School Psychology/IQ tests


My son is 19 and we are applying for SSI for him. The Social Security Administration is requiring he have another IQ test. He had WISC-III tests at age 10 (Full IQ = 56, subsets ranging 55-72) and again at age 13 (Full IQ = 50, subsets ranging 55-62). He has never been mainstreamed and is currently in a program for disabled 18-22 year olds.

Now he will be taking the WAIS-IV. I would like to know how closely the WISC numbers will correspond to the WAIS numbers. I'm asking in case the examiner comes up with an out-of-left-field number. I do understand that IQ is a fluid sort of thing.

Hi Melissa,
While IQ is something that changes somewhat over time and each testing experience is a little different and so scores will naturally vary, the test is unlikely to come out extremely different. You may see some areas that have declined - or possibly had reached their peak at 13 and the scores have fallen because he is older now. You may also see some areas that have improved. Overall, though, I don't think you will see anything drastically different.
Best of luck to you,

I can answer most questions related to psychological evaluations including an explanation of the scores and the assessment measures. I can also answer most questions regarding special education eligibility, response to intervention (RtI), and recommendations and interventions for specific areas of disability including intellectual disability, learning disability, emotional and behavioral disorders, other health impaired, autism, and pervasive developmental disorder. I can also answer questions regarding Individual Education Plans (IEPs), and parent rights.I cannot determine if a child has a disability or not based on anecdotal information or assessment scores. I can also answer questions regarding the profession of School Psychology. I can tell you what School Psychologists actually do. I can also tell you about educational requirements though these differ somewhat by state.


As a graduate student, I interned at a psychoeducational facility for students with severe emotional and behavioral disorders as well as other disorders including specific learning disabilities, intellectual disabilities, and autism. Following my internship, I was hired full-time there as a school psychologist and worked there for several years. Since then I have worked as a regular school psychologist in a district mostly completing psychological evaluations and consulting with the Student Support Team (SST). I currently work as a contract psychologist for several metro Atlanta counties.
