What are the five evaluation criteria?
What scientific foundation is it built on?
Whether the underlying instrument uses continuous traits or categories, whether it is one instrument or several aggregated, and whether peer-reviewed validity evidence exists for the specific claims being made. A platform that combines instruments of uneven quality inherits the weakest one.
Who in the organization does it actually reach?
Which populations the platform is designed for—candidates, executives, teams, or the entire workforce. Most instruments in this category were built for the hiring funnel or the executive tier, which leaves the manager layer and individual contributors uncovered.
How does insight reach a person?
What has to happen for one employee to apply their results, and who has to be present. Delivery that depends on facilitators has a ceiling set by facilitator capacity. Delivery built into the product does not.
What governance and data control does it provide?
Whether HR can control who is assessed, what is visible to whom, and where data flows—and whether a single framework can be enforced organization-wide. Without enforceable standardization, assessments accumulate department by department and no organizational view is possible.
What does the pricing structure actually do at scale?
Not the headline rate—the structure. Per-user-per-month, per-role, per-profile-plus-facilitation, and per-assessment-plus-certification behave very differently as headcount grows or as adoption falls short.
How do the leading platforms score?
Criterion | Predictive Index | Everything DiSC | Cloverleaf | Hogan | We by Paradigm |
|---|---|---|---|---|---|
Scientific foundation | Proprietary 4-drive + cognitive; published validity | 4 categorical styles | 13 aggregated assessments of mixed validity | Big Five (HPI) + derailers; strongest executive validity | WorkPlace Big Five Profile®, 5 supertraits / 23 subtraits, 40+ years of research |
Workforce reach | HR and managers | Teams, per workshop | Teams and managers | Senior leaders | Every employee |
Delivery model | HR-run platform | Facilitator-led session | Daily nudges in Slack/Teams | Certified coach debrief | In-product journeys, conversation guides, team playbooks |
Governance & data | Yes | Event-level | Limited—HR cannot restrict which assessments are used | Yes, via certification | Yes—one instrument, HR-controlled visibility |
Org-level analytics | Yes, on 4 drives | No | Individual and team only | Limited | Yes, on one common instrument |
Pricing structure | Headcount tiers + modules | Per profile + facilitation | Per user per month | Per assessment + certification | Per user per month |
How should you run the evaluation?
Score each vendor 1–5 on each criterion for your population, not in the abstract. Then ask the two questions that most often get skipped: what percentage of employees will see their own results in a usable form, and what the fully loaded cost per engaged employee is. Those two numbers usually decide the outcome.
On pricing figures: we publish pricing structures, not rates. Rates change constantly, vary by deal, and are frequently misreported. Every profile links to the vendor’s own pricing page. Where a vendor does not publish pricing, we say so rather than estimating.
Frequently asked questions
What should I look for in a personality assessment for employees?
A validated, continuous-trait model (the Big Five is the research consensus), a delivery model that reaches employees without a facilitator in the room, HR governance over who is assessed and what is visible, and a pricing structure that doesn’t penalize full adoption.
Traits or types: which is better for workplace use?
Types (DiSC, MBTI-style tools) are memorable and fast to teach. Traits (Big Five) have more resolution, more peer-reviewed support, and aggregate into organizational analytics. For a one-off workshop, types work; for an ongoing program, traits hold up.
How do I know if a personality assessment is valid?
Look for published reliability and validity evidence for the specific instrument and the specific claims being made, not for the model in general. A platform that aggregates several instruments inherits the weakest one.
Should HR control which assessments employees take?
Yes, if you ever want an organization-wide view. Without enforceable standardization, assessments accumulate department by department and the data never aggregates.
What is the biggest reason personality programs fail?
Reach. Most programs touch the top 15% and never reach managers and individual contributors in the flow of work, so the insight fades by month three and is gone by month six.
