important steps in the process of evaluating information.
• CREDIBILITY – The quality and
capacity of belief.

for my research.
• Is the information affiliated with an
organization that has a particular
political or social agenda
Does this information help to answer my question?
Is it in-depth?
Is it too hard, too easy, or just right?
Yes or no answers are fine for the first part, then rate the level of the
Can it be eliminated or ignored because it simply does not help?
• DATE – The time at which an information

information on a given topic and the
reason behind its creation.
• Does this source address the thesis in
a comprehensive or peripheral way?
• Is it material that can easily be read
These questions should be posed each
time a research source is considered.
If the source does not pass any element
of the CARRDSS test, it should not be
Before blindly accepting whatever, you
find on the internet as fact, take the time
to review the information for CARRDSS.
