On the upper right of your screen when you login, it will say "Current Student." From that drop-down, you can select a different student, or add one to your existing account. If you choose to add, you will need to obtain a Verification Code from your child's school office (SLC, building or GLLC).
Go to https://luhsd.asp.aeries.net/ and Click Create New Account. Complete the information requested to create your account. You need 3 pieces of information to create an account, the student ID, telephone number and Verification Code. The verification code can be obtained from the student's schedule provided at walk-through registration or contacting your school site to obtain the code.
Any school site secretary can provide that number to you. Just call the school site to request your verification code.
