Computer trainers instruct new users on the latest software or hardware. They are usually expected to prepare materials for instructions and may be asked to write and maintain a course manual. A position may also include design and development of a website for the course.

Employers look for trainers with good communication skills and teaching experience. Though a technical degree may not be required, it may be preferred. Experience with the latest software and/or hardware is essential but this varies depending on the position. Applicants who are comfortable speaking in front of groups may be preferred.
