A Bratayley fan quiz is a quiz testing one's knowledge of the popular family video logging channel, Bratayley, which is available to watch on YouTube. It follows the daily life of three siblings: Caleb, Hayley and Annie.
The quizzes ask detailed questions, such as, "What is Annie's real name?" and "What sport does Caleb do?" There is also a quiz in which one can determine which Bratayley character one is most like.
The Bratayley channel was originally created solely for the youngest of the three, Hayley. They came up with the name by combining her name with "brat." Their parents later decided to devote this channel to the entire family. Each of the children is active on the YouTube channel OMMYgoshTV, and Annie and Caleb have their own solo channels. Their parents are Katie and Billy.
