Overview & Quick Facts
The Cognitive Abilities Test (CogAT) is the most widely used gifted screening test in the U.S., measuring verbal, quantitative, and nonverbal reasoning across 9 subtests. This guide covers everything: what's tested, how it's scored, and how to prepare.
Quick Facts
3 Batteries
Key Takeaway
Each battery scores independently. A child can be strong in Nonverbal but average in Verbal — knowing the battery breakdown helps you target prep time wisely.
What the CogAT Measures
The CogAT does not test what a child has learned in school. It tests how a child reasons — their ability to find patterns, form concepts, and solve novel problems. This is why it can identify gifted potential independent of school performance.

Sentence Completion
Worth approximately 11% of the total CogAT composite score. A sentence with one word missing — choose the word that best completes the meaning.
Key Takeaways
- ›Context clues in the sentence almost always point to the correct answer
- ›Strong vocabulary is the #1 predictor of performance on this subtest
- ›Wrong answers are often near-synonyms that don't quite fit the context
What It Tests
Students must know what words mean to select the right one. Daily vocabulary exposure — reading, conversation, word games — is the most effective prep.
Even if a student doesn't know all four answer choices, the sentence's tone, subject, and surrounding words narrow down the best fit. Teach your child to read the whole sentence before looking at choices.
The missing word must grammatically fit — verb tense, part of speech, singular/plural. A word that sounds plausible but is the wrong part of speech is always wrong.
Example Question Format
"The dog was very ___ after playing in the park for three hours."
Strategy: "three hours" signals fatigue. "Exhausted" is the only word matching that context.
How to Practice
- ›Learn 5 new vocabulary words per day with flashcards
- ›Cover the answer choices and predict the missing word first
- ›Read aloud daily — books slightly above grade level
- ›Discuss word meanings and ask "what other word could work here?"
Verbal Analogies
Worth approximately 11% of the total score. A:B :: C:? format — identify how the first pair relates, apply that relationship to find the missing fourth word.
Key Takeaways
- ›Name the relationship before looking at C — "A is a type of B"
- ›There are 8 core relationship types — learning them speeds up recognition
- ›Wrong answers often use the correct words but the wrong relationship
8 Core Relationship Types
finger : hand :: toe : foot
pen : write :: scissors : cut
hot : cold :: fast : slow
happy : joyful :: sad : sorrowful
robin : bird :: salmon : fish
cat : kitten :: dog : puppy
window : glass :: desk : wood
rain : flood :: drought : famine
Example Question
Cat : Kitten :: Dog : ___
Relationship: adult animal → young animal. Apply to dog → puppy.
Verbal Classification
Worth approximately 11% of the total score. Three words share something in common — choose the fourth word that belongs to the same category.
Key Takeaways
- ›Find the most specific category — not just "things" but "flying vertebrates"
- ›All three given words must share the same specific attribute — not just two
- ›Distractors often share one feature but not all — check all three
Example Question
Eagle · Sparrow · Penguin · ___
All three are birds. Bat has wings but is a mammal. Owl is also a bird.
Strategy
- ›State the category out loud: "They are all ___"
- ›Be as specific as possible — check each answer candidate against all three given words
- ›Category games and nature/science reading build the domain knowledge needed here
Number Analogies
Worth approximately 11% of the total score. Two number pairs share a mathematical relationship — find the number that completes the third pair.
Key Takeaways
- ›Figure out the rule from the first two pairs before looking at the third
- ›Rules can be +, −, ×, ÷, squaring, or a combination
- ›Verify the rule works for BOTH given pairs before applying to the third
Example Question
[2 → 6] [4 → 12] [5 → ?]
Rule: × 3. Check: 2×3=6 ✓, 4×3=12 ✓, so 5×3=15.
Number Puzzles
Worth approximately 11% of the total score. An equation with a missing value — find the number that makes the equation true.
Key Takeaways
- ›Think of equations as a balance scale — both sides must be equal
- ›Use inverse operations: if + is shown, subtract to find the unknown
- ›Always verify: plug your answer back into the equation
Example Question
? + 14 = 23
23 − 14 = 9. Verify: 9 + 14 = 23 ✓
Number Series
Worth approximately 11% of the total score. A sequence of numbers following a pattern — identify the rule and find the next number.
