The accuracy of data recorded by eight different observers over five observational tasks was investigated. The measures collected by each observer were compared with criterion values for each task. In addition, a coefficient of reliability was found for each observer by comparing his performance with that of the group. The results showed that the accuracy of observer recorded data was within the limits of acceptability and that the correlation between reliability and accuracy was moderately high.
