Earlier quoted context omitted.

Are you a better programmer now than you were 5 years ago? How do you know? Has anyone evaluated your work and told you are now 18% more efficient than 5 years ago? It may not be 100% accurate (since we are all masters at deluding ourselves), however it is possible to self-assess. Speaking as a teacher I know that my work is much better than it was 7 years ago (when I started). Simply delivering the material so many…

In companies of any size, programmers generally go through quarterly, biannual, or annual performance reviews where they are assessed by the manager and peers. Programmers who are overperforming are promoted and given more responsibility (and money), those who are under-performing get coaching or are fired. This is the same as virtually every other job on the planet. You can argue this kind of evaluation is not fair…

Forgive if someone has already stated the obvious, but the difficulty of rating the teacher profession, as opposed to other professions, lies in the intended outcome. For an engineer, there are many objectives metrics to measure code work against. The same is true for many non-programming corporate jobs (usual metric is $$$).

But what is the intended outcome of teaching?

Better test scores? (Google Scholar 'standardized testing and success' and take your side of the argument, but at best the jury is still out)

The three R's? Social development? Curiosity for learning? All of the above?

I understand your underlying point, but it is dangerous to contrasts teacher evaluations with other professional evaluations, lest we find ourselves programming students a science) and not teaching them (an art).

Crazy idea alert! With intended outcomes varying so much for teachers and teaching environments, I'd offer that teachers should be only evaluated by fellow teachers, parents, and students themselves.

The blog post author is a provider of educational software sold to schools, writing to identify problems that he thinks arise from the Khan Academy approach to online education. I'll respond to what he said now that I've read the blog and the earlier thoughtful comments on his blog and here on HN. 1. It is hard to compete against free, especially in education. Adam Smith pointed this out a long time ago: "In modern t…

ALEKS is awesome, I used it 10 years ago to refresh on some math topics. I should try it again just to see how much has improved since then.
