Dividing children by “Grade Level” is convenient and seemingly necessary for large schools that can only afford one teacher per 20+ students, but it is harmful to the healthy development of our children. Skills and maturity are the two major categories of development that measurable and students do best when with others who are at similar levels. Expecting any number of children to be at the exact same skill level and maturity level is.. well, delusional. That is not the goal, but having a reasonable range of skills/maturity allows for children to develop a sense of self awareness and personal motivation. Personalized learning experiences with peers and the opportunity for progressing through levels at a more natural page takes the factory elements out of education and encourages the beauty of our human gifts to develop.
