Over 100 Catholic educators sent each US bishop a copy of their joint letter decrying Common Core and detailing why Common Core is a danger to authentic education. They reiterate that Common Core is not about true education of human beings but about training future workers, or (in my own words) programming little robots to obediently take their pre-assigned places in the workings of the socialist utopian-state "people's paradise".
I link the letter now. It is a pdf file so it is downloadable. Remember - this letter was penned and/or signed by Catholic educators who have been exercising that apostolate for decades. I hope this can be broached by the bishops at their Baltimore meeting in a few weeks.
