February 6). Global Warming. Retrieved February 6, 2023, from https://education.nationalgeographic.org/resource/global-warming
Mind that improper citing also counts as plagiarism. Here are several examples of cases when the sources are cited but in a misleading way.




#3. Proofreading
To err is human. Spotting and fixing the mistakes (and learning from them) can make you superhuman. Double-checking the text can enable you to find those “Oh, I’ve already read it somewhere” parts. Here, we mean that sometimes you can mimic your own style, even not knowing that. Reviewing the same content after a while can help you have a fresh look at it and find those self-plagiarized sentences or paragraphs. It can also allow you to discover tricky referencing issues when you might have missed citing something properly. In case you don’t trust yourself, ask one of your mates to review your paper.
#4. Using AI ethically
AI tools can help with brainstorming but should never be used to compose the paper instead of student. AI abuse violates academic integrity and also leads to AI plagiarism which can be detected by modern plagiarism checkers.
#5. Enriching vocabulary to avoid clichés
Another common reason for plagiarism is using the same phrases you can come across on thousands of websites. It’s not about some industry-specific terms you might desperately need in your physics, nursing, marketing, or any other assignment. We mean rather generic phrases and idioms like “as easy as a pie,” “sky’s the limit,” “sad but true,” etc. Not to mention some of them might be inappropriate for academic writing, if you overuse them, they’ll drop your content originality. To avoid that, we recommend:
- Reading more books, scientific journals, and so on to expand your general knowledge and vocabulary, as a result.
- Jotting down new words and phrases you haven’t known before and trying to use them in your speaking or writing. If applicable, of course.
- Using synonyms to eliminate tautology. You can find some good ones in the Thesaurus, or Power Thesaurus. Feel free to use those tools whenever you see some repeated words or idioms.
#6. Scanning texts with plagiarism checkers
To be on the safe side, we would advise checking your paper with specialized tools, like PlagiarismCheck.org before submitting it. This will help you make sure you’ve produced an original piece of content. A huge plus of such tools is that they can define all possible types of plagiarism, including copying your own style. For example, PlagiarismCheck.org delivers a report with highlights of the matching parts and links to the sources those pieces of text come from.
Let’s wrap it up
If we come back to our initial question: “How much plagiarism is allowed?”, the answer is still “None in a perfect world.” Yet, we live in reality, so up to 20% might be tolerated. We suggest minimizing even those numbers by educating your students on how to produce unique content.
Anyways, if you need to scan for plagiarism, try PlagiarismCheck.org. We’ve built it with academic integrity in mind, so it includes AI checker GPT and can spot ghostwriting by comparing student’s writing style from previous works and the current ones.
