Evaluating Sources
EVALUATING SOURCES
At British University Vietnam (BUV), simply finding a source isn’t enough – you need to evaluate it critically. This guide equips you with practical strategies to assess sources using popular frameworks like the CRAAP Test and RADAR, helping you avoid unreliable information and strengthen your arguments with credible evidence.
Why Critical Evaluation Matters
Even when searching powerful databases like Google Scholar or ProQuest, not all sources are created equal. As highlighted in your course materials, “Your research is NOT the internet. Random websites are UNACCEPTABLE,” and “Not all sources are credible – it is your responsibility to ensure credibility.”
Critical Evaluation Helps You:
- Avoid biased or outdated information.
- Ensure the information is directly relevant to your topic.
- Confirm the source originates from a qualified expert.
- Verify the accuracy of facts and proper citation.
- Align your research with your assignment brief and rubric requirements.
Tip: Just because a source appears in a database doesn’t automatically mean it’s relevant or reliable for your specific assignment. Always apply critical thinking.
Applying the CRAAP Test
The CRAAP Test is a widely used framework to judge the quality and suitability of any source.
What is the CRAAP Test?
Is the information up-to-date?
Was it recently published or last updated? For fast-changing topics (e.g., AI, health), recent publication is essential.
Does it relate directly to your topic?
Is the source appropriate for your assignment level? Avoid sources that are too basic or too advanced.
Who is the author?
Are they an expert in the field? Are they affiliated with a credible institution (e.g., university, research center)?
Is the information supported by evidence?
Are sources cited? Can the information be verified? Look for peer-reviewed or fact-checked content.
Why was it written?
Is it objective, or is it biased? Watch out for sources that aim to persuade, sell, or entertain rather than inform.

An alternative way to evaluate sources is the RADAR Framework, especially useful for online material.
What is the RADAR?
Does this source support your argument or answer your research question?
If it’s only loosely related, it may not be strong enough for academic use.
Who wrote this? Are they qualified or affiliated with a credible institution?
Look for authors with academic credentials or professional experience.
When was it published? Is it still current?
For fast-changing topics (e.g., AI, health), only recent sources are acceptable.
Is the layout professional? Is the language formal?
Poor design, spelling errors, or informal tone may indicate low credibility.
Why does this source exist? Is it selling something or presenting facts?
If it’s trying to persuade or sell, it may be biased.

Each type of source comes with its own strengths and weaknesses. Understanding these helps you apply evaluation frameworks effectively.
Journal Articles
- Ideal for original research and peer-reviewed content
- Best for in-depth analysis and academic rigor
- Apply the CRAAP Test to ensure quality
- Be cautious of open-access journals with low “impact factor”
Example: “Digital Marketing Trends in Southeast Asia,” Journal of Marketing Research
Books & eBooks
- Great for theoretical background and long-term perspectives
- Provide comprehensive foundational knowledge
- Older editions may be acceptable depending on topic
- Verify publisher reputation and author credentials
Example: Burns, T. & Sinfield, S. (2008). Essential Study Skills
Websites
- Use with extreme caution — even reputable ones
- Always check purpose, author, and date accessed
- Never use: UKEssays.com, Coursehero.com, Studentshare.com
Warning: “These are all borderline plagiarism.”
Reports (Gov, Industry, Company)
- Provide valuable real-world data and statistics
- Often contain current data and practical insights
- Apply the RADAR Framework to assess quality
- Ensure it’s from a trusted, authoritative organization
Example: World Bank Report on Economic Growth in ASEAN (2024)
Student Papers or Blogs
- May offer interesting ideas, but not academic sources
- Use only for brainstorming or personal reflection
- Never cite student blogs or unverified posts
Tip: Feel free to use for idea generation, but never for referencing.
Using a Source Evaluation Checklist
To help you organise and apply what you’ve learned, here’s a structured checklist that supports effective evaluation.
Source Evaluation Checklist:
- Identify the source type (e.g., journal, blog, government report).
- Apply the CRAAP Test or RADAR Framework.
- Cross-reference with other credible sources.
- Note any potential bias, outdated info, or limitations.
- Make a final decision on whether to use it.
Tip: Use this checklist in conjunction with the CRAAP Test Worksheet to maintain focus and thoroughness.

Open the WorksheetTips for Evaluating Online Sources
Some websites may appear credible but are not. Here’s how to spot the difference and ensure you’re using reliable online information.
Evaluate Website Credibility by Asking:
- Who wrote it? Do they have authority or expertise on the subject?
- What is the domain? Domains like .gov, .edu, and .ac.uk are generally more reliable than .com or .net.
- When was it published? Is the information recent enough for your needs?
- Why was it written? What is the site’s purpose (to inform, persuade, sell)?
- Where did the information come from? Are sources cited within the website content?
Domain Credibility Sorter
Drag each domain to the category that best describes its type and credibility.
BUV – Domain Credibility Sorter
Instructions: Drag each domain to the category it belongs to. Use what you know about top-level domains (TLDs) to make your decision.
Domains
Categories
Academic institutions (e.g., universities)
Official government bodies (e.g., usa.gov)
Non-profit organisations (e.g., WHO, Red Cross)
Businesses, personal sites, or general use
Spotting Bias and Weak Arguments:
It’s crucial to recognise bias and weak arguments, even in scholarly work. As your study materials state: “Bias is when a statement reflects a partiality, preference, or prejudice,” and “Everyone has bias. Therefore, it’s important that you minimize the influence of your own biases.”
Questions to Ask Yourself:
- Is the source objective, or does it present a one-sided view?
- Is there a balanced perspective when considering counter-arguments?
- Is the data presented accurately, without manipulation or misinterpretation?
- Does the author acknowledge limitations in their research or argument?
Tip: Even scholarly sources can have biases. Always compare information across multiple sources to get a well-rounded view.
