- Thousands of 4-year-old children who appear gifted have the pleasure of taking a 30-minute test that determines the fate of the rest of their schooling (and lives). Only children who match the teacher's preconceived notion of what a gifted child looks like will get nominated and have the opportunity to prove their worth. Of course, parents can also nominate their own child, but parents aren't nearly as aware of the child's inclinations in school as the teacher.
- The primary test that is used to identify giftedness is the Naglieri Nonverbal Ability Test (NNAT-2). This test has been advertised as "culture neutral", but there is no such thing as a culture-neutral test of cognitive ability. Carol Carman and Debra Taylor found that even after taking into account ethnic differences, children from low-SES {socio-economic status} families were half as likely as other children to be identified as gifted on the first edition of the NNAT.
- Though the NNAT-2 is advertised as a measure of "nonverbal ability", it actually measures only a subset of nonverbal ability: figural nonverbal reasoning. Figural reasoning tests use arbitrary shapes such as triangles, circles, squares and stars to measure nonverbal fluid reasoning. There are varied ways of measuring nonverbal fluid reasoning, however, including the use of artwork depicting objects other than spatial forms such as apples, soccer balls, shoes, hammers and fire engine trucks. Therefore, no only does the NNAT-2 represent a subset of the total domain of fluid reasoning, but it also represents a subset of nonverbal fluid reasoning. In other words, it tests only a subset of the skills that contribute to school success, let alone real-world success.
- The NNAT-2 is often measured in a group setting. Combine the high-stakes stress of the testing situation, the confusing nature of nonverbal test directions (despite being advertised as "simplified"), and the lack of a trained clinician who can form a personal connection with the child and you have a recipe for disaster (particularly for children from a different culture). There's simply no opportunity for intelligent testing (see Chapter 2).
- There are very few practice items on the test, so children who have prior experience with the structure of the test and the strategies that are important for performance are at a distinct advantage. Children who can afford prior practice materials will be at an advantage. Therefore, those who are already at a disadvantage in their opportunity to learn in school (such as lower-SES children) are even further disadvantaged in their opportunity to improve their test performance that could serve as a gateway to improved learning outcomes. Catch-22. To give you an idea, at Bright Kids NYC you can receive eight, 45-minute individual test prep sessions for $1000; at NYC Gifted, you get 12-week sessions for $1,399.
- Even if a student does qualify for gifted identification, she still may not be able to get into one of the five coveted gifted-and-talented schools in the city because she didn't win the lottery.
- Have I mentioned yet that cognitive ability fluctuates most dramatically in youth, due to genuine brain maturation and enriching experiences (see Chapter 10)?
- Did I mention these are 4-year-olds?
"The economist Raj Chetty and colleagues looked at the life trajectories of nearly 12,000 children who were part of a large-scale education program in the 1980s based in Tennessee called Project Star. Although they found that the effect of good teaching, as measured by test scores, almost completely disappeared by junior high, a different story emerged when they checked in on the study participants as adults (age 30).
Those adults who did better in preschool were more likely to go to college and to attend a higher ranked college, were less likely to be single parents, and were more likely to save for retirement than those with similar backgrounds who did not do as well in preschool. Some people would say that these outcomes are more important than test scores. Teaching quality turne dout to be a particularly important factor in preschool performance: students who had more-experienced teachers had high earnings as adults. Factors such as class size and the socioeconomic status of peers had an effect on preschool performance, but neither of these factors explained differences in preschool performance as much as good teaching. One of the authors of the study, Emmanuel Saez, estimated that a terrific kindergarten teacher is worth about $320,000 a year, if you considered the additional monetary value a full class of students with a good preschool teacher can expect to earn throughout their careers. This figure doesn't even take into account social gains, such as better health and less crime".

Scott Barry Kaufman does find value in IQ tests, intelligently administered, as a diagnostic tool, to help find the right interventions for children with problems, gifted or not. But that is not e.g., what "The Bell Curve" by Murray and Herrnstein was all about, was it? It is not what the people who talk about "average national IQ" are all about, is it? None of that BS that "their motives are ignoble but their science is sound", please!

One interesting result I read of recently was a study that showed that motivating kids with monetary rewards had impressive effects on their scores on IQ tests. It's clear that genetics has important effect on sprint speed. It would not be surprising if the same is true of IQ.
If an 18 year old had repeatedly run the 40 yard dash and never broke 6 seconds, it might be time to give up on his dream of playing cornerback in the NFL. If a four year old has a slow time, it's way too early.
