The Relation Of The I Q To The Quality Of The Child's School Work
The school work of 504 children was graded by the teachers on a scale of
five grades: _very inferior_, _inferior_, _average_, _superior_, and
_very superior_. When this grouping was compared with that made on the
basis of I Q, fairly close agreement was found. However, in about one
case out of ten there was rather serious disagreement; a child, for
example, would be rated as doing _average_ school work when his I Q
wou
When the data were searched for explanations of such disagreements it
was found that most of them were plainly due to the failure of teachers
to take into account the age of the child when grading the quality of
his school work. When allowance was made for this tendency there
were no disagreements which justified any serious suspicion as to the
accuracy of the intelligence scale. Minor disagreements may, of course,
be disregarded, since the quality of school work depends in part on
other factors than intelligence, such as industry, health, regularity of
attendance, quality of instruction, etc.

Some Avowed Limitations Of The Binet Tests
The Binet tests have often been criticized for their unfitness to perform certain services which in reality they were never meant to render. This is unfair. We cannot make a just evaluation of the scale without bearing in mind its avowed limitations... Sources Of Data
Our revision is the result of several years of work, and involved the examination of approximately 2300 subjects, including 1700 normal children, 200 defective and superior children, and more than 400 adults. Tests of 400 of the 1700 normal child... Special Characteristics Of The Binet-simon Method
Psychologists had experimented with intelligence tests for at least twenty years before the Binet scale made its appearance. The question naturally suggests itself why Binet should have been successful in a field where previous efforts had been for ... Summary Of Changes
A comparison of the above list with either the Binet 1908 or 1911 series will reveal many changes. On the whole, it differs somewhat more from the Binet 1911 scale than from that of 1908. Thus, of the 49 tests below the "adult" group in the 1911 sc... Superior Adult 1: Vocabulary (seventy-five Definitions 13500 Words)
PROCEDURE and SCORING, as in previous vocabulary tests. At the "superior adult" level seventy-five words should be known. The test is passed by only one third of those at the "average adult" level, but by about 90 per cent of "superior adults." Ab... Superior Adult 2: Binet's Paper-cutting Test
PROCEDURE. Take a piece of paper about six inches square and say: "_Watch carefully what I do. See, I fold the paper this way_ (folding it once over in the middle), _then I fold it this way_ (folding it again in the middle, but at right angles to th... Superior Adult 3: Repeating Eight Digits
PROCEDURE and SCORING, the same as in previous tests with digits reversed. The series used are: 7-2-5-3-4-8-9-6; 4-9-8-5-3-7-6-2; and 8-3-7-9-5-4-8-2. Guard against rhythm and grouping in reading the digits and do not give warning as to the numbe... Superior Adult 4: Repeating Thought Of Passage

It doesn't make any difference whether you remember the exact words or not, but you must listen... Superior Adult 5: Repeating Seven Digits Reversed
PROCEDURE and SCORING, the same as in previous tests of this kind. The series are: 4-1-6-2-5-9-3; 3-8-2-6-4-7-5; and 9-4-5-2-8-3-7. We have collected fewer data on this test than on any of the others, as it was added later to the test series. As f... Superior Adult 6: Ingenuity Test
