Just cruising around and ran across this over at Breitbart:
In a study published in 2009, 12,000 homeschooled students from across the 50 states were tested on national measures of reading, language, math, science, and social studies. In the core studies of reading, language, and math, the average homeschooler scored at the 88th percentile, while the average public school student taking the same standardized tests scored at the 50th percentile.
It also points out that they are generally more socialized to boot. The post is about the rise of homeschooling and some of the “over the horizon” threats that could restrict that growth; if you have a few minutes, it’s a good read.