Key Takeaways
- ›Write the differences between consecutive terms first
- ›If differences aren't constant, look for a ratio (geometric) or alternating pattern
- ›Some series have two interleaved patterns (odd positions, even positions)
Pattern Types
3, 7, 11, 15, ___ (rule: +4 each time → 19)
2, 4, 8, 16, ___ (rule: ×2 each time → 32)
1, 10, 2, 20, 3, 30, ___ (odd positions: 1,2,3,4; even positions: 10,20,30,40 → answer: 4)
Figure Matrices
Worth approximately 11% of the total score. A 2×2 or 3×3 grid of shapes with one blank cell — identify which shape completes the visual pattern.
Key Takeaways
- ›Look for rules that apply to BOTH rows and both columns in a 2×2
- ›Common rules: rotation, reflection, size change, color/shading swap, adding/removing elements
- ›Practice with real paper and pencil — drawing the transformation helps internalize it
Transformation Types
Shape rotates 90°, 180°, or 270°. Check which direction (clockwise vs. counterclockwise).
Shape is flipped horizontally or vertically. Look for a "mirror axis" in the pattern.
Shapes get progressively larger or smaller across rows or columns.
Filled ↔ hollow, or color changes in a predictable pattern.
Number of dots, lines, or sides increases or decreases by a fixed amount each cell.
Paper Folding
Worth approximately 11% of the total score. A piece of paper is folded, holes are punched — predict what the unfolded paper will look like.
Key Takeaways
- ›Each hole punched creates a mirror-image hole on the other side of each fold
- ›Work backwards: unfold in reverse order, reflecting holes across the fold line
- ›Physical practice (actual paper folding) is the most effective prep for this subtest
How to Practice
- ›Fold paper, punch holes with a pencil, unfold and verify the pattern
- ›Origami builds the same mental spatial manipulation skills
- ›Work paper-folding worksheet problems daily for 2 weeks before the test
- ›Practice counting fold layers: 1 fold = 2 layers, 2 folds = 4 layers
Figure Classification
Worth approximately 11% of the total score. Three shapes share a visual characteristic — find the fourth shape that belongs to the group.
Key Takeaways
- ›Find the attribute shared by ALL THREE shapes, not just two
- ›Check multiple attributes: shape type, number of sides, shading, size, orientation
- ›Distractors share one attribute — you need the answer that shares ALL
Attribute Categories
All triangles, all quadrilaterals, all curved shapes, etc.
All 4-sided, all 6-sided, all with an odd number of sides.
All solid, all hollow, all striped in the same direction.
All shapes with a vertical line of symmetry, all shapes with 2+ axes of symmetry.

Frequently Asked Questions
What is the CogAT?
The Cognitive Abilities Test (CogAT) measures reasoning and problem-solving skills across three batteries: Verbal, Quantitative, and Nonverbal. It is the most widely used gifted screening test in U.S. schools.
What grades take the CogAT?
The CogAT is administered to students in grades K–12, though most gifted screening happens in grades 2–3. Levels 5–6 cover kindergarten; Level 17/18 covers grades 11–12.
What is a good CogAT score for gifted programs?
Most gifted programs require a score at the 90th percentile or above (SAS 120+). Some highly competitive programs use the 95th or 98th percentile. Cutoffs vary by district.
How long does the CogAT take?
The full battery takes approximately 2.5–3 hours and is typically split across two sessions. Each subtest takes about 10–12 minutes.
Can you prepare for the CogAT?
Yes. The CogAT tests reasoning, not memorized content, but practice helps children become familiar with question formats, reduce anxiety, and build speed. Start 4–6 weeks before the test.
Is the CogAT the same as an IQ test?
No. The CogAT measures academic reasoning ability while IQ tests (WISC-V, SB5) measure a broader cognitive profile. CogAT is group-administered; IQ tests are individually administered by a psychologist.
