Jeffco Public Schools gifted and CogAT guide.

Jefferson County Public Schools, known as Jeffco, identifies gifted students using the CogAT, the Cognitive Abilities Test, which covers verbal, quantitative, and nonverbal reasoning.

This guide is written for Jeffco parents in Golden, Lakewood, Arvada and across the county who want to know when testing happens, what the district actually does with the score, and what "body of evidence" means in practice.

What Jeffco says about identification

The CogAT is used as a universal screener, which means it is given to an entire grade rather than only to students someone has flagged. That matters for equity: universal screening is the main way districts catch capable students who were never referred, including multilingual learners and students whose classroom performance does not yet match their reasoning.

Jeffco names the 95th percentile, on age or grade norms, as the marker it looks for. It also states plainly that no single score qualifies or disqualifies a student, and that identification rests on a body of evidence. Those two statements are not in conflict, but parents often read only the first. A child at the 93rd percentile with strong supporting evidence is not out of the conversation, and a child at the 96th is not automatically in it.

Placement into a GT Center, which is a different decision from identification, uses a separate marker: an 88th percentile composite or domain score.

The CogAT's Nonverbal battery is the closest in format to the NNAT®: visual pattern and spatial reasoning with no reading demand. The Verbal and Quantitative batteries ask about word relationships and number reasoning instead, so a 2nd grader taking the full CogAT is doing three genuinely different kinds of thinking rather than the same task three times over.

Why the fifth grade screen catches families by surprise

The 5th grade screen only applies to students without a previous cognitive score, which in practice usually means children who joined Jeffco after 2nd grade. If your family moved into the district in 3rd or 4th grade, your child was not part of the universal 2nd grade screen and their first Jeffco cognitive assessment will be in 5th grade.

That is worth knowing because those families often assume the window has already passed. It has not. It is just later, and it is the one that counts.

Questions Jeffco parents should ask

1. What is this year's CogAT testing date for my child's school?
2. Was my child included in the screen, especially if we moved into the district after 2nd grade?
3. Beyond the CogAT, what goes into the body of evidence here?
4. When and how will we get results?
5. What is the difference, in services, between being identified and being placed in a GT Center?
6. If my child is close to the marker but not identified, what is the path to being looked at again?

Our broader questions to ask your school guide can help you turn those into one clear conversation with the office or program contact.
