If you forgot your password, you can request that your password be reset by contacting your child's homeroom teacher. Once the password is reset an email will be sent to your account you used to set up the SIS account.
You can go to the SIS site
and click on the "reset my password" link. Enter the login id which is the email address you used to create the account. (The login id and primary email will be the same information.) Enter this information and a password reset email will be sent to your email account.
