Teacher aides - who benefits most, teacher or student?

Has a rise in the number of teacher aides in classrooms around the country been matched by a rise in achievement among those students?

The Education Ministry here is issuing guidelines to schools on how to get the best out assistant teachers - and by the end of the year says it will have a system in place to measure student achievement.
