Five Criteria to Consider: CRAAP
1. Currency
Is the information
up-to-date enough
for my topic ?
Rapid advancements in
science necessitate
looking for very current
information

Example: Cloning

Van't Hoog, A., de Cock
Buning, T., &
Hazekamp, A. (2000).
Dolly's deceiving
perfection:
Biotechnology, animal
welfare, and ethics.
Journal of Applied
Animal Welfare
Science, 3(1), 63-69.
Five Criteria to Consider (cont.)
2. Relevance

Example: Obesity Epidemic

Is the information
relevant and in
enough depth to
meet my needs ?

Taking weight-loss pills
can make you eat
more. (2013,
November 19).
Daily Mail. p. 28.

[135 words]
Five Criteria to Consider (cont.)
3. Authority
Who is responsible
for the content and
what are their
qualifications ?

Example: Government Spending

Deller, S. C., & Chicoine, D.
L. (1993).

direct democracy: A
test of allocative
efficiency in local
government
expenditures. Public
Finance Review, 21(1),

doi:http://dx.doi.org/10.
1177/10911421930210
0105
Five Criteria to Consider (cont.)
4. Accuracy
Is the information
reliable and free
from error ?
Is the site free from
spelling and
grammatical errors
?

Are sources cited ?

Example: Aliens

Daniel P., W., & John
J., M. (2009). The
distribution of stars
most likely to
harbor intelligent
life. Astrobiology,
9(7), 617-621.
Five Criteria to Consider (cont.)
5. Purpose

Example: Gun Control

Is the information
presented without
bias or is the bias
acceptable for my
purpose ?

COULTER, A. (2012).
Trayvon and a
history of gun
rights. Human
