Have you ever noticed the little blue / grey tick next to certain social media accounts (usually celebrities or brands)? They mean that these accounts have been verified; they are the authentic account of that person / entity.
Most social media channels now have a verification process. For schools, some are easily obtainable and some are more difficult to get - each channel has their own prerequisites for verification.
Facebook and YouTube are two of the simplest, taking no more, generally, than 10 minutes to obtain each one. We highly recommend that every school verifies both Facebook and YouTube, as there are benefits in doing so.
