In Classio, when an administrator or other authorized user creates an account, the person receives an invitation email for setting a password. Once they set a password from the link in the email, they can start using Classio. Invitations are valid for 7 days.

Invitations (招待管理) is the screen for checking and resending invitations that have been sent but not yet used and have not expired. You can also send invitations from here to people who have an account but have not yet received an invitation. It is available to administrators and academic administrators, and is shown on the Standard plan and above. Academic administrators can handle invitations for teachers, students and guardians.

School invitation and cohort links open at the school address. Schools with an active custom domain receive links at that address. Nobica learner invitations open on Nobica.

  1. Register teachers one at a time from Add staff member (職員を追加) in the Staff directory (職員一覧). If you press Add (追加する) with Send invitation email (招待メールを送信する) left on, an invitation email is sent. If you turned it off, you can send it later from Accounts waiting for activation (有効化待ちのアカウント) in Invitations.

  2. To register several people at once, open Invite teachers in bulk (教員を一括招待) in Invitations, or Staff bulk registration (職員一括登録) in the menu. Fill in the Excel template, upload it, check the contents and register; invitation emails are sent to the registered staff.

The link in the invitation email opens a screen for setting a password. If the school has already registered the person (for example, they are in the Staff directory or the student list), they only check their email address (and their name, when the school has registered one) and choose a password. A name and phone number are asked for only from people who are newly registering as a teacher or guardian.

  1. Open Invitations (招待管理).

  2. If needed, choose a role in Filter by role (ロールで絞り込み).

  3. In the list, check the email address, role, name, created date and time, and expiry. Invitations with less than 2 days until expiry show Expiring soon (まもなく期限切れ).

  4. To revoke an invitation sent by mistake, press the delete icon (Revoke invitation (招待を取り消す)) at the right end of the row, and confirm.

Resend an invitation when someone says the invitation email did not arrive or they cannot find it, or when the registration screen shows "The invitation email could not be sent" (招待メールを送信できませんでした).

  1. Open Invitations (招待管理).

  2. Find the person's row in the list and press Resend (再送).

  3. When "Invitation resent" (招待を再送しました) appears, you are done. The new link is valid for 7 days from when you resent it.

Resending sends a new link, and the link in the earlier email stops working. Tell the person to use the link in the most recent email.

Accounts waiting for activation (有効化待ちのアカウント) shows people who have an account but no usable invitation. This happens when staff were registered without sending an invitation, or when an invitation expired or was revoked.

  1. Find the person in Accounts waiting for activation in Invitations.

  2. Press Send invitation (招待を送信).

  3. Once sent, the person moves to the Pending invitations (保留中の招待) list.

With Create cohort invitation URL (コホート招待URLを作成) at the bottom of Invitations, you can create an invitation URL for a specified department and year. When a student opens this URL, an application form with the department and year already filled in appears. Share the URL you create with students.

Pending invitations shows only invitations that are unused and have not expired. Invitations for which the person has set a password are not shown. Accounts whose invitation has expired are shown in Accounts waiting for activation. Recruiters awaiting approval are handled in Recruiter requests (採用担当者申請), not here.
