Melissa Sundqvist's Profile

If two average 8-year-olds are assigned to different teachers, one who is strong and one who is weak, the children's lives can diverge in just a few years, according to research pioneered by Eric Hanushek at Stanford. The child with the effective teacher, the kind who ranks among the top 15% of all teachers, will be scoring well above grade level on standardized tests by the time she is 11. The other child will be a year and a half below grade level--and by then it will take a teacher who works with the child after school and on weekends to undo the compounded damage. In other words, the child will probably never catch up.
