Character as it relates to character education most often refers to how 'good' a person is. In other words, a person who exhibits personal qualities like those a society considers desirable might be considered to have good character—and developing such personal qualities is often seen as a purpose of education. However, the various proponents of character education are far from agreement as to what "good" is, or what qualities are desirable. Compounding this problem is that there is no scientific definition of character. Because such a concept blends personality and behavioral components, scientists have long since abandoned use of the term "character" and, instead, use the term "psychological motivators" to measure the behavioral predispositions of individuals. With no clinically defined meaning, there is virtually no way to measure if an individual has a deficit of character, or if a school program can improve it.
