IQ Test Ages 4–90

Free KBIT-2 Practice Test

The Kaufman Brief Intelligence Test, Second Edition (KBIT-2) is a quick IQ screener used by school psychologists to identify students who may benefit from further gifted or special education testing. Unlike the WISC-V (which takes 60–90 minutes), the KBIT-2 takes just 15–30 minutes — making it a common first-step screening tool.

Test Structure

What the KBIT-2 Covers

Three subtests measure both crystallized (learned knowledge) and fluid (novel problem-solving) intelligence. Together they form the IQ Composite score.

Verbal Knowledge

Tests vocabulary by having the child point to the picture that matches a spoken word (for young children) or by selecting the word that fits a category (for older children). A strong predictor of crystallized intelligence — knowledge accumulated through experience and education.

Riddles

The child is given a verbal clue and must identify the concept. Example: "It has four legs, barks, and lives with humans — what is it?" Tests verbal reasoning and the ability to integrate multiple pieces of information. The riddle format is unique to the Kaufman tests.

Matrices (Nonverbal)

Visual pattern completion using geometric shapes and symbols — no words or numbers. Tests fluid intelligence and abstract reasoning. The nonverbal format makes the Matrices subtest useful for assessing children from non-English-speaking backgrounds.

Study Strategy

Prep Tips for Parents

Understand it's a screener

A referral for full testing is good news — not something to fear. The KBIT-2 is a gateway, not a final verdict on your child's intelligence.

Build vocabulary through reading

Build vocabulary through wide reading and conversation. Verbal Knowledge is the most directly improvable subtest — every book your child reads adds to their vocabulary store.

Practice visual pattern puzzles

Practice visual pattern puzzles for the Matrices section. Tangrams, Sudoku (number patterns removed), or NNAT-style puzzle apps all strengthen fluid reasoning.

Keep the atmosphere calm

Stay calm — the test is short and low-pressure. The KBIT-2 is conversational and administered one-on-one by a psychologist, which many children find less stressful than group tests.

Ask for the full evaluation

Ask for the full WISC-V or SB5 if the KBIT-2 suggests giftedness. The KBIT-2 Composite is an estimate — only a comprehensive evaluation can confirm giftedness for program placement.

Common Questions

Frequently Asked Questions

What is the KBIT-2?

A brief IQ screener measuring verbal knowledge (Verbal Knowledge + Riddles) and nonverbal reasoning (Matrices). Takes 15–30 minutes. Mean 100, SD 15.

How is KBIT-2 different from WISC-V?

The KBIT-2 is a screener — it gives a quick estimate of intelligence. The WISC-V is a comprehensive evaluation with 5 index scores and 10+ subtests taking 60–90 minutes.

What is a good KBIT-2 score?

115+ (84th percentile) is above average; 125+ (95th percentile) is a strong indicator for gifted referral; 130+ (98th percentile) is the typical gifted threshold.

Who administers the KBIT-2?

School psychologists, educational diagnosticians, or licensed psychologists. Available in school settings for initial screening.

What happens if my child scores high on the KBIT-2?

The school psychologist will typically recommend a full psychoeducational evaluation (WISC-V or Stanford-Binet V) to confirm and document giftedness for program placement.
