The most common use case is when someone would like to authorize his / her child’s school to release your child to another individual. And a parent would like to give authorization for another individual to make decisions regarding your child in your unexpected absence. This agreement allows someone to temporarily care for or make decisions about your kid, such as allowing a relative to pick up your child from daycare. If you want to grant legal authority to make major decisions, create a POA for child instead. This document is also sometimes called a CCA form or CCA letter.
