Test: At least 20% of children learning to read independently via their own computer before grade school: no evidence of more than a small share in 2009 or 2014.
Grader B: miss
There is no evidence that many children taught themselves to read on PCs before school; early literacy software was supplementary.
Test: Share test: self-taught reading via PC well below 5% of children.
