Hello all,
In 2015 my daughter, then 10, was tested for giftedness with the WISC-V. Her scores were:
FSIQ 129
GAI 134
VERBAL COMPREHENSION 142
VISUAL SPATIAL 105
FLUID REASONING 131
WORKING MEMORY 110
PROCESSING SPEED 89 (called her "personal weakness")

We had recently moved to the US from another country where she had attended school in that language and culture. It was felt at the time that she might have had even higher scores without the cultural differences, even though she is bi-lingual. Her Woodcock-Johnson scores also reflected the recent school/cultural change and were not reflective of her knowledge. So, the school denied admitting her to the gifted program.
She continued to be bored and dissatified with school.
We had her re-evaluted about a year later and her W-J scores were much higher. After she produced an exceptional research project they finally admitted her to the gifted program. However, there was really little differentiation or support in the regular classroom and nothing much happened in the gifted time 2-3 hours per week. Her disengagement continued to grow, culminating with her refusal this year to attend school. She homeschooled this year. She has always tested in the 98th/99th percentiles on the MAP tests.
She is now entering high school and I decided to have some testing done to try to address her disengagement and other issues.
She was tested with the Stanford-Binet with the following results:
FSIQ 109
NONVERBAL IQ 100
VERBAL IQ 117
ABBREV IQ 106
FLUID REASONING 109
KNOWLEDGE 120
QUANT.REASONING 103
VISUAL SPATIAL 111
WORKING MEMORY 97

Needless to say I was astonished at the lower numbers. The test administrator kept trying to convince me that the two test scores were "equivalent". I understand that the different test favor different apptitudes, but I cannot see how the two test scores can be equivalent. Can anyone advise about this?

Additionally, recently she participated in a research study with IQ testing as part of it and scored the following on the WASI-II:
VERBAL IQ 116
PERFORMANCE IQ 128
FSIQ 125

In this case it's strange that her verbal was lower when it has always been her great strength. The other two are a bit lower than the original WISC but generally in line. The fact that she had done this in the research study was the reason she was given the Stanford-Binet.

All thoughts appreciated.
