CogAT

Overview

The Cognitive Abilities Test (CogAT) is a reasoning assessment published by Riverside Insights and used by school districts across the US, most often as part of gifted and talented identification. Instead of checking subject knowledge, it looks at how a student reasons with words, numbers and shapes, through three batteries: Verbal, Quantitative and Nonverbal. CogAT is given in group settings inside schools, from Kindergarten through grade 12.

Who can apply

CogAT is not something a family signs up for directly. A school or school district buys the test from Riverside Insights and decides when and to whom it is given, as part of its own testing calendar. Depending on the district, this can mean universal screening of an entire grade, or testing limited to students referred for gifted and talented review. Because the district controls both the schedule and the eligible grades, a parent cannot book or pay for a CogAT session with Riverside directly; any questions about who sits the test, and when, are answered by the local school or district office, not by the publisher. The district, not the family, is Riverside's customer, and it is the district that bears the cost of the test materials and scoring.

Exam pattern

CogAT is published in ten levels that map to grade, so every student in a tested grade takes a level built for that age group:

Every level has the same three-battery structure, and each battery is split into three timed subtests of about 10 minutes each.

Verbal Battery

Tests reasoning carried through words: students complete analogies by working out the relationship between a pair of words and extending it to a new pair, and finish sentences by choosing the word that fits the meaning being built. At the youngest levels (Kindergarten to grade 2), the same reasoning is tested through pictures and read-aloud instructions rather than independent reading, so pre-readers are not penalised for limited reading skill.

Quantitative Battery

Tests reasoning with numbers rather than taught arithmetic: students extend a number series to the next term, work out the rule linking two pairs of numbers and apply it to a new pair, and balance simple number puzzles so both sides of an equation match.

Nonverbal Battery

Tests reasoning with shapes and figures, with no reading involved at any level: students complete a 2x2 grid of figures by spotting the rule connecting the top row and applying it to the bottom row, work out what a folded and punched piece of paper looks like once unfolded, and pick the figure that completes a set of shapes grouped by a shared property.

Marking and results

CogAT has no pass/fail cutoff and no penalty for a wrong answer; it is a norm-referenced test, so a student's score shows how their reasoning compares with same-age peers nationally. Each battery, and a Composite across all three, is reported as a Standard Age Score (SAS) scaled to a mean of 100 and a standard deviation of 16, alongside an age-based Percentile Rank from 1 to 99 and a Stanine from 1 (lowest) to 9 (highest). Riverside also reports an Ability Profile, which shows the pattern across the three battery scores (for example, stronger Nonverbal than Verbal) rather than just the single Composite number. Districts use these scores, usually together with other measures such as grades or teacher input, to set their own threshold for gifted and talented placement; Riverside's score report does not itself declare a student "qualified" or "not qualified."

Preparation tips

Because CogAT measures reasoning rather than taught content, studying vocabulary lists or extra arithmetic does not target what the test checks. What helps most is familiarity with the question formats and how to follow the test's spoken or written directions, which is why schools typically run a short official practice set with students before test day rather than assigning content revision. For the youngest levels, where instructions are read aloud and answers are picture-based, the most useful preparation is making sure a child is comfortable listening to directions and marking an answer within a time limit, not reviewing subject matter.
