Teacher attrition is a problem with a number of implications, not the least of which is the teacher shortage. Almost half of all new teachers leave the profession within the first five years, creating a difficult model where more teachers leave the teaching profession compared to teachers entering the profession. Part of the problem is a result of career progression. However, most of teacher attrition is a result of factors such as inadequate pay, administrative support, workplace conditions, student related issues, and collegiality with peers. Without a thorough understanding of the factors that contribute to teacher attrition it is impossible to create an environment where "No Child is Left Behind". Although teachers do not enter the profession with the notion of getting rich, they do need to make enough money to support themselves and their families. Furthermore, professional status in America is closely tied to socioeconomic status. Therefore, while salary may be the largest component of teacher attrition, school and district characteristics, teacher qualifications, and demographics also affect a teacher's decision to leave the profession.
