Testlify vs Assessio: A detailed comparison

Testlify and Assessio answer different halves of the same question. Assessio is a Nordic psychometric publisher built around two well-documented instruments, a Big Five personality questionnaire and a short cognitive test. Testlify is a skills-first assessment platform covering role skills, coding, cognitive ability, personality and AI interviews. Choose Assessio for depth on two signals. Choose Testlify when the role needs more.

TL;DR

• Assessio's platform rests on two flagship tests: MAP, a Big Five personality questionnaire, and Matrigma, a 12-minute non-verbal reasoning test. Both come with public product documentation, which is more than most vendors in this category publish.
• Assessio does not publish a price. You will get a quote, so ask early whether it is charged per candidate or per seat, because those two models diverge fast at volume.
• Assessio reports scores on a C-scale of 0 to 10 and states a measurement error of about plus or minus 1 C-score. That number should decide your cutoffs, and hardly any buyer asks for it.
• Testlify covers a wider spread: role-specific skills, coding, software, language and typing tests alongside cognitive and personality assessments, with proctoring built in.
• Neither vendor carries your legal risk. Under New York City's hiring-tool rules and the EU AI Act, the employer answers for how a score gets used.

What is Assessio?

Assessio is a Swedish talent-assessment company that started in 1954 as a psychology research institute and now sells a recruitment and development platform across the Nordics and the Netherlands. Its business is psychometrics: standardized questionnaires and tests, scored against norm groups, used to screen and develop staff.

Ownership matters more here than it usually does. Pollen Street Capital took a majority stake in Assessio in August 2023, and the company has been buying since, adding assessment businesses in Germany and Estonia. A roll-up is not a red flag on its own. It does change two things you should ask about: which products stay on the roadmap, and whether the contract you sign this year is with the entity that supports you in three.

The company is a test publisher first and a software company second. That shows up in the product. The documentation is unusually specific about what each instrument measures and how it is scored, and unusually quiet about the workflow around it.

What does Assessio actually test?

Assessio's catalogue centres on two instruments plus a set of shorter add-ons. MAP measures personality, Matrigma measures general reasoning ability, and everything else in the range (values fit, service and integrity screening, learning agility, self-awareness insights, leadership feedback) sits around that core.

Assessio's MAP documentation puts real numbers on it. MAP is built on the Big Five model, covering five broad traits with five facets each, so 25 dimensions in total. The full version runs 200 items and takes 20 to 40 minutes. A short version, MAP Essence, runs 75 items in about 15 minutes. Results come back as C-scores on a 0 to 10 scale with a mean of 5 and a standard deviation of 2.

Then there is the detail almost no vendor volunteers: Assessio states the measurement error on those C-scores at roughly plus or minus 1. Read that carefully, because it is the most useful sentence in the whole product doc. A candidate scoring 6 and a candidate scoring 5 are, for practical purposes, the same candidate. If your shortlist rule is "everyone above a 6," you are sorting on noise. Set bands, not thresholds.

The Matrigma test documentation is similarly plain. It is a matrix-reasoning test, non-verbal by design so it travels across languages, capped at 12 minutes. An adaptive version uses item response theory to pick harder or easier items as the candidate goes, and reports on the same C-scale as the classic version.

On integrations, Assessio documents connections to Jobylon, ReachMee, SmartRecruiters, Teamtailor and Varbi. That list tells you who the product is built for. Four of those five are Nordic applicant tracking systems. If your stack sits elsewhere, ask what the integration actually looks like before you assume parity.

Testlify vs Assessio: what each covers

The table below compares the two platforms only on dimensions that can be checked against each vendor's published material. Where a vendor documents nothing publicly, it says "Not published" rather than marking an absence, because a blank in a vendor's marketing is not evidence that a capability is missing.

Three rows in the old version of this page marked Assessio absent on capabilities it has never claimed, including GDPR compliance for a company headquartered inside the EU. Those rows are gone. A comparison table that scores a rival on tests it does not sell is not a comparison, it is a straw man, and buyers see through it.

How much does Assessio cost?

Assessio does not publish pricing. There is no public rate card, no per-test price and no self-serve checkout, so every deal runs through a sales conversation and a quote.

