Some teachers don't have to do that.

One reason we sent our daughters to (private) Montessori school was to have teachers and lessons completely free from Common Core.

Note that Bill Gates also sent his children to a private school that never adopted Common Core, although he was instrumental in pushing and forcing Common Core requirements across the public schools of the country.

Common core standards for English and math were released 2012 with adoption spread out across years for many states. Development of the standards started in 2009. Gate's youngest child would have been starting school ~2008.

Actually the release date was 2010 not 2012: "Standards were released for mathematics and English language arts on June 2, 2010, with a majority of states adopting the standards in the subsequent months." [1] It was adopted by Washington State in 2011. [2]

Are you implying that his children were subjected to Common Core, or that they couldn't have? by 2011, they were age 9, 12, and 15.
