Not Have a Clue about the WISC-V?

WISC-V: The Basics

The WISC-V is a set of short activities (like little games or puzzles) that help us understand how your child thinks and learns. It’s not about school grades or what your child has memorized—it’s about how their brain works in different ways.


1. Verbal Comprehension Index (VCI): “Word Power”

What is it?

This part checks how well your child understands and uses words.


Why is it called “Comprehension”?

Because it’s about understanding ideas and words, not just knowing facts.


How is it tested?


  • Similarities:
  • What happens? The examiner says two words (like “dog” and “cat”) and asks, “How are these alike?”
  • What’s the point? They’re not testing if your child owns a pet—they want to see if your child can find a connection (like “They’re both animals” or “They’re both pets”).
  • If your child doesn’t know cats or dogs? That’s okay! The examiner uses lots of different pairs, and it’s about thinking, not just life experience.


  • Vocabulary:
  • What happens? Your child is asked, “What does ‘bicycle’ mean?”
  • What’s the point? Can your child explain what a word means in their own words?
  • Analogy:
  • Think of this as a “talking and thinking” game, not a “trivia” game.


2. Visual-Spatial Index (VSI): “Picture Builder”

What is it?

This checks how your child sees and works with shapes and spaces.


How is it tested?


  • Block Design:
  • What happens? Your child gets real, colorful blocks and is shown a picture. They have to make their blocks look like the picture.
  • Is it on paper or with real blocks? With real blocks!


  • Visual Puzzles:
  • What happens? Your child sees a picture of a puzzle and has to pick which pieces (from a group) would fit together to make that puzzle.
  • Is it hands-on? This one is usually done by pointing or saying answers, not with real puzzle pieces.


  • Analogy:
  • Like building with LEGOs or doing a jigsaw puzzle.


3. Fluid Reasoning Index (FRI): “Pattern Detective”

What is it?

This checks how your child solves new problems and finds patterns.


How is it tested?


  • Matrix Reasoning:
  • What happens? Your child sees a pattern with a missing piece and chooses which option fits best (like a simple Sudoku or “what comes next?” puzzle).
  • Figure Weights:
  • What happens? Your child sees a picture of a scale with shapes on it and figures out how to balance it by choosing the right shapes.
  • Analogy:
  • Like figuring out the next shape in a pattern or balancing a seesaw.


4. Working Memory Index (WMI): “Mental Juggling”

What is it?

This checks how well your child can remember and use information for a short time.


How is it tested?


  • Digit Span:
  • What happens? The examiner says numbers (“5, 2, 9”) and your child repeats them back. Then, maybe in reverse (“9, 2, 5”), or in order (“2, 5, 9”).
  • Is this fair for dyslexic kids? If a child has trouble with numbers or language, it can affect their score, but there’s also a visual version (Picture Span).


  • Picture Span:
  • What happens? Your child sees a row of pictures (like a dog, a house, a tree), then has to point to them in the same order after they’re hidden.


  • Analogy:
  • Like remembering a short grocery list without writing it down, or playing “Simon Says.”


5. Processing Speed Index (PSI): “Brain Quickness”

What is it?

This checks how quickly your child can do simple tasks with their eyes and hands.


How is it tested?


  • Coding:
  • What happens? Your child gets a sheet with numbers and a “secret code” at the top (like 1 = ★, 2 = ●, 3 = ▲). They have to draw the right symbol under each number as fast as they can for two minutes.
  • What’s the point? It’s not about math or drawing—it’s about matching and speed.


  • Symbol Search:
  • What happens? Your child sees a row of symbols and has to find if a certain symbol is there, marking “yes” or “no” as quickly as possible.


  • Analogy:
  • Like playing a matching game or “Where’s Waldo?” against the clock.


Extra Tips and Answers to Common Parent Questions


  • Is it all done with paper and pencil?
  • Most subtests are hands-on or involve pointing, talking, or drawing. Block Design uses real blocks. Some are on paper.


  • Is it a test of what my child knows or how they think?
  • It’s mostly about how your child thinks, not just what they know. Some questions use real-life words or objects, but it’s about reasoning and problem-solving.


  • What if my child doesn’t know the answer?
  • That’s okay! The test is designed so that almost no one gets everything right. It’s about seeing how your child approaches different kinds of problems.


  • What does “coding” mean?
  • It’s not computer programming! It means using a key to match numbers and symbols quickly—like a secret code game.


  • What if my child has a learning disability?
  • Some parts may be harder (like Digit Span for dyslexic kids), but the test looks at lots of skills to get a full picture.


Summary Table: WISC-V Subtests in Plain English

Bottom line:


The WISC-V is a set of thinking games that show how your child’s brain works in different ways. It’s not about being “smart” or “not smart”—it’s about understanding how your child learns best, so you and their teachers can help them shine!

