Gifted and talented tests explained, from CogAT to SHSAT

American families meet two quite different kinds of test. One kind arrives uninvited: a school letter saying that every second grader will sit a reasoning screener next month. The other kind is chosen: a twelve-year-old deciding whether to register for a specialized high school exam or a Catholic high school test. This page sets both side by side in the organisers’ own words, then points to our page on the one you face.

The short answer

US gifted programs usually screen with an ability test: the CogAT (Riverside Insights), NNAT3 or OLSAT 8 (Pearson), sometimes alongside the Iowa Assessments; NYC Gifted and Talented uses no test at all. Selective high schools use entrance tests: the SHSAT, Hunter's own exam, MAP Growth in Boston, the HSPT, TACHS, ISEE or SSAT. Modern Age Coders teaches the reasoning and math underneath them live online, in a batch or 1-on-1.

Where we can help

Three courses for the thinking these tests sample

One for young children facing a screener, one for middle schoolers aiming at an entrance test, and one that grows problem solving at any age in between.

All tests

What are the main gifted and selective school tests in the US?

Thirteen tests and processes cover most of what a US family meets between kindergarten and grade 9: four screening tests, two district processes, and seven routes into selective or private high schools.

Gifted screening

Which test does a gifted and talented program use for screening?

Most public districts pick one ability test, give it to every child in one grade, and treat the score as one piece of a larger picture. The four names below cover nearly every district letter, and two pages explain the processes around them.

The four screening tests

If the letter names the Cognitive Abilities Test, our CogAT reasoning and readiness page walks through its verbal, quantitative and figural batteries and the way four districts read the results, with paper-folding and sorting games for ages 6 to 9.

A child who is still learning English often meets the Naglieri test instead. The NNAT3 guide explains why a picture-only test with pictorial directions suits mixed-language classrooms, and teaches children to track what moves and what stays fixed in a design.

Connecticut and California districts are among those that still give the Otis-Lennon. Our OLSAT 8 page focuses on the listening and sequencing habits a young child needs when directions are read aloud once.

The Iowa Assessments math page is the odd one out: it covers an achievement test, so it teaches real grade 1 to 5 math, from reading a bar graph to subtracting across zeros, rather than reasoning play.

The processes around the tests

For families whose district letter names no test at all, or names several, the gifted and talented test prep guide lays out the usual sequence from universal screening to a placement team, and why a single score rarely decides anything.

New York City is the exception that confuses everyone. Its NYC Gifted and Talented guide covers the 2027 application windows, how a report card grade converts to the 1 to 4 scale, and what kindergarten teachers look for, because the city no longer tests at all.

When a screening test usually arrives, by grade (our summary of the district pages quoted on this site, read 31 October 2026)
GradeWhat some districts doExample from a published district page
KindergartenNYC families apply for G&T entry; no testNYC Public Schools: kindergarten window December 9, 2026 to January 22, 2027
Grade 1A nonverbal screener for every childFort Worth ISD: "universal screener for all first graders" (NNAT3)
Grade 2The most common universal screening yearSan Ramon Valley (CogAT), Edmonds (NNAT3), Charlotte-Mecklenburg (CogAT with i-Ready)
Grade 3A second chance, or the first screen in some townsDarien Public Schools: the OLSAT in "grades 3 and 5"
Grades 1 to 4NYC G&T entry by report cardGrades 1 to 4 window April 19 to May 7, 2027
Grade 6A later screen for middle school servicesEdmonds School District screens grade 6 with the NNAT3

New York City has no G&T test. The city’s Gifted and Talented page says the programs "offer accelerated instruction" to eligible elementary students, and describes eligibility by pre-K teacher evaluation, by interview after which "early childhood education experts nominate eligible applicants", or, for grades 1 to 4, by report card grades "of a 3 or 4, or the equivalent". It mentions no admissions test anywhere. A family in New York who is offered a paid G&T test course should know that no such test exists in the current process.

Prep or not

Should you prepare a child for a gifted test?

Not by drilling. Several districts and publishers say in writing that they discourage commercial preparation, and their reasons are worth reading before anyone spends money. What does help is a calm child who has seen the format once and who reasons, counts and builds for fun.

What districts and test organisers say about preparation, in their own words (pages read 31 October 2026)
OrganiserTestWhat they say
San Ramon Valley Unified School District, CaliforniaCogAT"Our district does not recommend any materials for CogAT preparation." Students are encouraged toward "minimal test preparation".
Edmonds School District, WashingtonNNAT3"excessive preparation for the NNAT isn't recommended"; asked whether a child should study first, the district answers "No".
Darien Public Schools, ConnecticutOLSAT"No one score on any one measure determines placement."
Hunter College High School, New YorkEntrance examThe school "does not endorse any test preparation service or agency".
Riverside Insights and three diocesesTACHSRiverside Insights, with the dioceses, "does not encourage or endorse coaching or tutoring programs", and "Official TACHS practice tests are not published or provided".
Scholastic Testing ServiceHSPTAdvises families to "avoid expensive preparation materials" and to trust a "well-rounded education".

