One tip for creating a writing sample for an assessment is to follow instructions provided by the employer, and ask questions if there are any concerns, as this shows the applicant is proactive in seeking advice. If there are no specific requirements, use the job posting as a guide.
If the employer does not designate a topic for the writing sample, the applicant should chose a topic interesting to him, but avoid topics that are controversial or political in nature. If applying for a job straight out of school, it is acceptable to use a school paper or an excerpt from a school paper as a writing sample. However, for those who have been out of school for some time, using an old school paper tells the employer the applicant has not written anything worth noting recently.
