involves placing children in a certain group based on their perceived ability
each ability group is then taught separately form the others for all subjects
studies show that the self-fulfilling prophecy is particularly likely to occur when children are streamed
working class children are more likely to put themselves in a lower stream
once streamed it is usually difficult to move up to a higher stream; children are more or less locked into their teachers low expectations of them
children in the lower streams 'get the message' that their teachers have written them off as no-hopers
Douglas found that children placed in lower streams at young ages suffered a decline in their IQ score as they grew older
by contrast middle class pupils tend to benefit from streaming as likely to be placed in higher streams reflecting teachers view of them as the 'ideal pupil'
