About this exam

The NB TCN Numeracy examination is a multiple-choice numeracy assessment used in New Brunswick's nursing and health-care education pathway, where TCN refers to the Test de compétences numériques. It is designed for candidates preparing to enter practical nursing, nursing, or allied health programs who need to demonstrate that their foundational mathematics is strong enough for safe medication calculation and clinical measurement. The exam samples broadly rather than deeply: number sense and operations, measurement and unit conversion, ratio and proportion with percentages, data interpretation and basic statistics, algebraic reasoning and patterns, geometry and spatial reasoning, and multi-step quantitative problem solving. Most questions are short, calculator-free arithmetic or applied word problems set in health, workplace, and everyday contexts. Because the test rewards fluency and accuracy under mild time pressure rather than advanced mathematics, the strongest preparation is regular short practice: work through conversions and dosage-style proportion problems daily, drill mental arithmetic without a calculator, and review how to read tables, graphs, and averages. Always simulate exam conditions with timed practice sets, and check your errors by category so you can see whether the weakness is conceptual or simply careless. Confirm the current test format, registration process, and any published administrative details directly with the official administering body, since these details change and are not fixed here.

What you'll study

Common questions

About NB TCN Numeracy preparation

What is the format of the NB TCN Numeracy exam?

It is a multiple-choice test covering the seven numeracy domains listed by the administering body. Questions are short, self-contained, and generally require arithmetic or a two-step calculation rather than formal algebra. Confirm the exact number of questions, the time allowed, and whether any aids are permitted with the official administering body before test day.

How difficult is the exam?

The mathematics itself is at a high-school foundational level: fractions, decimals, percentages, unit conversion, ratios, averages, and simple geometry. Difficulty comes from accuracy under time pressure and from word problems that hide the operation you need. Most candidates who prepare consistently find it manageable; those who rely on a calculator habit often struggle.

Can I retake the exam if I do not pass?

Retake rules, waiting periods, and any associated costs are set by the administering body and can change between sessions. Check its official website or your program office for the current policy rather than relying on what other candidates report. If a retake is permitted, use the waiting time to target your weakest domain with timed practice.

How much time should I allow for each question?

The official time limit determines your pace, so confirm it first. As a working habit, aim to answer routine arithmetic items quickly and reserve extra seconds for multi-step word problems. Practise with a timer so you learn to abandon a stuck question, flag it, and return rather than losing several minutes on one item.

In what order should I study the domains?

Start with number sense and operations, since fractions, decimals, and mental arithmetic underpin everything else. Then move to ratio, proportion, and percent, which drive most health-care calculations. Add measurement and unit conversion next, followed by data interpretation, algebra and patterns, geometry, and finally mixed problem-solving sets that combine domains.

What are the most common reasons candidates lose marks?

Careless errors top the list: misreading units, forgetting to convert millilitres to litres, or dropping a decimal place. Others include rushing word problems before identifying what is being asked, misaligning decimal points in manual calculations, and running out of time because one hard question consumed the clock. Reviewing errors by category fixes these faster than doing more questions.

Do I need a calculator?

Many numeracy tests for health programs restrict or prohibit calculators because the goal is to verify independent computation. Check the official rules for your sitting. Either way, practise mental and paper arithmetic daily, including multiplication tables, percentage shortcuts, and converting between fractions, decimals, and percentages without assistance.

How long should I prepare before writing?

Most candidates benefit from four to eight weeks of short, frequent sessions rather than a last-minute cram. Twenty to thirty minutes a day of mixed practice, plus one timed full-length set each week, builds both speed and confidence. If your diagnostic scores are weak in several domains, allow more time and track improvement weekly.

How do I register and what does it cost?

Registration procedures, test centres, identification requirements, and fees are administered by the official body and are updated periodically. The current fee and scheduling options are published there, so consult the official site or your program coordinator directly.
