Of particular importance are experiences illustrating leadership potential, organizational ability, communication skills, ingenuity, and teamwork. Use action verbs. The employer wants to know the relevancy of this job to what you are applying for. If not, think twice about including it here. Include all community and service related activities you were involved with in high school or are presently involved.
Volunteer work is important to include here.
Resumes are by their nature summary documents, but this section takes the synopsis another step toward brevity. It isolates the four or five key attributes you claim as a graduate, worker or trainee. It gives the employer a glimpse, in just a few lines, of your primary qualifications. And, as is the style of a reverse chronological document, the summary comes first or near the top of your resume. Usually, a summary is placed directly above the education, but could go below as well.
