How Early Should You Start Preparing for the CogAT?

One of the most common questions parents ask when they find out their child will sit the CogAT is: "How long do we have, and is it enough time?"

The answer depends on what you mean by "preparation". If you mean intensive test drilling, starting earlier doesn't necessarily help — and can actively harm performance by building anxiety. But if you mean building the reasoning habits and question-format familiarity that genuinely improve outcomes, earlier is almost always better — up to a point.

The research case for early, spaced preparation

Cognitive ability as measured by tests like the CogAT is not fixed — it's a measure of current functioning that reflects both innate potential and developed habits of thought. Children who regularly engage in analogical reasoning, pattern recognition, and logical problem-solving develop measurably stronger performance on these assessments over time.

The key word is over time. Cognitive habits develop through spaced repetition — repeated exposure to reasoning challenges spread across weeks and months, not crammed into days. The research behind this is substantial and dates back over a century.

The formal study of spaced practice began with German psychologist Hermann Ebbinghaus in the 1880s, who documented what he called the forgetting curve — the consistent pattern by which newly learned material fades rapidly unless reviewed at increasing intervals. His central finding, replicated many times since, was that distributed practice across time produces dramatically more durable learning than the same amount of study concentrated into a single session. A landmark 1978 study by Landauer and Bjork at UCLA provided compelling experimental evidence that expanding retrieval intervals — starting with short gaps and gradually lengthening them — produces the most robust long-term retention of any practice schedule. A 2014 meta-analysis published in Psychological Science in the Public Interest by Dunlosky and colleagues reviewed 10 common study techniques and rated distributed practice among the highest-utility strategies, describing the effect size as "large" and noting that it applies across subject areas, age groups, and types of learning material.

For CogAT preparation specifically, this means a child who has encountered analogy questions three times a week for eight weeks arrives at the test having consolidated the reasoning patterns into long-term memory — whereas a child who practised intensively for two weeks immediately before the test will be drawing on much more fragile short-term recall. This is why a child who has been casually thinking about word relationships and number patterns for three months will typically outperform a child who has drilled practice papers intensively for two weeks, even if the second child put in more total hours.

The ideal preparation timeline

If you have 12+ weeks (ideal)

This is the preparation window that produces the most consistent results. At 12 weeks out, your child can be introduced to all three battery types gradually, spend time building genuine familiarity with each question format, work on weaker areas without rushing, and arrive at test day feeling confident rather than pressured.

A sustainable routine at this stage is 10–15 minutes of practice three to four days per week. This is short enough to feel manageable for both parent and child, and frequent enough to build genuine cognitive habits.

If you have 6–8 weeks

Still very workable. Start with a week on each battery type to build initial familiarity, then move into mixed practice across all three. Slightly longer sessions (15–20 minutes) four to five days per week will cover the necessary ground without becoming overwhelming.

If you have 3–4 weeks

Focused but achievable. At this point, prioritise the question types your child finds most unfamiliar (usually nonverbal) and ensure they've seen enough examples of each battery type to remove the novelty factor. Short, daily sessions are better than longer, less frequent ones.

If you have less than 2 weeks

At this point, the goal shifts from building skills to building confidence. Introduce each question type so your child isn't seeing them for the first time in the exam room. Keep sessions short and positive. Focus on managing test-day anxiety rather than on improving scores. And remind yourself — and your child — that the test is one data point, not a verdict.

Year-round enrichment vs test-specific preparation

There's a meaningful distinction between preparing specifically for the CogAT and building reasoning skills year-round. Both are valuable, but they serve different purposes.

Test-specific preparation — in the 8–12 weeks before a known test — focuses on CogAT question formats, strategy development, and building familiarity with the exact types of reasoning the test assesses. It has a clear beginning and end.

Year-round enrichment — puzzles, reading, logical games, number challenges, science exploration — builds the underlying cognitive habits that both support test performance and, more importantly, serve a child's development regardless of any specific test. This is the kind of "preparation" that produces the most durable advantage.

The best approach combines both: a foundation of regular enrichment activities throughout the year, with a focused preparation period in the months before the actual assessment.

What does "too early" look like?

Starting formal CogAT practice more than six months before the test has limited incremental benefit over starting three months before — and risks making your child associate reasoning practice with drudgery rather than challenge. The specific question formats of the CogAT are best learned in the months immediately before the test, not a year or more in advance.

What you can do effectively years in advance is build the general reasoning habits that underlie all CogAT performance: reading widely, playing logical games, having pattern-recognition conversations, doing puzzles. These activities don't feel like test preparation, but they're building exactly the cognitive muscles the CogAT tests.

Signs that your child is ready to start formal preparation

• They can sustain focus for 10–15 minutes on a challenging task
• They have enough reading ability to engage with the question formats (for Grade 2+)
• They can tolerate getting some answers wrong without becoming frustrated or shutting down
• The test is within 12 weeks
