- Harver's Cognitive Ability Assessment includes five possible subtests: Logical Reasoning, Verbal Reasoning, Perceptual Speed and Accuracy, Numerical Reasoning...
- Your invitation email - not a universal syllabus - determines which subtests you'll actually see.
- Scores sit on a norm-referenced scale where 50 is average and most candidates fall between 30 and 70.
- HA is a pre-employment assessment, not a certification, so there's no renewal cycle or credential to maintain.
HA Overview: The One-Minute Version
If you've been invited to take the Harver Assessment (HA) and need the facts fast, this page is built to be scanned, not studied line by line. It condenses everything covered in the longer HA Study Guide 2026: How to Pass on Your First Attempt into a single reference you can reread the night before your test.
Harver's Cognitive Ability Assessment is a configurable battery. Employers choose which subtests to assign, and they can layer in personality inventories, situational-judgement scenarios, game-based exercises, or job-specific modules on top of the cognitive portion. That means two candidates applying to two different companies - or even two different roles at the same company - may see completely different combinations. There's no single fixed exam, which is why generic "HA prep" advice floating around the internet is often misleading.
The Five Domains at a Glance
Harver lists five cognitive subtests that can appear in an assessment invitation. Employers can assign one, several, or all five depending on the role they're hiring for. Understanding the full list helps you anticipate what's coming, even before you know your specific battery.
| Domain | What It Measures | Typical Question Style |
|---|---|---|
| Logical Reasoning | Pattern recognition, sequences, deductive rules | Abstract shape or symbol sequences |
| Verbal Reasoning | Reading comprehension and language-based logic | Short passages with true/false/cannot-say statements |
| Perceptual Speed and Accuracy | Fast, accurate visual comparison | Matching pairs of codes, symbols, or data under time pressure |
| Numerical Reasoning | Working with figures, ratios, and data tables | Charts, percentages, and basic arithmetic reasoning |
| Spatial Ability | Mental rotation and visualizing 3D relationships | Folding, rotating, or assembling shapes |

Scoring: What the Norm-Referenced Scale Actually Means
Harver reports cognitive results on a norm-referenced scale where 50 represents the average score and most candidates land somewhere between 30 and 70. This is fundamentally different from a percentage-correct or pass/fail exam. You're not being measured against a fixed cutoff - you're being measured against the pool of people who've taken the same subtest.
Because employer benchmarks are role-specific, there's no universal "good score" for HA. A logistics role prioritizing Perceptual Speed and Accuracy might set a very different bar than an analyst role weighting Numerical Reasoning heavily. If you want the full breakdown of how these thresholds work in practice, the HA Passing Score 2026: Exactly What You Need to Pass article walks through it in detail.
Key Takeaway
Don't chase a mythical "passing number." Focus on performing consistently across whichever subtests your invitation actually includes - that's what the employer's benchmark is built around.
Format, Invitations, and Battery Combinations
HA is administered online and is always employer-invited - you won't find a public sign-up page or open testing window. Your invitation email is the actual source of truth for what you'll face: it specifies which cognitive subtests are included and whether personality, situational-judgement, or game-based modules are bundled alongside them.
- Testing happens remotely, typically from a personal computer, on a timeline set by the employer.
- Subtests can be combined in almost any order depending on the role.
- Because this is a pre-employment tool rather than a certification, there's no exam fee charged to candidates, no recertification, and no scheduling body to coordinate with beyond the hiring company itself.

And if you're wondering whether any costs are involved on your end, the HA Certification Cost 2026: Complete Pricing Breakdown page clarifies what's employer-funded versus candidate-funded.
Domain-by-Domain Cheat Sheet
Below is the fastest way to refresh each subtest right before your test window opens.
Logical Reasoning
Expect abstract sequences of shapes or symbols where you identify the next item or the rule connecting them. There's no vocabulary or math knowledge required - just pattern tracking under time pressure.
- Scan for rotation, shading, and count changes across each item in a sequence
- Eliminate obviously wrong answers first to save time
Verbal Reasoning
Short passages are followed by statements you mark as true, false, or "cannot say" based strictly on the text - not outside knowledge or assumptions.
- Read the passage once fully before answering
- Watch for statements that sound plausible but aren't actually supported by the text
Perceptual Speed and Accuracy
This subtest is less about reasoning and more about sustained visual attention - matching codes, symbols, or short data strings quickly and correctly.
- Practice scanning left-to-right without skipping characters
- Accuracy matters as much as speed, so don't rush past obvious mismatches
Numerical Reasoning
Questions typically involve tables, charts, ratios, and percentages requiring you to interpret data rather than perform complex calculations.
- Refresh percentage, ratio, and basic proportion calculations
- Practice reading data tables quickly to extract only the numbers you need
Spatial Ability
These items test mental rotation and 3D visualization - folding flat shapes into solids, or picturing how an object looks from another angle.
- Practice visualizing rotations without physically turning your screen or paper
- Work through folding/unfolding shape puzzles to build intuition
A Compressed Prep Schedule
If your invitation gives you only a short runway, prioritize by likelihood and personal weakness rather than trying to master all five domains equally. A compressed version of the fuller plan in the HA Study Guide 2026: How to Pass on Your First Attempt looks like this:
Diagnose and prioritize
- Take one practice item from each of the five domains on ../ to identify your weakest two
- Confirm which subtests your specific invitation actually includes
Drill your weak domains
- Spend focused blocks on Logical Reasoning or Spatial Ability if either was shaky
- Use short, timed sets rather than long untimed sessions
Speed and accuracy under pressure
- Run timed Perceptual Speed and Accuracy drills daily - this domain improves fastest with repetition
- Mix in Numerical Reasoning data-table practice
Light review, no cramming
- Skim this cheat sheet and the domains guide once
- Rest - fatigue hurts Perceptual Speed and Accuracy scores more than any other subtest
Common Misreads to Avoid
- Assuming a fixed exam: HA's battery changes by employer and role, so studying only one domain because "that's what HA tests" is a common and costly mistake.
- Treating the score like a percentage: A score of 55 isn't "55% correct" - it reflects standing relative to other test-takers on a scale centered at 50.
- Ignoring Perceptual Speed and Accuracy: Candidates often over-prepare for reasoning domains and neglect this subtest, even though it can carry real weight for operations and logistics roles.
- Confusing HA with a certification: There's no credential, license, or renewal tied to this assessment - it's strictly a hiring-stage evaluation.

Frequently Asked Questions
No. Harver's Cognitive Ability Assessment is a pre-employment screening tool used during hiring, not a credential with ongoing validity or renewal requirements.
Not necessarily. Employers can assign one or multiple of the five subtests - Logical Reasoning, Verbal Reasoning, Perceptual Speed and Accuracy, Numerical Reasoning, and Spatial Ability - and combine them with other modules based on the role.
Scores are norm-referenced, with 50 as average and most results between 30 and 70. There's no universal "good" number since employer benchmarks are role-specific.
Your invitation email from the employer specifies the exact battery, including which cognitive subtests and any additional personality, situational-judgement, or game-based modules are included.
Confirm your specific subtests from the invitation first, then prioritize practice on your weakest one or two domains rather than spreading effort evenly across all five.
