i work in a complex environment where there's performance related pay - i'm sure many people do in the private sector. If targets can be set and monitored for what i do I don't see why they can't for teachers.
So would you be happy for your pay to be based on what others around you did, not what you did?
Oh and no selection criteria and no way to fire anyone not pulling their weight, you have the team you are lumped with?
So someone comes in with a drug problem and unable to write, falls asleep at their desk and then does not appear for 2 weeks and your pay is based on their performance?
And you can't say, "well the other 25 all did very well" because your pay is based on the performance of the entire group.
That is how performance related pay would work for teachers.
I taught a girl who arrived in the UK aged 14 with no English (I didn't teach her until she was 16), she passed 10 GCSEs A-C (no A8 at the time) the one GCSE she had a D grade in was English Language. That means that by all current measures she gave the school no 'points', the school had failed her.
Let me repeat, in 2 years a school had managed to get a student from knowing no English to 10 GCSEs yet was marked as a failure. Would you accept that in industry?
