The Written Test

The written test is the half candidates worry about and fail less often. This lesson covers what it asks and, more usefully, how the questions are built.

The format

Multiple choice, with one best answer per question. The number of questions and the pass mark vary by state and by the testing organisation your state contracts with — your candidate handbook has the actual figures, and it is worth reading before test day rather than on it.

An oral version is available in most states, with the questions read aloud, for candidates who read English with difficulty. It has to be requested when you register, not on the day. Some states also offer the test in additional languages. If this applies to you, check the requirement now.

What it covers

The weighting differs by state, and the pattern is consistent enough to plan around. Roughly in order of how many questions they attract:

Physical care skills — the largest share. Personal hygiene, dressing, feeding, elimination, mobility, positioning, measuring and recording. This is the day-to-day work.

Resident rights and ethics — a large and heavily weighted area. Dignity, privacy, choice, refusal, confidentiality, abuse and neglect recognition and reporting, restraint use.

Safety and emergencies — fall prevention, transfer safety, fire and evacuation, choking and emergency response, identifying the resident correctly.

Infection control — handwashing, standard precautions, PPE, isolation, handling soiled items.

Communication — with residents, families and the care team. Observing and reporting. Documentation.

Psychosocial and role — dementia and confusion, cultural and religious needs, end-of-life care, the assistant's place in the team and the limits of the role.

Two of these are worth extra attention relative to how much time programmes spend on them: resident rights and infection control. They carry a lot of questions and the answers follow reliable principles rather than requiring memorisation.

How the questions are built

This is the part that changes your score.

Most wrong answers are not knowledge failures. They are reading failures, and they follow a small number of patterns.

The qualifier is the question

Watch for FIRST, BEST, MOST, EXCEPT, NOT.

When a question asks what you do first, typically two or three of the options are things you should genuinely do. The question is about sequence, and the qualifier is doing all the work. Miss it and you pick a correct action that belongs later.

EXCEPT and NOT invert the whole question. Under time pressure this is remarkably easy to read straight past, and it costs the mark on a question you knew.

Read the last few words of the stem again before looking at the options. That single habit recovers more marks than any amount of extra revision.

Two plausible answers

Standard construction: two obviously wrong options, and two that both look reasonable. The distinction is usually one of:

  • Which comes first
  • Which is within your role, and which belongs to the nurse
  • Which respects the resident's rights, where both are safe
  • Which is safest, where both are permitted

The answer the test wants

Certain principles decide a large number of questions, and they are worth holding as defaults:

Report it. If reporting to the nurse is among the options and something has changed, that is usually the answer. Observing and reporting is the core of the role.

Respect the right. Privacy, dignity, choice, refusal. The right does not stop applying because the care would be beneficial.

Ask the nurse. Anything involving assessment, medication, diagnosis or a change to the care plan is outside your scope, and every option that crosses that boundary is wrong.

Safety first, where safety and preference genuinely conflict.

Explain it to the resident. Telling somebody what you are about to do, before you do it, is almost always part of the correct answer.

Wash your hands. Frequently the first step, frequently the last, and frequently the correct answer to "what do you do before".

What it is not testing

The test is not asking you to diagnose, to decide treatment, or to interpret a clinical picture. Options that invite you to do those things are the wrong ones, and recognising that eliminates a lot of distractors quickly.

Sitting it

Answer every question. There is no penalty for a wrong answer and a blank cannot be right.

Do not linger. Mark the ones you are unsure of, finish the paper, come back. Most candidates have enough time, and the ones who run out spent it on three questions early on.

Your first instinct is usually right. Change an answer when you find a concrete reason in the stem — a qualifier you missed — not because you have stared at it long enough to feel uncertain.

Answer as the textbook, not as your facility. Real workplaces have shortcuts and local habits. The test marks the standard, and where your placement does something differently, the standard is what is scored.

Revising for it

Use your programme's material as the base. The test is drawn from the approved curriculum, and your textbook maps to it more closely than anything online.

Do practice questions and read the explanations for the ones you got right. Getting a question right for the wrong reason is invisible unless you check.

Learn the principles rather than the cases. The test cannot ask about every situation, so it asks about applications of the same handful of principles — rights, reporting, scope, infection control, safety. Learn those and unfamiliar scenarios become answerable.

Learn the normal ranges for the vital signs, since a few questions reliably depend on recognising an abnormal figure. Lesson nine covers these as exam content.

The skills test is next, and it is where the marks are actually lost.

Key things to remember

  • The written test is multiple choice and weighted towards care skills and resident rights
  • An oral version is available in most states but must be requested when you register
  • Most wrong answers come from missing a qualifier in the question, not from missing knowledge
  • The correct answer is usually the one that reports, protects dignity or asks the nurse