Why the organisers say this

A reasoning screener is meant to show how a child thinks on an ordinary morning. Rehearsing look-alike puzzles can lift the score without changing the thinking, and a child may then land in a class paced beyond them.

Outside scores are often refused too. Charlotte-Mecklenburg says private testing is not accepted for gifted identification, and St. Louis Public Schools says assessments from other districts or independent examiners are not accepted. Paying for a private sitting rarely buys a second route in.

What honest readiness looks like

Familiarity with the format, once: the district’s own sample sheet, or the publisher’s free family guide, so that the screen, the pictures or the read-aloud directions are not a surprise.

Broad reasoning, number sense and spatial play, for months rather than days: sorting objects and saying why, building and folding, noticing patterns on a calendar, splitting numbers into parts. These habits help in class whether or not a program place follows, which is why our young-learner lessons are built on them and never on copied items.

Exam schools

Which entrance test do selective and private high schools use?

It depends on the city and the kind of school. Public exam schools in New York and Boston run their own processes; Catholic high schools usually use the HSPT, or the TACHS in the New York dioceses; independent schools ask for the ISEE or SSAT. Six pages here cover them.

Public exam schools

Eighth graders in the five boroughs who want Stuyvesant, Bronx Science, Brooklyn Tech or the other testing schools should start with SHSAT math prep and tutoring, which covers the move to a computer-adaptive format in fall 2026 and what that means for pacing and skipping.

Hunter College High School takes students only at grade 7, through an exam it writes itself. Our Hunter entrance exam math page is for sixth graders, and works on five-choice elimination and calculator-free pattern spotting before the January 27, 2027 sitting.

Boston is different again: no Boston-written exam, but a composite of a MAP Growth score and grades. The Boston exam schools math guide explains that formula and uses weighted averages as real math practice.

Catholic and independent schools

Many Catholic high schools outside New York use the Scholastic Testing Service battery. HSPT math prep concentrates on its two number subtests, quantitative skills and mathematics, with number series and quantity comparisons.

Families applying to Catholic high schools in Manhattan, the Bronx, Staten Island, Brooklyn, Queens or Long Island meet the TACHS instead. Our TACHS math page covers the at-home online sitting and when the new built-in calculator is worth using.

Independent day and boarding schools ask for one of two tests from the same nonprofit. The ISEE and SSAT math prep page takes each level in turn, with number sense and comparison strategy for both.

ISEE and SSATGrades 2 to 12 (ISEE), grades 3 to 11 sit the SSATSee the organiser's pageFall, winter and spring testing seasons for the ISEE; see admission.org

One surprise for parents: NYC Public Schools says the SHSAT "is not used to determine admissions to LaGuardia High School". Another: the Hunter, SHSAT and HSPT math sections allow no calculator, so accurate mental arithmetic matters more than any trick.

Advanced programs

What programs are there for advanced students beyond school gifted classes?

Talent searches, online schools and acceleration policies serve students who need more than their grade offers.

After Duke TIP

Duke’s provost notes that TIP and its Academic Talent Search were "permanently closed" in 2020. Our Duke TIP alternatives page compares the university programs families now use, such as Northwestern’s Center for Talent Development, which says "No test scores or portfolio materials needed to enroll." at its open tier.

An online high school

Stanford Online High School serves students in grades 7 to 12 and states that "Admission to Stanford OHS is competitive". Our Stanford OHS math page looks at its proof-centred courses and the January 7, 2027 deadline.

Acceleration at school

Texas now enrolls sixth graders in the top 40 percent on the Grade 5 Math STAAR in an advanced track automatically. The accelerated math program page maps what compacted math squeezes together, grade 7 idea by grade 8 idea.

How to choose

How do you find out which test your child needs?

Start from the decision, not the test. Work out who decides the place your child wants, read that body’s own page, and only then pick a member page here. Six steps, then one worked example of ours.

  1. Name the decision. Is this a gifted service inside your child’s current school, a separate public school with an entrance process, or a private or Catholic school? Each has a different decider.
  2. Find the decider’s own page. For gifted services that is your district’s advanced learning or GATE page; for exam schools, the city school system; for Catholic schools, the diocese or the school; for independent schools, the admissions office.
  3. Read the test name and the grade. Write down exactly what the page names (CogAT Screening Form, NNAT3, MAP Growth, HSPT) and which grade sits it. Our table above shows what each name means.
  4. Check whether there is a test at all. NYC Gifted and Talented has none, and Boston weighs grades more than the test. A family can lose months preparing for the wrong thing.
  5. Read what the decider says about preparation. If the district says no materials are recommended, take it at its word; if the school publishes free samples, use those and nothing imitation.
  6. Open the matching page here. Each quotes the organiser and teaches the thinking underneath with problems we wrote.

