But a Canadian couple has just won a legal battle to 1 their offspring from homework after successfully arguing there is no clear evidence it improves academic performance. Shelli and Tom Milley, two lawyers from Calgary, Alberta, launched their highly 2 case after years of struggling to make their three 3 children do school work out of the classroom. After waging a long war with their eldest son over his homework, they decided to do things 4 with their youngest two. And being lawyers, they decided to make it official. It took two years to 5 the Milleys' Differentiated Homework Plan, which 6 their youngest two children will never have to do homework again at their current school. The two-page plan, signed by the children, parents and teachers, states that "homework will not be used as a form of evaluation for the children". 7, the pupils promise to get their work done in class, to come to school prepared, and to revise for tests. Two years ago, Shelli began collecting studies on homework, most of which suggest that, 8 for younger grades, there is no clear link between work at home and school performance. Working with the staff at St Brigid Elementary/Junior High School, she formed a homework committee. When no firm changes 9 from the committee, the couple began negotiating the legal document that decided the matter. "We think it's a parent's 10 to choose what's in our children's best interests," said Shelli. "But we're thankful the school did the right thing."
