A reader offers this observation:

“Before teaching, I worked in software development. If our company released a major product revision with no quality assurance testing and no trial beta release, we would be out of business in a week as well as the laughing stock of the industry.

“Common Core is a corporate initiative written from ivory towers. Teachers had little say. The standards are poorly written and suppress innovation and learning. We have no idea if they are effective or relevant. The logo for Common Core should be a picture of lemmings going over a cliff.”
