Jose O. Montano, a 17-year-old ninth grader from El Salvador, and Henry E. Sanchez-Milian, an 18-year-old ninth grader from Guatemala
So they were 4-5 years older than a typical 9th-grader. I bet their real intellectual level was in lower grammar school range, but School District couldn't put them there.
We only have their word. They could be in their 20s - no papers you see.
