Here is a needs analysis questionnaire you may want to use with your EAP students when teaching presentation skills. I teach pre-sessional EAP in the UK and my learners are international students who are doing an MA. I based the questions on this particular context. You may be able to use it with your learners as well if you teach EAP presentation skills. This questionnaire can probably be used with Business English learners as well, after a few adaptations are made to some of the questions.
