Use a template that clearly identifies each separate category of information you wish to convey. As a minimum you should address the following:
If there are predefined selection criteria associated with the position ensure that you address each of them in a separate section of the document. If there isn’t any selection criteria make sure you include a section on why you think you can do the job and why the prospective employer should hire you. This is often included in a covering letter rather than the body of the Resume.
