The Civil Rights Project at the University of California Los Angeles found that suspensions cost America almost $36 billion dollars for the graduating class of 2004 (1). Suspensions have a longterm affect on many who students who are suspended — it has been found that kids who are suspended even one time are more likely to drop out of high school.
To come up to that $36 billion figure, researchers took into account the fact that students who drop out of high school are generally less healthy, more likely to use welfare, and earn less/pay less in taxes. They then compared analysis of those costs to society to the number of students who were suspended and then dropped out of high school.
In addition to this exorbitant cost of school suspensions, it has been found that states spend $5.7 billion per year on placing youth in juvenile justice facilities (2).
While it is very difficult to determine the exact longterm financial cost of not providing trauma informed care, it has been found that child abuse costs the United States $220 million every day. Providing training and implementing trauma informed care may incur costs, however, they are certainly more morally and financially cost effective than allowing ACEs to affect children without intervention.
