Student accounts are paid accounts that can initially try Storybird out for seven days with a free trial.
All student accounts require an email address (for ages 12 and under a parental email is required). An activation email will be sent to the address supplied, and once it's responded to the student account will become active.
Students can join classes by teacher invitation, Google Classroom, or by entering a Class Passcode that has been given to them by their teacher.
