1. Choose a Job Objective.  An actual job title works best. 
   
2. Find out what skills, knowledge, and experience are needed to do that target job.
   
3. Make a list of your three or four strongest skills or abilities or knowledge that make you a good candidate for the target job.
   
4. For each key skill, think of three or four accomplishments from your past work history that illustrate that skill.
   
5. Describe each accomplishment in a simple, powerful action statement that emphasizes the results that benefited your employer.
   
6. Make a list of the primary jobs you've held in chronological order.  Include any unpaid work that fills a gap or shows that you have skills for the job.
   
7. Make a list of your training and education experiences that are related to the new job you want.
   
8. Choose a resume format that fits your situation, either chronological or functional.  (Functional works best if you are changing job fields; chronological works best if your are moving up in the same field.) 
   
9. Arrange your action statements according to the format you chose.
   
10. Summarize your key points at or near the top of your resume.
