Reality Check - Series 3 - School testing

Justin Rowlatt returns with a series of debates on topical issues, bringing together experts in a particular field with people living at the sharp end. He visits a primary school in South London to ask whether testing young children really helps them, or whether it subjects them to unnecessary stress. And is the point of SATS tests to benefit the children themselves or to give an indicator of school performance? Producer: Adele Armstrong.
