As a school admin, you can re-publish a post in your name. Go to the post's three-dot menu and select Repost to Feed.
The system opens a post-creation interface where you see the post text. You can edit the text if you want.
You can copy over the post's photos, attachments, and video. To copy over this content, simply check the checkbox (checked by default).
Click Share.
Note: The repost is made in your name even if the original post was posted by another user.
