Heads will have to ensure that assistants are directed and supervised by qualified teachers, and that every class or group is assigned to a qualified teacher who will remain responsible for pupil progress.
David Miliband, school standards minister, said more support staff were key to reducing teachers' workload. But he insisted they were not a replacement for teachers, as some fear. "No one suggests nurses should do brain surgery. But no brain surgeon would work without a nursing team. These proposals are about giving teachers the professional support to do their jobs to the highest standards."
The new standards for assistants say, for example, that they must be able to "work collaboratively with colleagues as part of a professional team".
But, while teachers are expected to "know and understand" curricula, teaching methods and expectations for their subjects and age groups, senior assistants need only be "aware" of these.
The Teacher Training Agency pilots training for senior assistants this autumn. Around 7,000 are expected to train in 200304, rising to 20,000 a year. Courses are expected to last around 50 days.
