REALM Test
Accept / Reject?
REALM test only “worked” for 8 of
the 66 words
 It “failed” in 41% of a total of
8250 cases (125 respondents x 66 words)

FIP September 2002

Conclusion




REALM test is not a suitable tool to
assess health literacy in this population
Ability to pronounce words gives no
indication of comprehension
Schooling is an unreliable literacy
marker
Enables suitable terms to be identified
for inclusion in patient information
leaflets
