You would want to keep it simple and focus on the skills that you use on a daily basis.
At the top of your resume, ensure that you have up-to-date information (contact number, email and home address). Next, you would want an objective. This is where you would let the potential employer know what you want and the traits that you can bring to the job.
The next section could be your volunteer/community experience. If you've done work experience through a course at school, make note of it here. If you've had odd jobs or done things like babysit or yard work for neighbours, list it here. If at all possible, get letters of reference.
Next, list course work at school that you feel is relevant to the job. Make note of any academic achievements or awards. Explain how you think your excellent performance in these areas would benefit the employer or enhance your ability to do the job. If you can, get a letter of reference from a teacher of one of the courses you mention.
List your extracurricular activities of a non-volunteer nature such as sports, church or youth groups, school committees, etc. If you have a position that demonstrates leadership in any of these groups, make note of it here and describe your duties as if they were a job.
Finally, sell yourself by making a list of your skills, special talents or positive personality traits.
