I’d hope there are.

Rather like with politics, a desire to only be a teacher without actually building on one’s experiences and character surely must result in a pretty poor final product. I believe that there should be some significant substance to the teaching staff as a group, beyond just being qualified. Newly qualified learning from more experienced colleagues. Knowledge passed down. Every day being a learning day, for everybody.
Being able to cite ad nauseum a curriculum which has been established elsewhere is all well and good, but if there is little appreciation of how the imparted knowledge might benefit the student, how can a student be answered when they ask ‘So what?’

I’ve experienced this locally with arrogant and very young teachers who have ‘made the grade’ and therefore have nothing more to learn, and as a consequence have little respect for their students, the parents or their more experienced colleagues. Likewise, I’ve flown with younger and older colleagues with the same mindset. They fail to appreciate that their viewpoint is only relevant in their little bubbleverse. They’ll be safe so long as it lasts, but if the bubble bursts, and they have to find their way in a different, more exacting arena, they’ll likely be found wanting.

The deadwood who have been hanging on for years will no doubt still hang on. The greater loss is that experience and knowledge that may no longer exist with the departure of older hands. Having an arbitrary retirement age, rather than retirement based on competency achieves just that.

(I’m likely just rambling)
