San Diego Unified School District identifies GATE students using the CogAT Screener, a shorter form of the Cognitive Abilities Test.
This guide is written for SDUSD parents, and it corrects two things you may have read elsewhere: the testing window is not in late spring, and the numbers 121 and 135 are not percentiles.
What SDUSD says about identification
All second grade students are universally screened with the CogAT Screener. Students who are new to the district in grades 3, 4 and 5 are also assessed, so a family moving into San Diego mid-elementary is not shut out.
| Test basics | What SDUSD parents should know |
|---|---|
| Test | CogAT Screener, a shorter form of the full CogAT |
| Screened grades | All 2nd graders; plus students new to the district in grades 3 to 5 |
| Window | Late January through February |
| GATE Cluster | Matrix score of 121 or higher recommended |
| GATE Seminar | Matrix score of 135 or higher recommended |
| Retest | Once, in 5th grade, automatic, with conditions |
| Consent | Varies by school; ask yours |

Why 121 and 135 are not percentiles
This is the part most often reported wrongly. SDUSD recommends a score of 121 or higher for GATE Cluster and 135 or higher for GATE Seminar. Those are not CogAT percentile ranks and they are not raw CogAT scores either. They are totals on a district matrix.
The CogAT standard score forms the base of that matrix, and then points are added for other factors, including English learner status, low income, having an IEP, relocation, and achievement data. In other words, two children with identical CogAT scores can end up with different matrix totals, by design. The matrix exists to widen identification, not to narrow it.
The practical consequence for a parent: do not compare your child's CogAT percentile against 121 and conclude anything. Ask the school for the matrix total.
The 5th grade retest, and who gets it automatically
SDUSD offers one retest, in 5th grade, and families do not have to request it. A student is included if they scored above the 85th percentile on the CogAT and reached Above Standard in both English language arts and math on the 4th grade CAASPP.
That combination is worth reading closely, because it means a strong CogAT score alone does not trigger the retest, and strong CAASPP results alone do not either. A child needs both. District board background from 2015 caps students at one retest.
One thing SDUSD does not settle: consent
The district site says nothing about whether testing is opt-in or opt-out, and its schools disagree in public. One school's GATE page states that parents are required to sign a permission form for their child to be tested. Another states that information and an opt-out form will go home.
Those are opposite defaults, and which one applies to your child determines whether doing nothing means tested or not tested. This is worth a direct question to your school office rather than an assumption.
Questions SDUSD parents should ask
- Does our school use a permission form, or an opt-out form?
- What is my child's actual testing date inside the January to February window?
- What was my child's matrix total, not just their CogAT score?
- Which factors added points to that matrix for my child?
- Is my child on track for the automatic 5th grade retest, meaning above the 85th percentile and Above Standard in both CAASPP subjects?
- What is the difference in practice between GATE Cluster and GATE Seminar at our school?
Our broader questions to ask your school guide can help you turn those into one clear conversation with the office or program contact.
Frequently asked questions
When does San Diego Unified test for GATE?
The district states that starting in 2026, students are assessed during a testing window typically held from late January through February. Older school pages describing late spring testing are out of date.
Which grades does SDUSD screen?
All 2nd graders are universally screened with the CogAT Screener. Students who are new to the district in grades 3, 4 and 5 are also assessed.
What score does a student need in San Diego Unified?
The district publishes 121 or higher as the recommendation for GATE Cluster and 135 or higher for GATE Seminar. Importantly these are matrix scores, not CogAT percentiles. The CogAT standard score is the base, and points are added for factors such as English learner status, low income, an IEP, relocation, and achievement.
Do I need to sign a permission form for SDUSD testing?
It varies by school and the district does not publish one rule. Some school pages describe a permission form parents must sign, others describe an opt-out form sent home. Ask your school which applies.
Can a San Diego Unified student be tested again?
There is one retest, in 5th grade, and it is automatic. A student qualifies for it by scoring above the 85th percentile on the CogAT and reaching Above Standard in both English language arts and math on the 4th grade CAASPP. No parent action is needed.
Does GateBuddy offer CogAT practice for San Diego families?
Not yet. GateBuddy currently offers NNAT practice. CogAT practice is planned; join the waitlist on this page to be notified when it launches.
