To examine interrater reliability of the Ruff Figural Fluency Test (RFFT), 124 college students completed the RFFT and scored RFFT test protocols. Three questions were examined: (a) What is the relationship between RFFT scores obtained by different raters? (b) Do participants improve in RFFT scoring accuracy with practice?, and (c) Are participants who perform better on the RFFT more accurate raters? Interrater reliabilities for unique designs, design perseverations, and error ratios were .93, .74, and .66, respectively. Participants benefitted from practice on scoring with increased accuracy over five protocols. Finally, results indicated a positive relationship between performance on the RFFT and scoring accuracy.
