I would love if the percent completion of lessons can be visualized by subject area so parents can easily see where their child is and how they are progressing along the Montessori continuum. Bonus if they can see where the child is in reference to their class curriculum (i.e. how much of the lower elementary language curriculum they've mastered), and look at the entire scope (where they are in reference to graduation or the highest level offered at the school). I envision a circle chart or a progression bar to visually represent each subject. Parents can then see an instant overview of their child's progression by accessing their child's page at any time. Clicking on the progression bar should lead them to the full list of lessons/standards/skills associated with their child's environment.
