Applications for all roles are open until the 10th of the month - we encourage you to apply for as many positions as you're interested in, even if you're fairly new to the site. You must be at least 18 to apply for auror/professor, at least 16 to apply for gamekeeper/muggle liaison, and at least 13 to apply for prefect. (There are no age restrictions for house newsletter editors.) We'll notify you one was or the other by the end of the month you apply in - if we don't offer you a position immediately, we'll keep your application under consideration for an additional two months. After that, you'll need to apply again.
Please only answer questions applicable to roles you're applying for. If you'd like more information about the process and/or what each role entails, please check out our blog entry here:
