Please note: Our assessment resources are not official guidelines. They are based upon our own ideas, taking into account the APP and Primary Framework documents for mathematics, about what a child working at a particular sub-level should be able to achieve. They are provided simply as an assessment aid so feel free to use them as strictly or loosely as you wish. However, we recommend that a child should be able to achieve at least all but two or three of the given criteria in a sub-level before they can be judged to have reached it.
