Roachian Education is typically rather low. Most children are home-schooled by parents who themselves don't really know what they're talking about, or have no education whatsoever. Very few schools exist, and they are generally private (such as the St Elvis Presley Boarding School (Education/St Elvis Presley Boarding School)) and cost too much to get into. Typically, what is known by all citizens is the relationship the gods and man... And survival.
