When I first discovered Classical Education, I was very excited and intrigued with it. After reading a lot about it, and coming to understand how my children are best educated, I would discourage others from using this method rigidly. Everyone wants their children to excel, and be the best they can be, but I just do not agree that it is good to fill a young child's mind with facts upon facts that they then learn to tie together as they age. This method is too harsh for young children, and just ends up recreating school at home if homeschooling, or pushes kids to do more than they are able if in school. It focuses on workbooks, and lots and lots of memorisation. It is very rigid, with a set formula for each grade (age). The Well Trained Mind is the book to read if you want to learn about it.
That said, classics (which is not just limited to books, a classic can be anything that you come back to over and over) are great teachers, and they should be used as the main source of education. Classical Education is not about classics though. It is the form of education that was supposed to have been used in the classical past, using the trivium as its foundation.
