Huffman is accused of paying $15,000 — disguised as a charitable donation — to the Key Worldwide Foundation so her oldest daughter could participate in the scam. A confidential informant told investigators that he advised Huffman that he could arrange for a third party to correct her daughter’s answers on the SAT after she took it. She ended up scoring a 1420 — 400 points higher than she had gotten on a PSAT taken a year earlier, according to court documents.
The 1020 her daughter got was just about exactly the PSAT average.

The 1420 cheating score was well over the 90th percentile.
