Think I'll add this is a general one. NCLB or Title II or whatever defines a "highly qualified teacher" as someone who

1. Has a Bachelor's degree (doesn't have to be subject-specific)
2. Has certification from the state
3. Has passed a test in the area s/he teaches.

Personally, I would see these requirements as describing a bare minimum, not grounds for being labelled "highly qualified." But that is just me.
