If you have ever wondered whether parents pushing, cajoling, helping and generally being on the case is worth it then I have some good news for you! Research shows that one of the greatest determining factors in academic success is parental involvement. A variety of reports from credible sources such as the BBC indicate that children who get As or Bs in school do so because of encouragement at home.
When surveyed up to 90% of the children with high grades say they are encouraged to do well by their parents, on the other hand 40% of children who get Cs or lower report that they are not encouraged. Clearly where statistics are involved it's useful to be a little wary but most people who do well academically can point to a relative (if not a parent) who was encouraging.
