Reducing student expelsion study

Support teachers, reduce class sizes to lessen preschool expulsion
To help reduce the number of children expelled from early-childhood programs, their teachers need more support and fewer students, Yale University researcher Walter S. Gilliam says in a new study. Reducing student-teacher ratios to 10 or fewer, offering preschool teachers more frequent breaks and giving them access to tips from mental-health experts will help improve student behavior and keep more in class.
