NNAT3 Level F key terms

The ability to identify the missing piece that finishes a design or sequence so that its rules and symmetry stay consistent. On the NNAT3 it appears as a large matrix with one empty cell to fill from answer choices.

A relationship shown between two items that must be applied to a third item to find its partner. The candidate must name the rule linking the first pair, such as size change or rotation, before choosing an answer.

Finding the rule that governs a left-to-right or top-to-bottom progression of figures and using it to predict the next or missing member. Rules may involve adding elements, rotating, or alternating two features.

Mentally assembling, folding, rotating, or reflecting shapes to decide how they look after a transformation. Items often show pieces that combine into one figure or a folded paper that is unfolded.

Solving a grid of figures in which rows and columns follow consistent rules, then selecting the option that completes the grid. It is the main format of the NNAT3 pattern completion items.

The consistent relationship or transformation that links figures in an item, such as doubling the number of sides or shifting a shape one position. Identifying the rule is the core step in every nonverbal reasoning question.

A sequence in which a feature changes by a steady step, for example shapes gaining one side each time or dots moving clockwise. The candidate uses the step size to predict the missing figure.

A pattern in which two or more features take turns, such as a filled shape, then an outline, then filled again. Recognizing alternation prevents choosing a figure that fits only half the sequence.

Imagining how a figure looks after being turned by a given angle without changing its shape or size. Distractors often show the correct shape rotated wrongly or mirrored instead of turned.

A mirror image of a figure across a vertical, horizontal, or diagonal line. Reflected figures keep their size but reverse orientation, which distinguishes them from rotated copies.

A property of a figure that looks unchanged when folded or turned along a line or around a point. Symmetry helps predict missing parts of a design and rules out answer choices that break the balance.

The direction a figure faces, described by rotation angle or by which side points up. Two figures can be identical in shape yet differ in orientation, a common source of wrong answers.

Turning a figure around a fixed point by a set number of degrees, such as a quarter turn clockwise. Tracking rotation across a series is a frequent rule in serial reasoning items.

Any change applied to a figure, including sliding, turning, flipping, resizing, or shading. Naming the transformation type helps the candidate match the rule used in the example.

Sliding a figure to a new position without turning, flipping, or resizing it. In matrices, translation rules move a shape across cells while keeping its appearance identical.

A spatial task in which a sheet is folded, holes are punched, and the candidate predicts the hole pattern after unfolding. Correct answers respect the fold lines and mirror each punch across them.

Combining separate pieces mentally to form a complete shape, or deciding which pieces could form a given outline. Edges and angles must match without gaps or overlaps.

An answer choice designed to look plausible but that breaks the rule in a small way, such as wrong shading, extra elements, or a mirrored shape. Comparing each option against the rule eliminates distractors.

A measurable feature of a figure such as color, size, number of sides, fill, or position. Rules are usually built from one or two changing attributes while the others stay constant.

Solving problems using shapes, patterns, and spatial relationships rather than words or numbers. The NNAT3 measures this ability because it reduces dependence on language and school instruction.

The capacity to detect underlying rules in unfamiliar visual material and apply them to new cases. It supports pattern completion, analogy, and serial reasoning tasks on the test.

The mental workspace that briefly holds visual details while a rule is tested against answer choices. Strong working memory helps a candidate track several changing features at once.

How quickly a candidate can compare figures and choose an answer under timed conditions. On the NNAT3 it matters mainly for finishing comfortably rather than for solving hard items.

Managing time across test sections so every item receives attention without rushing early questions. A steady pace with brief checks on hard items usually protects the total score.

Nervousness before or during testing that can cloud attention and slow decision making. Calm routines, familiar practice formats, and adequate sleep help reduce its effect on performance.

Score improvement that comes from familiarity with item formats and test routines rather than from a real change in ability. Some practice is useful, but heavy drilling can inflate scores and reduce the test's meaning.

A planned approach such as reading directions carefully, eliminating wrong options, and marking uncertain items to revisit. Consistent strategies help candidates use their reasoning ability more reliably.

A rule for handling items the candidate cannot solve, usually answering every question because there is no penalty for wrong answers. Eliminating one or two options first improves the odds.

Administering a test with the same directions, timing, and conditions for every candidate so scores are comparable. Standard conditions protect fairness and make norm comparisons meaningful.

The reference sample whose scores are used to convert a raw score into a percentile or standard score. Norms describe how a candidate compares with peers of similar age or grade.

The percentage of the norm group scoring at or below a given score. A percentile of 75 means the candidate performed as well as or better than 75 percent of the comparison group.

A converted score that places a result on a fixed scale with a known average and spread, making comparisons across ages easier. It is not the same as the raw number of correct answers.

The consistency of a test's scores across forms, occasions, or raters. High reliability means similar performance would likely produce similar scores, though it does not by itself prove validity.

The degree to which a test measures what it claims to measure and supports the inferences made from scores. A test can be reliable yet still weak for a particular purpose.

An approved change to testing conditions, such as extra time or a separate room, that removes a barrier without altering what the test measures. Accommodations must be arranged in advance under local policy.

The simple count of items answered correctly before any conversion. Raw scores are turned into standard scores or percentiles using norms before they are interpreted.

The process of screening students for gifted or advanced programs using multiple sources, often including reasoning tests, teacher input, and achievement records. No single score should decide placement alone.

Using several independent measures, such as test scores, portfolios, and classroom performance, when making placement decisions. This approach reduces the chance that one imperfect measure decides a student's path.

Explaining what a score means in context, including its confidence interval, comparison group, and limits. Scores describe one sample of performance and should not be treated as fixed labels.

A range around an observed score that likely contains the candidate's true score, accounting for measurement error. Ranges remind users that small score differences may not be meaningful.
