Saville Standalone tests are the single-domain cousins of the Swift family. Where Swift bundles three reasoning modes into one adaptive test, Standalone tests dedicate a full session to numerical, verbal, or diagrammatic reasoning. Used when an employer wants a more thorough evaluation of one specific cognitive domain.
~24 questions in 24 minutes. Tables, charts, financial reports — multi-step calculations involving percentages, ratios, weighted averages, and currency conversion. Calculator provided. Heavy on real-world business context.
~30 questions in 24 minutes. True / False / Cannot Say on business and policy passages. The Cannot Say distinctions are subtle — Saville's verbal tests are notable for the precision required between "False" (passage contradicts) and "Cannot Say" (passage doesn't address).
~24 questions in 24 minutes. Process flow diagrams with input symbols transformed by operators — your task is to determine the output or identify the operator. Used for analytical and engineering roles.
Operational-level versions for customer service, admin, and apprenticeship roles. Same format as Analysis variants but with simpler calculations and shorter passages.
For technical and engineering roles. Mechanical tests cover levers, pulleys, gears, springs. Spatial tests cover 2D-to-3D rotation, mental folding, and spatial pattern recognition.

|---|---|---|
| Format | Fixed (non-adaptive) | Adaptive |
| Duration | 24 min per domain | ~25 min total (combined) |
| Skip allowed | Yes, return to skipped items | No, sequential |
| Best for | Deep evaluation of one domain | Fast triangulation across domains |
Sten scores and percentiles relative to a norm group (graduate, professional, etc.). Cutoffs vary by employer and role. Saville's reports include sub-scale breakdowns — for numerical, you might see sub-scores for "data interpretation" vs "calculation accuracy" vs "speed."
Domain-specific deep work. Unlike Swift where you balance three modes, Standalone tests reward focused preparation in one domain. If you have Numerical Analysis, drill numerical hard for two weeks.
Use the skip-and-return feature. Standalone tests typically allow flagging items and returning later. Don't dwell — flag anything taking over 90 seconds and come back.
Sub-scale awareness. Saville reports include sub-scale scores. If your weak area is "calculation accuracy" rather than "data interpretation," you can target practice on the right component.

Try a free solve Buy question packagesNumerical reasoning on Standalone tests is almost always table-based: two or three small tables of financial, sales, or operational data, followed by a question that requires a multi-step calculation and a unit conversion.
Q. A retail chain sells three product lines. Units sold last quarter were 660 (Line A), 1,140 (Line B) and 310 (Line C). Average selling price was £1.00, £1.00 and £1.00 respectively. Total revenue to the nearest £ was:
A) £1,780 B) £1,950 C) £2,048 D) £2,110
A. Sum the units: 660 + 1,140 + 310 = 2,110. Answer: D.
The actual Standalone question adds distractors: prices in pence rather than pounds, mixed currencies, unit ambiguity (per pack vs per item). Candidates who rush the unit check pick C or B despite nailing the arithmetic.
Standard Standalone Verify numerical assessments give 18 questions in 18 minutes — about 60 seconds per question. That sounds generous but each question has 3–5 numbers to read, a calculation (often multi-step), and a unit conversion.
If you're past 75 seconds and still unsure, flag and move on — you can't recover four lost minutes from one stubborn question.
