Is Your Child Ready for Northwestern CTD? What Illinois Parents Need to Know About Gifted Math Programs

If you have a mathematically gifted child in the Chicago suburbs, you may have heard other parents mention Northwestern CTD — and wondered whether it might be right for your kid. You may also have heard terms like NUMATS, above-level testing, or talent search and not been entirely sure what they mean or how they connect.

This post explains the landscape clearly: what Northwestern CTD is, how its assessment program works, and what you can do right now to help your child put their best foot forward.

What Is Northwestern CTD?

The Center for Talent Development (CTD) at Northwestern University in Evanston is one of the most respected gifted education programs in the country. Founded in 1982, CTD has spent more than four decades developing research-backed programs for academically advanced students from preschool through grade 12.

CTD's core mission is identifying students whose abilities exceed what standard grade-level testing can measure — and connecting them with learning experiences that actually challenge them. Its programs include online courses, weekend enrichment sessions, summer residential camps on Northwestern's Evanston campus, and the above-level assessment program formerly known as NUMATS.

What Is CTD Assessment (Formerly NUMATS)?

NUMATS — the Northwestern University Midwest Academic Talent Search — was the original name for CTD's above-level testing program. It is now officially called CTD Assessment, but many families and educators still use both names interchangeably.

Here's the core idea: standard grade-level tests have a ceiling. A student in 5th grade who is performing at a 10th-grade level will max out a 5th-grade test, and you won't learn much from the score. CTD Assessment solves this by having younger students take tests designed for much older students — typically the PSAT 8/9 for grades 3–6, and the SAT or ACT for grades 6–9.

This "above-level testing" approach reveals where a student's abilities actually sit, not just whether they've cleared the grade-level bar. The results inform which CTD courses and programs a student is ready for, and they serve as a meaningful benchmark for academic planning going forward.

Students qualify to participate in CTD Assessment if they score at or above the 90th percentile on a nationally normed achievement test — which includes state standardized assessments, the PSAT, or other recognized tests. If your child is in a gifted or advanced academic program at school, they likely qualify.

What Programs Does CTD Offer?

Once a student has participated in CTD Assessment, they become eligible for CTD's range of programs, which include:

Online enrichment and accelerated courses — covering math, science, writing, and humanities for grades 3 through 12. These are asynchronous and flexible, designed to fit around school schedules.

Weekend Encounters programs — half-day in-person sessions at local partner schools that give students an immersive, deep-dive experience in a specific topic.

Summer Academic Camps at Northwestern — three-week residential or day programs on the Evanston campus for students in grades 5 through 12. These are the most coveted offering and students from across the country attend. The math and science offerings are particularly strong.

Family Academic Programs — for younger students (grades K–3) and their parents, designed to identify emerging strengths and build a foundation for future enrichment.

Why This Matters More Than Most Parents Realize

Here's something that surprises many families: Illinois public schools are not required to provide gifted services in the same way that special education services are mandated. There is growing pressure at the state level to improve gifted programming — and new state policies around accelerated placement are helping — but access varies dramatically by district.

The practical implication is that many mathematically advanced students in the Chicago suburbs are spending years in classrooms where the pace is too slow and the ceiling is too low. They may be getting straight A's and appearing fine. But their mathematical development is stalling.

CTD Assessment and CTD programs exist precisely for this gap. They provide an honest measurement of ability and access to learning that is calibrated to where a student actually is, not where their grade suggests they should be.

The Competition Connection

CTD participation often goes hand in hand with math competition involvement — and Illinois has a rich competition ecosystem for gifted students. The major milestones for families in the Round Lake Beach area include:

Illinois Mathematics League (IML) — in-school competitions for grades 4 through 12, typically organized through schools. A strong starting point for students just beginning competition math.

MATHCOUNTS — the most prestigious middle school math competition in the country, with a chapter-level competition in the Chicago suburbs, a state competition in March, and a national championship. Illinois has historically produced strong competitors.

AMC 8 and AMC 10/12 — the American Mathematics Competition series, which is the entry point to the most prestigious high school competition ladder in the US (AMC → AIME → USAMO → International Mathematical Olympiad). The AMC 8 is for students in 8th grade and below; the AMC 10/12 for high schoolers.

Illinois Middle School Math Olympiad (IMSMO) — a newer in-state competition that selects participants based on MATHCOUNTS and AMC performance.

MOEMS (Math Olympiads for Elementary and Middle Schools) — a highly popular national competition split into Division E (grades 4–6) and Division M (grades 6–8). Rather than a single high-stakes exam, it consists of five monthly mini-contests from November to March. It’s an incredible tool for building stamina and teaching kids how to tackle non-routine, "out-of-the-box" logic problems.

ICTM State Math Contest (Illinois Council of Teachers of Mathematics) — a massive staple in Illinois schools. For elementary and middle schoolers (grades 3–8), the ICTM Grade School Contest features both individual and team rounds, culminating in an exciting way to represent their school at the state level. They also host a rigorous Algebra contest for advanced junior high students.

CTD's above-level testing is closely connected to competition readiness: students who perform well in CTD Assessment tend to be the same students who are ready to begin serious competition math preparation.

How Mathnasium Helps

At Mathnasium of Round Lake Beach, we work with families navigating all of this — from parents who are just beginning to realize their child needs more challenge, all the way to students preparing for CTD summer programs or MATHCOUNTS state competition.

Our approach starts with a free assessment that gives you an honest, specific picture of where your child is mathematically: their strengths, any gaps in their foundation, and what it would realistically take to prepare for the next level — whether that's CTD Assessment, a specific competition, or simply getting ahead of the curve.

For students who qualify for CTD programs or competition math, we build a targeted plan. For students who aren't there yet but have the potential, we build the foundation that gets them ready.

When to Start

Ideally, 3–6 months before any specific program deadline. CTD Assessment has registration windows throughout the year. MATHCOUNTS chapter competitions run in February, with preparation typically beginning in the fall. The AMC 8 is held in January.

That said, it's never too early to begin building mathematical depth and confidence. If your child is in 3rd or 4th grade and showing strong mathematical aptitude, foundational work now pays compounding dividends.

Not Sure If Your Child Is Ready?

We offer a free math skills assessment at Mathnasium of Round Lake Beach — no obligation, no pressure. It takes about an hour and gives you a clear, specific picture of your child's mathematical strengths and where targeted preparation would make the biggest difference.

Whether your child ends up pursuing CTD programs, competition math, or simply needs more challenge than school is currently providing, understanding where they actually stand is always the right first step.
