Most public schools do not allow students to access YouTube, as of 2015. Depending on the school's firewall, students may be permitted to access YouTube with the permission of a teacher.
To encourage learning, many schools have firewalls that completely block a student's access to any social media or video viewing websites. However, many firewall systems installed by schools offer options that allow a student's account to view websites such as YouTube with the permission of his teacher. For example, some firewalls ask the teacher to enter his username and password to allow the student's account to view the website.
