This survey was conducted with the use of a questionnaire to investigate among 106 oral test raters their mastery of English intonation knowledge in terms of tonality, tonicity and tone. The results show that the raters do not have a good mastery of basic English intonation knowledge. Specifically speaking, most of them have the basic knowledge of tone groups, but they are unclear about the specific word categories which can be used as sentence stresses and nucleus. They are more familiar with tone types indicating request, affirmation, and demand than those of politeness, delight, and relaxation. This study offers some suggestions in two aspects: (1) teachers should consolidate their own intonation knowledge in order to set a good example for their students and secondary tone types should be paid more attention to in teaching; (2) oral test raters should receive regular intonation training to guarantee that they master basic intonation knowledge and different meanings conveyed by different tone types so that intonation will not be ignored in oral tests.
