Your child's school sent home a letter about the CogAT. Or maybe a friend mentioned their kid is taking it. Either way, you're trying to figure out what this test actually is, what it measures, and whether preparation makes a difference.

Here's everything you need to know.

What does CogAT stand for?

CogAT stands for Cognitive Abilities Test. It is published by Riverside Assessments and is one of the most widely used assessments for identifying gifted students in the United States. Thousands of school districts use it every year to make placement decisions for gifted and talented programs.

What does the CogAT measure?

Unlike achievement tests (which measure what your child has already learned in school), the CogAT is designed to measure cognitive reasoning abilities — the mental processes used to learn and solve problems. Specifically:

Verbal reasoning — understanding relationships between words and concepts
Non-verbal reasoning — visual-spatial thinking using shapes and patterns (no reading required)
Quantitative reasoning — mathematical thinking and pattern recognition with numbers

The three areas are tested separately (called "batteries"), and scores are reported both individually and as a composite.

Which grades take the CogAT?

The CogAT is available for grades K–12, but the most common testing points for gifted program admission are grades 2, 3, and 4. Many districts test incoming second graders for gifted placement in third grade. Some districts test annually; others test only at specific grade levels.

Check with your specific school district to find out when and how testing is administered.

How is the CogAT scored?

The CogAT produces several types of scores:

Raw score — number of correct answers
Standard Age Score (SAS) — compares your child to other children of the same age; average is 100
Percentile rank — what percentage of same-age peers your child scored above; gifted programs typically require 95th percentile or higher
Stanine — a 1–9 scale; stanine 9 is the top ~4% of scores

Does practice actually help?

Yes — with an important nuance. The CogAT tests reasoning, not memorized facts, so cramming does not work. What does work is familiarity with question types andexposure to the reasoning patterns each question type requires.

A child who has never seen a figure matrix question will spend precious testing time figuring out what the question is even asking. A child who has practiced them knows exactly what to look for and can focus on the reasoning. Research suggests that 4–8 weeks of structured practice can meaningfully improve performance, especially for children who test poorly under unfamiliar conditions.

What's the best way to prepare?

The most effective preparation combines two things:

Regular practice — short daily sessions (15–20 min) are more effective than occasional long ones
Understanding explanations — when your child gets a question wrong, reading the explanation is where the real learning happens

The biggest weakness in most test prep materials is that they show answers without explaining the reasoning. That's why TestPrepKids includes a detailed explanation for every question — so your child understands the "why," not just the "what."
