In New Jersey you have to pass a Praxis exam to get your teaching degree. It is a proficiency test in your major, like Social Studies or Language arts, etc. THAT is what they need to publish.
But the Praxis is not much of a test, and last time I checked only 29 states used it . Moreover, the passing level is set by each state. As a result the passing scores selected by the states are quite low. In fact, not long ago only Virginia required teachers to be able to read at or above the national average. In DC and Florida, for example, you could take the Praxis and score below the 25th percentile in reading and still be hired as a highly trained education professional.
Praxis is a joke. I took it in MD.
