Hybrid "Teachministrators"

Having administrators who remain part-time classroom teachers should be the norm, not the exception.

I will concede that some administrators are good at their jobs, but not meant to be in the classroom. But with so many top-down instructional mandates from Central Offices to Principals to Teachers, it makes more sense to have those demanding results and changes try to do it themselves too have a better understanding of what works and what doesn't. To stay abreast of what it's like to be in the classroom, what the students are really like, etc., can't hurt either.

Some administrators are so far removed from teaching. Is this right? Would schools be better off with a couple more administrators, each of whom still maintains an active role in the classroom?
