According to the website, "Members of the Scholastic News Kids Press Corps cover news stories for scholastic.com/news and select Scholastic classroom magazines. The program is open to all students ages 10-14 with a desire to be a journalist. The selection of Kid Reporters is based on writing ability, interviewing skills, and attention to detail."
