Paper and on-line testing of graphical access symbols in three countries using the ISO 9186 comprehension test

Graphical symbols intended to indicate Priority facilities and Priority seating for those with limited mobility were tested in Japan, Australia and the United Kingdom using the ISO 9186-1:2007 comprehension test. Screen presentation was used in some circumstances, paper booklet presentation in others. Results from the three countries demonstrate a high level of agreement and also that the two methods of administration had no detectable influence on results. The need to have clear agreement on response scoring to obtain international scoring consistency was shown. The use of testing as an aid to symbol redesign is discussed.