The term informed consent is tossed around frequently in special education—but parents are often left wondering: “What am I really entitled to know before I sign off?” The federal and state definitions may surprise you. According to federal law (34 CFR § 300.9), consent means that the parent: Has been fully informed of all information relevant to the activity for which consent is sought, In their native language or other mode of communication, and Understands and agrees in writing to carry out the activity. Massachusetts law, under 603 CMR 28.02(4), mirrors this but goes further, requiring that the parent understands the information and knows their consent is voluntary and revocable at any time. So, what does “fully informed” mean? That’s where nuance matters. The Office of Special Education Programs (OSEP) has clarified that parents need only have a general understanding of the proposed action—not a deep technical breakdown of every detail. In legal terms, this means understanding what is relevant to the decision at hand. What Is “Relevant” Information? In both law and common sense, relevance is about whether something matters to the decision you're being asked to make. In legal terms: It must make a material fact more or less likely to be true (see Laccetti v. Ellis, Gath v. M/A-Com). It must logically connect to a question that affects your child’s services or placement. If a school proposes an evaluation with six components but only conducts four, asking why the other two were omitted is relevant—because it could affect whether the evaluation provides a complete picture of your child's needs. Red Flags to Watch for: From Referral to Placement 1. Evaluation Requests: Ask What You’re Getting—and What You’re Not Before consenting to an evaluation: Ask for a description of each assessment. Clarify if any typically used subtests are being omitted, and why. Request examples of what the test measures and how it will be used. Avoid confrontational language. Try: “I’m not trying to delay anything—I just want to understand what’s being measured and why some parts may have been left out. Can you help me understand the relevance of each?” 2. IEP Goals: Ask How They Were Chosen When you’re reviewing IEP goals, ask: Were the goals based on the most current data? Do they directly connect to the evaluations or identified needs? Do they reference a method of instruction, or deliberately avoid naming one? If an IEE recommended a specific methodology (e.g., Orton-Gillingham for dyslexia or DTTC for apraxia), ask: “Given the IEE’s findings, I’d like to know why a different approach was chosen. What data supports the effectiveness of the selected method for my child’s profile?” Services Must Be Based on Peer-Reviewed Research—To the Extent Practicable Federal law (34 CFR § 300.320(a)(4)) requires that the IEP includes: “A statement of the special education and related services and supplementary aids and services, based on peer-reviewed research to the extent practicable…” Most parents aren’t aware they can—and should—ask: “Is this service or approach supported by peer-reviewed research?” “Could you provide a source or summary of research that shows this method is effective for children like mine?” This isn’t being difficult—it’s your right. And it helps the team stay accountable. Placement: Understanding the Peer Group One of the trickiest issues is group appropriateness—especially in districts that are understaffed. If your child is in a group setting, but their needs are significantly different from their peers, you have the right to ask how the grouping benefits your child. The Andover Case: A Tool Parents Can Use In Andover Pub. Schs., 117 LRP 17110 (SEA MA 04/20/17), the hearing officer ruled that: Parents can request sanitized IEPs (i.e., redacted of all identifying information) of proposed peers to assess appropriateness. FERPA does not block the release of de-identified IEPs. This means that if you're told a program is “a good fit” for your child, you can ask: “Could we see de-identified IEPs of the peer group to better understand the instructional levels being targeted?” Wrapping Up: Stay Curious, Stay Focused Informed consent is not about becoming an expert on educational methodologies or neuropsych testing. It’s about being empowered to: Ask why a service is recommended. Understand how your child’s needs are being met. Spot when things don’t add up—and push for clarification respectfully. Most importantly, it’s about framing questions around relevance, not resistance. When you tie your inquiry back to your child’s success, you're not being difficult—you’re being effective.

While adults have long known that children demonstrate a lack of maturity and underdeveloped sense of responsibility, leading to recklessness, impulsivity and heedless risk-taking, there is now scientific evidence that is recognized and accepted as true by the courts of this country: “Our decisions rest[] not only on common sense – on what ‘any parent knows’ – but on science and social science as well.” Miller v. Alabama, 132 S.Ct. 2455, 2464 (2012), quoting Roper v. Simmons, 543 U.S. 551, 569 (2005); see also Diatchenko v. District Attorney for the Suffolk District, 466 Mass. 655, 669 n.14 (2013). In short, before you assume your child will likely be found delinquent of a crime, you should consult with an experienced juvenile criminal defense attorney about the changing climate of juvenile criminal law.

You call your son’s school, tell the nice lady in the special education department that you suspect he has a learning disability and you want him evaluated. After a brief discussion about your concerns, you are told that you must provide the school with written consent before testing can commence. Not to worry, the helpful school official offers to mail you the form. She encourages you to return the signed form promptly so testing can begin. You anxiously await the form’s arrival in the mail. Three days later you receive the consent form. Attached to it is a post-it note instructing you where to sign. However, as you review the form, you notice that the section of the form entitled “list the recommended assessment(s)” is blank and that the “yes” box is checked for an “educational assessment,” a “health assessment” and a “psychological assessment.” You hesitate before signing. Your mother always warned you never to sign anything unless you understood it and you do not understand any of this educational jargon. However, you do not want to delay the testing. Should you sign it? The simple answer is your mom was right: You should not sign the consent form if you do not understand it. However, please know that you are not alone. Few parents understand that they have a right to make decisions about their child’s education based on “informed consent.” In Massachusetts, this means you have a right to be “fully informed of all information relevant to the activity for which consent is sought.” So, if the language appearing in the form leaves you asking questions, by all means, ask them! Indeed, ask questions until you and you alone are satisfied you have the information you need to make an informed decision. For example, consider asking for a list of all the assessments the school seeks to administer, a detailed description of each assessment and, to the extent the assessment has “sub-parts,” ask if any sub-part will be omitted from the testing. If so, ask them to explain the decision not to administer that sub-part. As a matter of fact, if you ever do not understand the school’s decision to administer or not administer an assessment or sub-part to an assessment, ask the school to provide you with an explanation for the decision. It’s your right! If your school responds that it is not required to explain itself, remind that school official that the legislative history for informed consent includes the following language: “A few commenters recommended adding a requirement to the definition of consent that a parent be fully informed of the reasons why a public agency selected one activity over another. Discussion: We do not believe it is necessary to include the additional requirement recommended by the commenter. The definition of consent already requires that the parent be fully informed of all the information relevant to the activity for which consent is sought.” In other words, to be “fully informed” a parent not only has the right to know whatassessment will be administered/not administered by the school, he or she also has the right to know why the assessment will be administered/not administered. So, don’t be shy. Ask, ask, ask……
