Most students have many activities to add to their resumes. Include their role, as well as the organization, i.e. Captain, JV Basketball. Also some students are involved in private study of music, athletics or other special interests. Most students have had at least a couple of jobs. No matter now unimportant they seem, the jobs will demonstrate the ability to get to work, manage both work and school, and communicate with the public.
Most students have community service to add to their resume.
Or this can be written as an interest. All students have soft and hard skills. After teaching resume writing about 10 times in this format, I added more samples and exercise pages and created my book 130 page book, Creating Your High School Resume.
