Inference

A conclusion drawn from evidence in a text rather than stated outright; the reader supplies the link the author leaves implicit, so it must be supported by the passage but not simply repeated from it.

Related: Conclusion, Assumption
Assumption

An unstated belief the author treats as true and relies on to make the argument work; if it fails, the reasoning collapses even though no sentence in the text states it.

Related: Premise, Conclusion
Premise

A stated reason or piece of evidence offered in support of a conclusion; premises are what an argument asks you to accept before it can persuade you of its main claim.

Related: Conclusion, Logical fallacy
Conclusion

The claim an argument is trying to establish; it is what the premises are meant to support, and it may appear at the start, middle or end of a passage.

Related: Premise, Inference
Tone

The attitude an author conveys through word choice and sentence style, such as cautious, critical, ironic or neutral; it shapes meaning beyond the literal content of the sentences.

Related: Ambiguity
Ambiguity

A quality of wording that permits more than one reasonable reading; in reasoning tests, ambiguity often explains why a statement cannot be judged true or false with confidence.

Related: Paraphrase, Inference
Paraphrase

A restatement of a passage's meaning in different words; a correct paraphrase preserves the original's claims and scope without adding or dropping qualifications.

Related: Ambiguity, Inference
Logical fallacy

A pattern of reasoning that appears persuasive but does not actually support its conclusion, such as attacking a person instead of their argument or generalising from a tiny sample.

Related: Premise, Assumption
Percentage change

The difference between two values divided by the original value, expressed per hundred; always divide by the starting figure, not the later one, or the result is wrong.

Related: Index number, Compound growth
Ratio

A comparison of two or more quantities showing how many times one contains another; ratios can be scaled up or down without changing the relationship they describe.

Related: Weighted average, Per capita
Weighted average

A mean in which each value counts in proportion to an assigned weight, such as population size; it differs from a simple average when the groups being combined are of unequal size.

Related: Per capita, Ratio
Index number

A value expressed relative to a chosen base period set at 100, used to show change over time; a reading of 120 means a 20 per cent increase since the base.

Related: Percentage change, Compound growth
Per capita

A total divided by the number of people concerned, giving an average per person; it allows fair comparison between countries or regions of very different population sizes.

Related: Weighted average, Ratio
Compound growth

Growth applied repeatedly to a value that already includes earlier increases, so the amount added rises each period; it is not the same as adding a fixed amount each time.

Related: Percentage change, Index number
Rounding

Replacing a number with a nearby simpler one to a stated level of precision; rounding too early in a multi-step calculation can shift the final answer beyond the offered options.

Related: Percentage change
Sequence

An ordered series of figures or symbols in which each item follows a rule from the one before; finding the rule means testing how position, number or shape changes step by step.

Related: Rotation, Matrix
Rotation

A turn of a figure about a fixed point, described by direction and angle; a rotated shape keeps its size and internal proportions but changes its orientation on the page.

Related: Reflection, Sequence
Reflection

A mirror image of a figure across a line, reversing left and right while preserving size and shape; it is not the same as rotation, though the results can look similar.

Related: Rotation
Matrix

A grid of figures arranged in rows and columns where a rule operates along each row and down each column; the missing cell must satisfy both directions at once.

Related: Sequence, Odd one out
Odd one out

A set of items in which all but one share a common property; the task is to identify the defining feature of the majority and the single item that breaks it.

Related: Matrix
Escalation

Referring a problem to a higher level of authority when it exceeds your mandate, carries serious risk, or cannot be resolved with the resources you control.

Related: Accountability, Conflict of interest
Conflict of interest

A situation where a personal, financial or other private interest could improperly influence official judgement; the standard response is to declare it and step back from the decision.

Related: Confidentiality, Accountability
Confidentiality

The duty to keep sensitive information within authorised channels and to share it only with those who need it for a legitimate purpose.

Related: Conflict of interest
Accountability

The obligation to answer for your decisions and their results to those with a legitimate right to ask, including explaining what you did and why you did it.

Related: Escalation, Stakeholder
Stakeholder

Any person, group or institution affected by or able to influence a decision; effective handling means identifying them early and understanding their interests and concerns.

Related: Escalation, Accountability
Subsidiarity

The principle that the EU acts only where the objectives cannot be sufficiently achieved by member states acting alone and can, by reason of scale or effects, be better achieved at Union level.

Related: Proportionality
Proportionality

The principle that EU action must not go beyond what is necessary to achieve the treaty objectives; the means chosen must be suitable and no more burdensome than needed.

Related: Subsidiarity, Impact assessment
Ordinary legislative procedure

The standard EU law-making route in which the European Parliament and the Council adopt legislation jointly, each reading the other's position, working from a Commission proposal.

Related: Trilogue, Qualified majority
Trilogue

An informal negotiation between representatives of Parliament, the Council and the Commission aimed at agreeing a compromise text before formal readings, thereby speeding up the legislative process.

Related: Ordinary legislative procedure
Regulation

An EU legal act binding in its entirety and directly applicable in all member states without national transposition; it contrasts with a directive, which leaves implementation choices to member states.

Related: Directive
Directive

An EU legal act binding as to the result to be achieved while leaving member states to choose the form and methods; it must be transposed into national law by a set deadline.

Related: Regulation
Acquis communautaire

The accumulated body of EU law, rights and obligations, including treaties, legislation and Court judgments, which candidate countries must adopt before joining the Union.

Related: Regulation, Directive
Impact assessment

A structured appraisal of the likely economic, social and environmental effects of a policy proposal, used to justify the chosen option and compare alternatives before adoption.

Related: Proportionality, Subsidiarity
Qualified majority

A voting threshold in the Council requiring a defined share of member states representing a defined share of the EU population, used to decide most internal-market legislation.

Related: Ordinary legislative procedure, Trilogue
Competency framework

A structured list of the behaviours and skills expected in a role, with descriptors of what weak, adequate and strong performance look like, used to design assessments and give feedback.

Related: STAR technique, Constructive feedback
STAR technique

A way of structuring an answer to a behavioural question by describing the Situation, the Task, the Action you took and the Result achieved, keeping the focus on your own contribution.

Related: Competency framework
Delegation

Entrusting a task to someone else together with the authority and information needed to complete it, while retaining responsibility for the outcome.

Related: Accountability
Constructive feedback

Specific, timely information about someone's behaviour and its effect, offered with the aim of improving future performance rather than assigning blame for what has already happened.

Related: Competency framework, Resilience
Resilience

The capacity to keep functioning and recover after setbacks, pressure or criticism, adapting your approach rather than giving up or becoming defensive.

Related: Constructive feedback
