Educators in recent months have sounded the alarm about a troubling trend nationwide: more preschoolers getting expelled and suspended. According to the U.S. Department of Health and Human Services, the expulsion and suspension rate is three times more for preschoolers than children in kindergarten through 12th grades. Dr. Tim Zeng, with the Early Education Leaders Institute, presented his research Thursday in Minnesota, revealing 49% of pre-school teachers said they suspended a student in the past year.
