There is considerable overlap between tasks teachers must do to be an excellent teacher and those required of staff who get paid management allowances, said the National Union of Teachers.
But other unions - who unlike the NUT are involved in social partnership with the Government - welcomed three new sets of draft standards. These outline respectively what teachers must do to be promoted to be excellent teachers, advanced skills teachers (who are expected to work in a number of schools), and to cross the threshold to the upper pay spine.
They said the proposals offered teachers who had reached the top of the upper pay scale a choice of career routes while giving schools the ability to create pay structures that fit their needs.
The excellent teacher scheme will be introduced in September with salaries of pound;35,874 across England and Wales, rising to almost pound;43,000 in inner London.
Teachers now at UPS3 will be eligible for the grade, which was promised after the Government shortened the upper pay scale.
Excellent teachers will be expected to take a leading role in developing school improvement policies and use research evidence to inform teaching of colleagues -both of these duties can also attract teaching and learning responsibility payments.
From September, teachers outside London at the top of the main pay scale could earn up to pound;44,000 through a combination of their pound;33,000 salary and a teaching and learning responsibility payment of between pound;2,300 and pound;11,275.
Steve Sinnott, NUT general secretary, warned that the Government has no way of monitoring whether the new pay structure will be fair to different groups of teachers including women and ethnic groups.
He said: "It will lead to massive practical differences from school to school. Unless they put a proper appeals process in place, headteachers will be open to accusations of acting unfairly, often through no fault of their own."
But the unions which helped draft the standard said they added to career options for senior teachers. John Dunford, Association of School and College Leaders' general secretary, said they could choose between becoming an excellent teacher, advanced skills teacher, joining the leadership team or taking on a teaching and learning responsibility.
He said: "If you are an excellent teacher you won't get a TLR. You can't have both, but in becoming one you will take on other responsibilities.
"What you have got is a national framework with local flexibility. That's what unions wanted and it is up to schools to use the flexibility to fit their own circumstances."
The Government has watered down requirements for teachers to show their teaching leads to higher standards for pupils before they can cross the threshold. In future, teachers will merely have to show that they "have teaching skills which lead to learners achieving well" compared to similar pupils elsewhere.