Worked example (ours): one family, two tests

Picture a family in Queens with a first grader and a seventh grader. For the younger child, steps 1 and 2 lead to the NYC Gifted and Talented page. Step 4 settles it: no test. The grades 1 to 4 window opens on April 19, 2027 and eligibility rests on report card grades, so the job is good classroom work and a calm application, not a prep course.

For the older child, step 1 gives two kinds of school. A specialized high school means the SHSAT in grade 8, in fall 2027, under NYC Public Schools. A Catholic high school in the Diocese of Brooklyn/Queens means the TACHS, also in grade 8. Both tests include calculator-light math, so a year of strong middle school math serves both, and the family can decide on registrations a year from now.

What this example shows

The same household met three processes and only two of them were tests. The family read the organisers’ pages first, so nobody spent a winter drilling a six-year-old for an exam that does not exist.

Thinking, not items

What kind of reasoning practice is honest at home?

Puzzles that grow a real habit, and look nothing like a test page. Here are two calendar warm-ups we wrote, one for ages 7 to 9 and one for middle schoolers, with the reasoning written out.

Warm-up 1 (ours, ages 7 to 9)

Question. The 3rd of a month is a Tuesday. What day of the week is the 24th?

Talking it through. A week is 7 days, so every 7 days you land on Tuesday again: the 10th, the 17th and the 24th. Three jumps of 7 is 21, and 3 + 21 = 24. The 24th is a Tuesday. Saying "it repeats every seven" is the rule; check it on a real calendar.

Warm-up 2 (ours, grades 6 to 8)

Question. Today is a Wednesday. What day of the week will it be in 100 days?

Talking it through. Whole weeks change nothing, so only the remainder after dividing by 7 matters. 100 = 14 x 7 + 2, so after 98 days it is Wednesday again, and 2 more days gives Friday. Same idea as warm-up 1, now as division with remainders.

Questions from families

Gifted and selective school tests: common questions

What test is used for gifted and talented programs?

Most US districts use one ability test for screening, usually the CogAT from Riverside Insights or the NNAT3 or OLSAT 8 from Pearson, sometimes with the Iowa Assessments. The score is then weighed with teacher, parent and classroom evidence. Your district's own page names its test.

What is the difference between the CogAT, NNAT and OLSAT?

All three sample reasoning rather than school learning. The CogAT has verbal, quantitative and nonverbal batteries; the NNAT3 is entirely nonverbal, with pictorial directions; the OLSAT 8 covers verbal, nonverbal and quantitative abilities and is untimed up to 75 minutes.

Does NYC have a gifted and talented test?

No. NYC Public Schools decides kindergarten eligibility through pre-K teacher evaluations or interviews, and grades 1 to 4 eligibility through report card grades of 3 or 4 or the equivalent. Its Gifted and Talented page describes no admissions test.

Can you prepare a child for a gifted test?

You can make a child comfortable with the format and grow reasoning through play, but drilling look-alike items is not real preparation. San Ramon Valley Unified recommends no CogAT materials, and Edmonds says excessive NNAT preparation is not recommended.

What grade do children take gifted tests?

Grade 2 is the most common universal screening year, used by San Ramon Valley, Edmonds and Charlotte-Mecklenburg among others. Fort Worth screens grade 1, and Darien screens grades 3 and 5.

Which test do I need for a NYC specialized high school?

The SHSAT, taken in grade 8 or as a first-time ninth grader. NYC Public Schools calls it the sole factor for the eight testing specialized high schools, and it becomes computer-adaptive from fall 2026. LaGuardia High School does not use it.

What is the difference between the HSPT, TACHS, ISEE and SSAT?

The HSPT and TACHS are used by Catholic high schools, with the TACHS in the New York dioceses. The ISEE and SSAT are used by independent day and boarding schools and are now both offered through admission.org. Each covers reading, math and reasoning in its own format.

Is a calculator allowed on these tests?

Not on the SHSAT, the Hunter exam or the HSPT math subtests. The TACHS gives a basic four-function calculator inside its platform from 2026, and personal calculators are not allowed. For the ISEE and SSAT, check the organiser's current rules.

What happened to Duke TIP?

Duke's provost office says TIP and its Academic Talent Search closed permanently in 2020, and Duke's summer work continues through Duke Pre-College. Families now look at programs such as Northwestern's Center for Talent Development.

When are your classes held?

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

Are you connected with any test publisher or school?

No. Modern Age Coders is an independent online school, not linked with Riverside Insights, Pearson, NYC Public Schools, Hunter, Boston Public Schools, STS, the dioceses or E3n. We quote and link their pages, and we cannot promise any score, gifted placement or school place.
