A parent or guardian creates access. We’ll email a temporary password to your address.
We ask for the child's first name so their Skhillz number belongs to them, and their age, grade and school setting. No surname, no email address, and no date of birth. Your learner's test notes stay on this device.
Enter the password we emailed you, or use the password you set after your first visit.
Use your six digit Skhillz number and the password your parent was emailed. Your number does not change, and it works for everything Skhillz.
Forgot it? Ask a parent. They can send themselves a new one from the Parent sign in tab.
