The main SchoolBase login screen requires you to put in your school's domain, your user name and password. If you have got to SchoolBase through your school's website, the domain name will probably be filled in for you, and you will probably see your school's logo rather than the SB logo pictured here. If you are not provided with the domain, it should be in the login information the school sent to you. 

Please enter the school domain, your user name and your password then press Login to get to your main menu. 

If you have forgotten your password you need to talk to the IT support people at your school. The red 'Forgot Password?' message is just for parents, as pupil and staff accounts are managed in school.
