Hi!

I'm afraid I'm confused: what test did your son take? Is SPECTRUM the name of the test? Or the program you're trying to get him into? Is it a gifted program or something else? Who administered the test?

There are IQ tests (the WISC and the Stanford-Binet are the two most common individual IQ tests in the U.S., though there are group tests like the CogAT, too, which tend to be less reliable). In a nutshell, these try to measure reasoning ability in some form or another.

There are also achievement tests (Woodcock-Johnson or Peabody, for example). These attempt to measure academic achievement or performance.

Did your child take one or both of these sorts of tests? Or is SPECTRUM something else entirely?

I'm sorry if I'm not helping, but I'm not clear about what it is that you're asking for help with. You might take a look at this article about assessment:

Maybe that helps a little? If not, feel free to post again.
