A teachers union punch line to cover for progressive teaching.
"Teaching to the test" is what teachers call being distracted from teaching the crap they normally teach. Quoted from a former teachers union rep I know.
If our kids got the kind of well rounded education my generation received back in the 1970s and 1980s the teachers would not need to "teach to the test" because kids would already be armed with the basic skills needed to pass the standard tests.
Every kid I graduated with had basic STEM skills competency that most of todays high school graduates lack. I find it amusing that another post on this site discusses the importance of the English language in the global market place, yet far too many high school graduates in several major US cities including LA, Chicago and even Washington DC. have no better than a 10th grade reading level when they graduate.
Instead of teaching the basics we have high school seniors spend an entire semester on the history of black culture in TV and movies ( a great college course I took by the way), or the outrageous Mexican studies classes popular in Southern California and Arizona that are offered only to people of Mexican descent. Something already found to be illegal by more than one court.
Those are the classes where they teach a fictional history of how the American army enslaved the Mexican people for decades and stole half their country when they finally left. Teachers in these classes openly promote a violent Mexican led rebellion in those states to be inevitable.
