    1. Ensure all the information in your Skew The Script account is complete and up-to-date. Specifically, please verify/update all fields marked “Required” in your member account, using this link. If any required fields are missing, fill them in and click “Update” at the bottom. Note: If you are not already logged in to your account browser, the link will prompt you to log in.

      • Option 1 - Instructor/Teacher ID

        • Email verify@skewthescript.org from your school email address with a photo of your official school ID. Please ensure that your name and school name are clearly visible.

      • Option 2 - Staff Directory

        • Email verify@skewthescript.org from your school email address and provide a direct link to your school’s official staff directory page where your name and position are listed.

      • Option 3 - Administrator Confirmation

        • Have your school’s principal, department char, or an administrator email us from their school email address at verify@skewthescript.org to confirm your current employment as a teacher.

    Please note:

    • Any documentation submitted for verification purposes will be used solely to confirm your status as an active teacher. We will not use your verification documents for any other purpose. All documentation must be sent to verify@skewthescript.org

    • While we’re not currently able to verify homeschool teachers, we’re happy to review requests on a case-by-case basis. Please send any relevant documentation to verify@skewthescript.org.

    Once your documentation has been reviewed and approved, you will receive a confirmation email granting you full access to verified teacher resources. Verification is typically completed within 3-5 business days.
