Child support, in brief?

PTA

Think of a group that often organizes school events and fundraisers, commonly made up of parents and teachers. The initials might sound like a test you take in school.

Child support, in brief?" plays on the double meaning of "child support." While it usually refers to financial payments for a child’s care, here it hints at an organization that supports children—specifically the Parent-Teacher Association, commonly shortened to PTA. The "in brief" signals the answer is an abbreviation, making PTA the perfect fit.
