What is a GAI Score? Understanding Your Child’s Cognitive Test Scores
What the GAI Score Means and How It Compares to FSIQ on IQ Tests
If your child has taken the WISC-V (Wechsler Intelligence Scale for Children® Fifth Edition) or the WPPSI-IV (Wechsler Preschool & Primary Scale of Intelligence™), you may have come across a score called the GAI, or General Ability Index. This score is an alternative representation of a child's intellectual abilities, placing less emphasis on working memory and processing speed compared to the FSIQ (Full Scale IQ).
When working memory and/or processing speed scores are significantly lower than other index scores—typically showing a 23-point or more discrepancy—the GAI score should be provided. It offers a clearer picture of a child's reasoning and problem-solving abilities without the impact of lower scores in these areas. For more detailed information about the GAI, consult resources provided by the test publisher, Pearson.

GAI vs. FSIQ: What’s the Difference?
Take a look at the example above. In this scenario, the working memory and processing speed scores are noticeably lower than the other index scores.
FSIQ (including all scores): 112
GAI (excluding working memory and processing speed): 127
Why Wasn’t My Child’s GAI Score Provided?
Not all children require the GAI to be calculated. The FSIQ is considered valid if all index scores, including working memory and processing speed, are relatively consistent. However, if your child’s profile shows significant discrepancies, the GAI may be a better representation of their cognitive abilities.
Some psychologists may overlook calculating the GAI, either due to lack of awareness or differing testing practices. If you believe your child’s scores warrant a GAI calculation but it wasn’t provided, you can request that the psychologist revisit the data and calculate it for you.
What Do Lower Working Memory and Processing Speed Scores Mean?
When children score lower in working memory and processing speed, it can indicate several possibilities:
Learning Disabilities or ADHD:
These conditions may affect a child’s ability to process and retain information quickly. A comprehensive evaluation may help confirm if this is the case.
Perfectionism or High Achievement:
Gifted children may work more slowly because they aim for precision, taking extra time to ensure their answers are correct.
Developmental Factors:
Younger children, especially those taking the WPPSI, may struggle to focus or sit still during testing due to their age and maturity. Retesting at an older age with the WISC-V can sometimes show improved scores as attention spans increase.
What Can You Do Next?
If your child’s profile indicates lower scores in working memory or processing speed, consider the following steps:
Rule Out Learning Disabilities or ADHD:
If your child’s scores align with potential signs of a learning disability or ADHD, seek further evaluation from a neuropsychologist or educational psychologist. These professionals can help identify if your child is twice-exceptional (2E).
Consider Interventions:
For ADHD or other diagnosed conditions, therapies, medications, or educational accommodations may help. Improved attention and focus often translate to better performance in subsequent evaluations.
Monitor Developmental Progress:
A child’s maturity level can impact test results. Reassess over time to observe changes as your child grows.
Collaborate With Schools:
For 2E students, meet with educators to create an individualized education plan (IEP) or 504 Plan to address both strengths and areas of need. Accommodations like extra time on tests or reduced emphasis on speed-based tasks can be crucial for success.
Ways to Help Your Child Improve Working Memory and Processing Speed
Improving these cognitive abilities takes time, patience, and a mix of targeted activities, daily habits, and emotional support. Here’s a list to help:
1. Incorporate Playful Memory Activities

2. Use Visualization Techniques
Help your child turn abstract information into pictures in their mind. For example:
If they’re studying the solar system, they can imagine themselves flying past each planet.
For lists, encourage them to create a mental story that ties the items together (e.g., a banana riding a skateboard to the grocery store).
Pair this with drawing or doodling what they imagine to reinforce the memory.
3. Teach Chunking for Big Tasks
Break Information Down: Teach your child to group items into smaller categories, like remembering a phone number in two parts instead of all at once. This is particularly helpful for studying or large projects.
Practice Lists: Start with short lists (e.g., three grocery items) and gradually build to longer ones, encouraging them to mentally group similar items.
4. Encourage Repetition and Recall
Regular Review: Have your child say new information aloud, write it down, or teach it to someone else. Teaching is one of the best ways to reinforce memory!
Active Recall: Quiz them on what they learned earlier that day or ask questions like, “What was your favorite part of the book we read this morning?”
5. Strengthen Sequencing and Processing Skills
Use activities like:
Putting events in chronological order (e.g., "What happened first, second, and last in today’s story?").
Playing games like Connect Four or puzzles that rely on pattern recognition.
Asking them to describe their morning routine step-by-step.
6. Create Opportunities for Timed Challenges
Set small challenges with a timer, like “How many simple math problems can you solve in one minute?” or “Let’s see how fast you can remember and spell these words.”
Gradually reduce the time to help them think faster without feeling overly pressured.
7. Build Healthy Habits
Sleep: Ensure they’re getting enough quality rest. Sleep is essential for memory consolidation and processing speed.
Nutrition: Fuel their brain with foods rich in omega-3 fatty acids (like salmon), antioxidants (berries), and whole grains.
Exercise: Physical activity improves blood flow to the brain. Activities that combine physical movement with mental tasks, like dance routines or sports, are particularly beneficial.
8. Practice Active Listening
Improve working memory by encouraging your child to listen carefully and then repeat what they heard. For instance:
After giving instructions, ask, “Can you tell me what we’re going to do first?”
Play listening games like “20 Questions” to help them focus on details.
9. Encourage Writing and Organization
Checklists: Help your child create daily to-do lists or reminders to practice prioritization.
Journal Writing: Writing down their thoughts, stories, or lessons from the day can strengthen memory and help them organize ideas.
10. Use Real-World Practice
Involve them in tasks that require memory, like following a recipe (remembering ingredients and steps) or planning a simple outing.
Create a “shopping memory game” where they try to recall a small list of items without writing them down.
11. Support Emotional Regulation
High stress or anxiety can hinder memory and processing speed. Teach relaxation techniques like deep breathing or mindfulness exercises.
Build their confidence by celebrating small wins and reminding them that everyone improves at their own pace.
12. Limit Overload
Avoid giving too many instructions or tasks at once. Start small and gradually increase the complexity.
Use visual aids, like charts or checklists, to reduce the load on their working memory.
13. Leverage Multi-sensory Learning
Incorporate sight, sound, and touch into learning. For example:
Use flashcards for sight.
Pair lessons with songs or rhymes for sound.
Let them handle objects related to the lesson for a tactile experience.
14. Model Memory Strategies
Show them how you memorize or organize information. For example:
“When I want to remember something, I write it down and say it out loud.”
Model problem-solving when you forget something, so they learn techniques like retracing their steps or using context clues.
15. Patience and Praise
Recognize their efforts, not just the outcome. Processing speed and memory develop over time, and consistent encouragement can make a huge difference.
Understanding the nuances of the GAI score can empower parents to better advocate for their child’s educational and developmental needs. Whether through targeted activities, appropriate evaluations, or school accommodations, focusing on your child’s unique strengths and challenges can set them on a path to success.
If you have any concerns or unanswered questions about your child’s scores, don’t hesitate to seek clarification from the evaluator or consult an expert in educational psychology.
