I guarantee you (and the data backs this up) that the home schooled religious kids that are taught the earth is 6,000 years old and were spanked can run circles academically around the average public school kid.
The data has been posted elsewhere in this post but here is some more below [0]. Why do you assume religious homeschoolers would perform worse than non-religious homeschoolers? Thanks for downvote :)
[0] 78% of peer-reviewed studies on academic achievement show homeschool students perform statistically significantly better than those in institutional schools (Ray, 2017). Source and lots of other good tidbits: https://www.nheri.org/research-facts-on-homeschooling/#:~:te....)
I’m not sure why you would even distinguish religious home schoolers from non religious. Some quick googling shows that 90% of home school parents are religious which would back up my claim. I’m sorry you hate religious people?
