Testing and Assessment
"If something exists, it exists in some amount. If it exists in some
amount, then it is capable of being measured." Rene Descartes, Principles
of Philosophy, 1644
"Assessing gifted children is similar to and different from assessing other
types of children. Though areas to be assessed are similar for all, for gifted
children, the assessment techniques and tests require special characteristics.
While most professionals are trained to assess many kinds of children, few are
specifically trained to assess in this particular area. The general perception
is that these youngsters, with abilities and strengths in many areas, have no
special needs, educational or otherwise, that merit serious clinical
attention. For this reason, it is important that parents who suspect that
their child may be gifted search for a professional with experience in working
with this population..." Julia B. Osborn,

by John D. Wasserman, George Mason University
- Flynn effect has not yet been adequately demonstrated for all levels of

there is no substantive evidence for its validity with high ability

as We Can Get?: Gains on certain tests of intelligence are ending in some
David Schneider, American
- Psychometricians have long been aware of a phenomenon called the Flynn
effect—a widespread and long-standing tendency for scores on certain tests
of intelligence to rise over time. And now they have another curiosity to
ponder: The tendency for intelligence scores to rise appears to have ended
in some places. Indeed, it seems that some countries are experiencing a
Flynn effect with a reversed sign...

Peter W. D. Wright and Pamela Darr Wright,
- (Written for special education parents, but just as valuable for gifted

they must understand the law and their rights. Few parents know that they must
also understand the facts. The "facts" of their child's case are contained in
the various tests and evaluations that have been administered to the child.
Changes in test scores over time provide the means to assess educational
benefit or regression. Parents who obtain appropriate special educational
programs for their children have learned what different tests measure and what
the test results mean...

Accurate Assessments of High Levels of Giftedness by Linda Silverman and Kathi Kearney
- One unique problem for parents of highly gifted children is the
impossibility of gaining accurate information about the level of their
children's abilities, given the low ceilings on modern tests. None of
these tests can capture the full range of abilities of the extraordinarily
gifted because the children's abilities extend beyond the upper limits of
the tests (requires Adobe Reader)

Discrepancies) by Shannon Pratt (subscription required)
- Despite attempts to develop a test useful for determining giftedness,
there were several early indications that the test was not operating in the
expected manner. The gifted sample included in the validity studies received
a mean Full Scale score of 123.7--over 6 points below the general standard
of 130 for gifted-program participants. In an additional study Riverside
documented that students performing at a prodigious level received a mean
score of 130, a score much lower than expected. In addition to the lower
means, it seems odd that a sample made up primarily of moderately gifted
students would only score 6 to 7 points below a sample in the profoundly
