grade. In reality, A. R. is definitely
feeble-minded. Although she is from a home of average culture,
is 11 years old, and has attended school five years, she has
barely the intelligence of the average child of six years.

_D. C. Boy, age 17; in fifth grade._ His teacher knew that he
was dull, but had not thought of him as belonging to the class
of feeble-minded. She had judged this boy by the 11-year
standard and had perhaps been further misled by his normal
appearance and exceptionally satisfactory behavior. The Binet
test quickly showed that he had a mental level of approximately
9 years. There is little probability that his comprehension will
ever surpass that of the average 10-year-old.

_R. A. Boy, age 17; mental age 11; sixth grade; school work
"nearly average"; teacher's estimate of intelligence "average."_
Test plainly shows this child to be a high-grade moron, or
border-liner at best. Had attended school regularly 11 years and
had made 6 grades. Teacher had compared child with his
12-year-old classmates.

_H. A. Boy, age 14; mental age 9-6; low fourth grade; school
work "inferior"; teacher's estimate of intelligence "average."_
The teacher blamed the inferior quality of school work to "bad
home environment." As a matter of fact, the boy's father is
feeble-minded and the normality of the mother is questionable.
An older brother is in a reform school. We are perfectly safe in
predicting that this boy will not complete the eighth grade even
if he attends school till he is 21 years of age.

_F. I. Boy, age 12-11; mental age 9-4; third grade; school work
"average"; teacher's estimate of intelligence "average"; social
environment "average"; health good and attendance regular._
Intelligence and school success are what we should expect of an
average 9-year-old.

_D. A. Boy, age 12; mental age 9-2; third grade; school work
"inferior"; teacher's estimate of intelligence "average."_
Teacher imputes inferior school work to "absence from school and
lack of interest in books"; we have yet to find a child with a
mental age 25 per cent below chronological age who _was_
particularly interested in books or enthusiastic about school.

_C. U. Girl, age 10; mental age 7-8; second grade; school work
"average"; teacher's estimate of intelligence "average."_
Teacher blames
