Estimation scores of comprehensibility were obtained for 109 hospital symbols, divided over five different sets. These scores were compared with the results of a comprehension test of those symbols. It is shown that the estimation scores can be used in a reliable way to identify good and bad symbols at an early stage. It is further demonstrated that the number of symbols to be tested for the ISO testing procedure can be substantially reduced.
