Should children be tested at primary school?

An interesting survey for New Zealand parents on "Should children be tested at primary school?" Look at the responses from parents, at a glance, they are all in favor of the tests.

We think that the idea of conducting tests to measure against own’s past results is better than against your peers’.  This creates nothing but unnecessary pressure on the children. What do you think? Do you think we should put pressure on our kids from such a young age?
