ADF JOA Numerical

Everyday quantitative reasoning: sequence rules, arithmetic fluency, percentages and ratios, reading tables and graphs, practical word problems, and unit conversion or estimation. It rewards accuracy and speed on familiar operations, not advanced or formula-heavy mathematics, so revision should focus on confident mental calculation and careful reading.

The ADF sets and periodically updates the structure and timing of its assessments, and these details can vary by role and by the stage of your application. Rather than relying on secondhand figures, check the official ADF recruitment website or your candidate portal for the current format before you sit the test.

Assume you cannot. JOA-style numerical tests are generally designed to be completed with mental arithmetic and rough working on paper or a whiteboard. Practise without a calculator so your speed and confidence with multiplication, division, fractions and percentages are built for the conditions you will actually face.

There is no single publicly stated cut-off, because requirements depend on the role you are applying for and are set by the ADF. Your result is used alongside other assessments and interviews to guide role matching. Ask your recruiting officer what standard applies to your preferred roles.

The individual skills are mostly at junior-to-middle secondary level. The difficulty comes from time pressure, multi-step questions and the need to switch between topics quickly. Most candidates find that targeted practice raises their score substantially, because the errors are usually careless ones rather than gaps in knowledge.

Misreading the question, especially with units, percentages and 'which is closest to' wording, and spending too long on one hard sequence while easier questions go unanswered. Build a habit of reading the final line first, estimating the answer before calculating, and abandoning a question after a set time.

Start with mental arithmetic and times tables, then percentages, fractions, ratios and unit conversion, since these underpin everything else. Add table and graph interpretation and word problems next. Leave number series until last, as sequence rules improve fastest once your basic computation is reliable.

Retake rules depend on the assessment stage, the role and how much time has passed, and they are applied by the ADF rather than by any practice provider. Speak to your recruiting officer about your options and any waiting period before assuming you can sit it again straight away.

Use them sparingly and diagnostically. Do one untimed set to find weak topics, work on those topics, then take timed mixed sets to build pacing. After each set, write down why every wrong answer was wrong; the pattern in those notes is the most useful revision material you will produce.
