This is absolutely not true. For example, a PhD is marine biology says nothing about your ability to teach differential equations. And it is amazingly common, from my experience interviewing candidates for community college jobs, for people with graduate degrees to be utterly incompetent in the subject in which they have a graduate degree. We have had people with a PhD in physics who couldn't apply Gauss's law to find the field of a point charge, and people with a master's in math education who couldn't differentiate sin(cos(tan x))..
Just now getting back to this thread guys! Thanks to everyone for your responses!
For what it's worth, my community college has some math instructors who are incompetent in class material they are not assigned to teach. For example, when I took pre-calculus last year, one of my instructors explained to the class that she wasn't going to be teaching any applied or "regular" calculus (w/ analytic geometry) courses in the Fall and that she might need to brush up on the material if the department ever asked her to. She was a "lower" ranking instructor (I believe a part-time lecturer) and mostly taught pre-calculus and below. I saw that her credentials showed a Master's degree in mathematics, but perhaps it was a long time ago and she had gotten rusty on some topics. She happens to also work in our school's "math lab" (a free tutoring center offered to anyone enrolled in math) and frequently declines questions from students in calculus and differential equations. I've seen her tell students that they would have to ask someone else for assistance on those topics.
Similarly, my second semester pre-calculus teacher last year frequently had to stop to redo problems and think for what seemed an inordinate amount of time before solving certain homework or book example problems. She frequently made mistakes or got "lost" in her train of mathematical thought. It felt like she was not that good at the subject! Students would talk behind her back and complain about her competence. She was a very friendly and caring teacher, nonetheless. She just didn't seem like the most proficient and effective instructor on the subject.
My applied calculus teacher, however, is quite good this semester. He's able to explain things well and knows his stuff. And he challenges the class to learn beyond rote memorization. My community college math instructors have been a sort of mixed bag in terms of competence - both in terms of teaching acumen and mathematical knowledge.
High school felt the same way. I recall teachers of one level of math having to ask the 12th Grade math teachers how to do something before.
Is it just unreasonable to expect a math instructor to recall and have mastery over all of their course work in graduate school years after finishing their degree and having not used some of the material afterwards? There's the saying, "use it or lose it," and I wonder if these instructors are just naturally losing their competence over time from inactivity and use of the material?

A few years ago, my wife went back to school to get a teaching credential so she could transition from computer programming to teaching high school math. I think it bears repeating that in all of her job interviews after obtaining her credential, she was never asked a single question about math. Not one...
What types of questions did they ask her, out of curiosity?

Recent Ph,D's are also competing with Masters graduates for community college positions.
How do the Ph.D.s fare against the Master's students? I know bcrowell said it can depend on the dynamics of a school as to possibly favoring one over the other, but generally speaking are the Ph.D.s simply better off/more competitive, due to the higher level educational credential?
Or, conversely, might they be "overqualified" in some way?
