Oo I wrote a lovely long post about this and the page crashed! Grr.
I moved from mainstream English teaching when it became too admin focused (and I experienced the awful culture described by many above), to alternative provision where the remit was about using creative approaches to re-engage the most vulnerable and disaffected students in learning.
However, the government removed the specialist PRU Ofsted criteria, and made all PRUs be inspected on the same criteria as mainstream schools. In short, the focus changed to academic, the pressure ramped up on staff through performance related pay, and the most vulnerable youngsters are voting with their feet. The freedom and joy of using creative approaches to engage has been lost.
I initially left my post to bring up DS, as I was told I couldn't do my management role part time, and wasn't prepared to be demoted and see someone else fuck up do my job. It has changed massively now anyway, and the beautiful creative ethos and pastoral focus has been destroyed by the excessive focus on data, evidence, and bloody progress. When success looks like a young person actually turning up and staying in the classroom for an hour, and the criteria want you to write which level they are working at, what do you do?! If they are making academic progress they go back to school ffs. I have never seen morale so low as I have amongst my former colleagues, who all left mainstream for the same reasons as me - too much focus data and bad workplace culture.
So I wouldn't go back, however I have to do something as we need the cash so have signed up with a teaching agency for sept somebody stop me. I am sad that I can't currently use my specialisms and help vulnerable youngsters, but government policy has destroyed what it was. If you make the inspection criteria impossible to meet, it makes enforced academisation much easier you know!
