PARENTS are alarmed that children at a primary school in Melbourne's east began wetting themselves after the school tested an approach that discouraged them from going to the toilet in class time.

In the Kew Primary School trial, which parents said was conducted without their knowledge, the entire class would go to the toilet if one child needed to go during a lesson.

One mother, who asked not to be named, said she first became aware of the trial when her child wet herself at the front door. ''I said, 'What happened? She said, 'I'm holding on, I didn't want the whole class to have to come with me to the toilet.' At first when she told me the rule I disbelieved her.''

Another mother took her high-achieving child to the doctor after she wet herself twice at home.
