International Perspective
Across countries there are wide differences in the use of formal tracking systems. Even though some countries track students into differing-ability schools by age 10, others such as the United States keep their entire secondary-school system comprehensive. Eric Hanushek and Ludger Woessmann identify the impact of tracking by comparing differences in student outcome between primary and secondary school across tracked and non-tracked systems. The results suggest that early tracking increases educational inequality. While less clear, there is also a tendency for early tracking to reduce mean performance.

Famous quotes containing the word perspective:
“A lustreless protrusive eye
Stares from the protozoic slime
At a perspective of Canaletto.
The smoky candle end of time
Declines.”
