Die Qualität des Lehrkörpers beeinflusst – offensichtlich auch statistisch nachweisbar – das Lebenseinkommen der Schüler. Lesen Sie selbst:
Over the course of just one year of teaching, a teacher who is at the 60th percentile in effectiveness (better than 60% of others) raises students‘ lifetime earnings by an average of $5,292 per person, which translates into a present value of $105,830 for a class of 20, says Eric A. Hanusheka of Stanford. Below-average teachers produce corresponding decreases in earnings, so gains will be canceled out if a student gets a bad teacher after having a good one, Hanusheka says.
