sorry Anon…not true.
I did it…K-5 through Highschool.
Taught my 2 kids EXACTLY what I wanted them to learn…TRUTH…unadulterated.
They can think critically and are not inlfluenced by peer garbage.
They took the SAT's, did fine, both have college degrees and jobs.
Colleg degrees are STEM.
Only thing I can say is that each state is different - some require yearly standardized testing, some do not. Our state does not. I did the testing anyways…they tested off the charts.
It can be done - (((BEST thing I ever did with my life.)))
