32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Contrapositive

The logically equivalent form of 'if P then Q', namely 'if not Q then not P'. Unlike the converse, it always preserves the truth of the original statement.

Percentage points

The arithmetic difference between two percentages. A change from 20% to 25% is five percentage points, which is a 25% relative increase.

Reverse percentage

Recovering an original value after a known percentage change. Divide the final value by one plus or minus the rate, for example 92 divided by 1.15.

Validity before merits

The principle that an application must first satisfy formal requirements such as correct form, fee, identity evidence and deadline before the substance of the case is assessed.

Visa versus leave

A visa permits travel to a border but does not guarantee admission. Leave to enter or remain is the status granted by a decision, often made on arrival.

Deception finding

A formal conclusion that an applicant used false representation or omitted material facts. It is serious and can lead to refusal and re-entry bans.

Affirming the consequent

A fallacy that reasons 'if P then Q; Q is true; therefore P'. The conclusion does not follow, because other causes could also produce Q.

Some versus all

A logical distinction. Premises containing 'some' cannot support an 'all' conclusion, so any answer generalising beyond the stated quantity is invalid.

Scope words

Quantifiers such as all, some, only, never and primarily. They determine whether a reading-comprehension option is stronger or weaker than the passage supports.

Inference versus assumption

An inference follows necessarily from stated evidence. An assumption is unstated and needed for an argument to work, so an option requiring one is not supported.

Author tone

The attitude revealed by evaluative vocabulary rather than subject matter. Neutral reporting, advocacy and criticism are distinguished by adjectives and verbs used.

Combined work rate

When two workers or systems act together, their rates add. Total time equals one divided by the sum of the individual reciprocal times.

Misleading axis

A chart whose vertical axis does not start at zero, visually exaggerating differences between values. Check scale and units before interpreting.

Conflict of interest

A personal or financial interest that could bias a decision. The required response is disclosure and withdrawal from the case, not private self-assessment.

Gifts and hospitality

Offers that could influence official decisions. They are declined and reported even when small, because the appearance of influence damages public trust.

Confidentiality principle

Case information is shared only with people who need it for a lawful purpose. Discussing cases outside secure, authorised settings breaches that duty.

Record integrity

The duty to keep official records accurate and unaltered. Backdating, amending or omitting entries to conceal a mistake is misconduct and must be reported.

Escalation rule

When a decision exceeds your delegated authority, refer it upward rather than acting informally. Escalation is documented and stays within lawful limits.

Proportionate response

The chosen action matches the seriousness of the issue, resolves it lawfully, and is recorded. Inaction, concealment and retaliation are always the worst options.

Immediate priorities

In situational judgement, rank safety and security first, then legal compliance, then fairness to the applicant, then administrative efficiency.

Report structure

A standard official report moves through purpose, background, evidence considered, findings, decision or recommendation, and next steps under separate headings.

Attribution of evidence

Clear separation in writing between what the applicant stated, what a document shows, and what the officer concluded from it.

Active voice

A sentence construction naming the actor, such as 'the officer refused the application'. It prevents ambiguity about who made a decision and why.

Homoglyph check

Scanning identifiers for look-alike characters such as zero and letter O, one and letter l, five and S, which cause transcription errors.

Date logic check

Verifying ordering relationships: issue before expiry, travel within validity, application before deadline, and age computed at the legally relevant date.

Independent recomputation

Checking arithmetic by a different route, for example verifying a total by subtraction, rather than rereading the same figures and repeating the error.

Cross-document consistency

Confirming that name order, transliteration, passport number and date of birth match identically across every document in the case file.

Negation shift

A construction where negatives cancel or intensify, such as 'not uncommon' meaning 'common'. Restate positively before choosing an answer.

Syllogism chain

A deductive form linking categories, where 'all A are B' and 'all B are C' entail 'all A are C'. Quantity words must stay consistent.

Standard of proof

The level of certainty a decision-maker must reach, which varies by application type. Apply the standard specified for that route, not a default.

Continuity of residence

A qualifying period calculated from entry and exit records, counting only permitted absences under the applicable rule for that route.

Decision record

A written account stating the ground for refusal, the rule applied, and why evidence was insufficient, so the decision can withstand appeal or review.
