The survey reported in this document was undertaken to determine the experience and opinions concerning written technical communications of prominent and successful engineers in a wide variety of engineering fields. A questionnaire sent to 245 engineers asked 11 specific questions, 8 of which dealt with the respondents' own experiences and the writing necessary in their positions (the amount done, its importance, and its effect on their own and others' advancement) and 3 of which dealt with the respondents' opinions about courses in technical writing in scientific and engineering curricula. Replies were received from 73.6 percent of those surveyed and indicated that respondents spend 24 percent of their time writing, the writing is very important to their positions, and the ability to write effectively has helped them in their own advancement. In addition, 80.5 percent feel that technical writing (clear, direct, and logically developed) should be required of all engineering students, while 16 percent feel it should be an elective course.
