The CogAT (Cognitive Abilities Test, Form 7) is the most comprehensive of the three big GATE screeners used in California. Unlike the OLSAT (one mixed score) or NNAT (nonverbal only), CogAT measures three different reasoning types separately — giving you a detailed cognitive profile, not just a single number.

Where CogAT is used in California

If you're not sure, contact your district's GATE coordinator. The list shifts every few years as districts switch publishers.

CogAT's three batteries

CogAT measures three distinct reasoning abilities. Each is tested in its own timed section, with three subtests inside each battery:

Verbal Battery

Quantitative Battery

Nonverbal Battery

CogAT levels by grade

Level Grade Total time
5/6K~80 min
71~90 min
82~95 min
93~98 min
104~98 min
115~98 min
126~98 min
13/14+7+~98 min

CogAT is significantly longer than OLSAT or NNAT. Often broken across multiple sittings — one battery per day. Stamina matters more than for the other two tests.

Standard Age Score (SAS) explained

CogAT reports a Standard Age Score (SAS) for each battery and an overall composite. Like OLSAT's SAI and NNAT's NAI, the SAS is centered at 100 and normed by age.

SAS Percentile Interpretation
85–115~16th–84thAverage
116–129~85th–97thAbove average
130–135~98thMost CA GATE cutoff
140+~99.5thHighly Gifted programs

Important: Some districts qualify based on a single battery score above 130, even if the composite is lower — recognizing that a child strong in nonverbal reasoning but weaker in verbal is still gifted. Ask your district about "single-domain" qualification.

A 4-week CogAT prep plan

CogAT-specific tip: the test is unusually long for a 3rd grader. Practice doing 30-minute focused sessions without breaks at least a week before the real test. Stamina is half the battle.
