An analysis of 20 years’ worth of school suspension rates nationwide shows that the greatest influence on boys’ behavior at school is not the type of school they attend or teacher they have, but the type of home in which they’re being raised. Researchers at the University of Chicago Booth School of Business found that boys being raised in intact homes with both parents had the least behavioral problems and school suspensions, while those being raised by single mothers had the most. However, this was not found to be the case among girls. (WNS)
