Regarding attrition, do you trust any data on dropout rates in the US? When I started to look at this in the past, I was frustrated to learn of the different ways that schools and districts can define "dropout". There's under-accounting, where students who leave before a certain grade level or age are not taken into account. There's over-accounting, where students who take longer than four years to graduate are counted as dropouts. Given that, I've ignored most data I've seen about dropout rates. Do you have any perspective on this? PS I always appreciate your comments on education. Thanks for continuing to offer your perspective, even though these articles often get killed.
