Four faculty members in removable prosthodontics participated in a three‐phase rater training program. Nine complete dentures were given an overall rating by three outside experts to obtain an accuracy measure. A three‐point rating scale was used: R (cannot be appreciably improved), S (clinically acceptable), and T (clinically unacceptable). During the pretraining phase, the average interrater reliability was .57 as estimated by intraclass correlation, and the mean accuracy correlation was .76. The rater training phase consisted of a four‐hour session including presentations and discussions of rating terminology and formats, observer accuracy, and related issues. In the post‐training phase, the same nine complete dentures were rated by the four faculty members, using the same three‐point rating scale and a five‐point scale. The average post‐training interrater reliabilities were .56 and .76 on the three‐ and five‐point scales, respectively. The mean accuracy correlation was .78.
