WISC-V scores for parents
A WISC-V report is a set of standard scores from a test a qualified person gave your child, not a single IQ floating on a page. This note helps a parent find the indexes, compare GAI with Full Scale IQ, and notice when one high number hides a split. It does not interpret your child, and it does not replace the examiner who wrote the report.
What the pages are for
The WISC-V is an individually administered test for children. The scores are age-normed standard scores, mean 100 and standard deviation 15, from the publisher’s norms. You will usually see a Full Scale IQ and several index scores. Names vary slightly by printout, but the broad groups are verbal comprehension, visual spatial, fluid reasoning, working memory, and processing speed. Subtest scaled scores sit under those indexes, often on a mean of 10. GAI on WAIS and WISC lists which subtests enter GAI by edition.
Read the composite the school actually asked for before you hunt for a higher one. Then read the indexes. A calm Full Scale number with one index far below the others is a different story from five indexes in a pile. The percentile on the report is the publisher’s percentile for that child’s age. Prefer it to a generic adult chart. The IQ score chart on this site is the plain normal curve, for when a report did not print a percentile, not a replacement for the norms.
If there is no WISC or WAIS in the house, the free IQ test is a personal, unnormed estimate for an adult sitting. It is not a way to score a child, and it must not be sent to school as a WISC.
GAI versus FSIQ
Full Scale IQ averages the core indexes, including working memory and processing speed. The General Ability Index keeps the reasoning side and leaves those two out. When memory or speed sit far below reasoning, GAI is often higher than FSIQ. The gap is subtraction. It is not a second, secret IQ that erases the low indexes. Those indexes still describe timed work and work that has to be held in mind.
A small gap can be real on a test with shared subtests and still be unsurprising. This site’s reading of 5, 10, and 15 points is on what a GAI vs FSIQ gap means. If both numbers are printed, you do not need to rebuild GAI from subtests. Paste them into the GAI calculator. If GAI is not printed, ask the examiner. Do not invent it from a blog table. Where to find GAI on a report shows the labels people miss.
Some gifted policies accept GAI when FSIQ was pulled down by memory or speed. Some do not. The handbook is the rule. The National Association for Gifted Children has a statement on using the WISC-V in gifted and twice-exceptional identification: NAGC, WISC-V statement. Read it as their position, then read your program’s position. This site does not decide eligibility.
Twice-exceptional: when the overall number hides a split
Twice-exceptional, often shortened to 2e, is a school and clinical description for a student who shows advanced reasoning or academic strength and also a disability or a large weakness that the overall score can mask. The mask works in both directions. A high Full Scale IQ can make a low index look like “not trying.” A low Full Scale IQ can make strong reasoning look like it is not there, which is one reason GAI is discussed at identification meetings.
A 2026 SAGE Open paper is one public source for that discussion. It reports work with 390 gifted and twice-exceptional children across seven US sites: SAGE Open, 2026. The sample size is the paper’s, not this site’s. The paper does not turn a parent’s spreadsheet into a classification. A 2e question needs the school team, the examiner, and the rest of the file: achievement, attention, language, vision, hearing, and what the day at school actually looks like.
- Write down each index, not only FSIQ. Note which one is the peak and which is the drag.
- If GAI and FSIQ both appear, subtract them and keep the sign. Positive means GAI is higher.
- Ask which composite the program uses, in writing, before you argue that the higher one should count.
- Do not practice WISC items with your child to move a cutoff. That can invalidate the next sitting.
What this website will not do with a child’s scores
It will not diagnose ADHD, dyslexia, autism, anxiety, or giftedness. It will not write a letter to the committee. It will not re-score the WISC. The cognitive profile note uses the same five-domain language for an adult estimate, including nine pattern names. Those names are for this site’s unnormed tasks. They are not WISC classifications. Putting a child’s name on them would be a misuse.
Adults who want a personal estimate, and who are not trying to file it, can take the free IQ test: about 30 minutes, no sign-up, an overall estimate and a profile name. Parents who already have the two official composites can stop at the calculator. If you are unsure whether an evaluation is warranted, ask the pediatrician or the school psychologist. A blog post that understands the columns is not the same thing as knowing the child.
The nine-task test on this site prints numbers on a conventional mean of 100 and a standard deviation of 15 so the parts of one sitting can be compared. That conversion is not a census norm, not age-normed, and not a diagnosis. A qualified examiner and the publisher’s manual are what a school, a clinic, a job, or a visa can use.
Common questions
What is a good WISC-V score?
On the 100/15 scale, 90 to 109 is the average band this site uses, 120 is superior, and 130 is very superior. “Good” for a program is whatever cutoff that program wrote down.
Should I look at GAI or FSIQ?
Read both. FSIQ is the usual summary. GAI is the reasoning summary with memory and speed removed. A large gap means one number is a poor description, not that the other number is fake.
Can this site’s test replace the WISC?
No. It is not for children, not age-normed, and not acceptable as a school score.
Where to go next
The GAIvsIQ laboratory keeps one URL for each job. This note does not replace the instrument it points to.
Ready when you are
No report yet, and the question is your own?
The free test is an adult estimate. It is not a WISC and not for a child’s school file.
