One of the reasons I like the Eduwonk blog so much is that Andy Rotherham doesn't pull any punches. I may not always agree with what he says, but he dares to speak his mind. For example, in a recent post he says that K-12 education

'is a culture that accepts and institutionalizes [teacher] mediocrity'

and that there is a

'chronic lack of emphasis on effectiveness and performance at every step along a teacher's value chain from preparation, recruitment, hiring, induction, mentoring and support, and professional development to evaluation and compensation.'

He goes on to say that

'talented people don't want to work in places that aren't talent sensitive and this creates an adverse selection problem that reinforces these problems. [Also,] current practices make this even worse in practice ... and credentialing rules, which often have little connection to research, further limit the pool of would be or could be teachers.'

Andy's original post is here and includes some interesting links to other sources. What do you think of Andy's comments? Is he off-base or right on the money?
