Who writes the articles to go in the magazine?

The articles that will go into the school magazine would mainly be written by students, but maybe some being written by teachers. The students writing the articles will probably in the higher years of the school, from around year 10 upwards, and will mainly consist of students that have an interest in writing, journalism, media or just want to promote an event or something happening within the school. By using students to write the articles, this helps the magazine to make sure it's targeting the right audience, as the students know who they're writing to the best, making it much more accurate than an older author guessing what their target audience wants from the magazine.