That is normal for a psychometric publisher, and it is not automatically worse. It does mean the burden of comparison falls on you. Ask for the price per completed assessment, not per user, and ask what happens in a month when you assess 400 candidates instead of 40. Ask whether MAP and Matrigma are licensed separately. Ask what a report costs if a hiring manager wants one after the fact. Testlify publishes its plans and rates, so you can model your own volume before anyone calls you.

Which platform fits your hiring problem?

Start from the role, not the vendor. The Testlify Multi-Signal Talent Evaluation Model is the frame we use for this: combine several role-relevant signals (assessments, interviews, simulations, references, reviewer feedback) rather than betting the decision on one. The buying question then becomes simple. How many signals does this role actually need, and can the platform produce them?

Assessio fits when the answer is two, and when those two are personality and reasoning. Graduate intakes, high-volume service roles, leadership development, any process where you want a well-normed Big Five profile and a clean cognitive score and you will get the job-specific evidence from the interview. The instruments are old in the good sense: documented, normed, and boring in exactly the way psychometrics should be boring.

Testlify fits when the answer is more than two. A support hire who needs a written-communication sample. A developer who needs a coding test. An analyst who needs a spreadsheet task. A multilingual contact-centre role that needs language screening. Those are role-specific skills, and a Big Five questionnaire cannot stand in for them however good it is. Our library of role-based assessments exists for that gap, alongside cognitive ability testing and behavioural assessments when the role calls for them too.

Consider a 600-person insurer hiring 25 claims handlers a quarter. Personality and reasoning scores will sort the pile, but the thing that predicts a good claims handler is whether they can read a policy document and write a clear refusal letter. That is a work sample, and it belongs in the screen, not in round three.

How well do these tests predict performance?

Better than a resume, worse than the marketing in this category implies. The honest reference point is the 2022 re-analysis by Sackett and colleagues in the Journal of Applied Psychology, which found the field had systematically overcorrected earlier validity estimates for range restriction. The revised figures put structured interviews around .42, general cognitive ability around .31, and broad personality traits such as conscientiousness closer to .19.

Apply that to Assessio's stack without flinching. Matrigma sits in the cognitive band, so about .31. MAP sits in the personality band, lower. Those are respectable numbers, and they are also a ceiling. A .31 correlation is a real edge across many hires and close to useless for predicting any single one, which is exactly why the C-score error band matters so much.

The practical read: use these tests to widen the funnel and remove obviously poor fits, not to rank the final three. And pair them with something job-specific, because a structured interview or a work sample carries more predictive weight than either instrument alone.

Pro tip: before you sign with any assessment vendor, ask for the technical manual, not the brochure. If a publisher cannot hand you the reliability coefficient and the norm group for the test you are about to run on 300 candidates, that is your answer.

Who is accountable when a test screens someone out?

You are. This surprises buyers every time, and it is the part of the decision no vendor comparison covers.

New York City's rules on automated employment decision tools require a bias audit and candidate notice, and the duty sits with the employer using the tool, not the company that built it. The same logic runs through US federal guidance: the EEOC's guidance on employment tests makes the employer responsible for showing a selection procedure is job related.

In Europe the picture is tightening. Recruitment and selection systems fall into the high-risk tier of the EU's AI Act framework, which brings obligations around documentation, human oversight and record-keeping. Separately, Article 22 of the GDPR restricts decisions based solely on automated processing where they produce legal or similarly significant effects, and a rejection at screening qualifies.

None of that argues against testing. It argues for keeping a human in the loop, documenting why each test is in the process, and being able to explain a cutoff to a candidate who asks. Across the teams we work with, the ones who handle this well decided their cutoffs in advance and wrote down the reason. The ones who struggle picked a threshold from a dashboard on a Friday afternoon.

Hire on evidence, not on a hunch

If your next hire needs more than a personality profile and a reasoning score, see what a multi-signal screen looks like on your own roles. Book a demo and bring a live vacancy, or browse the wider assessment tool category first if you are still mapping the market.

Key Takeaways

• Assessio is a publisher, not a platform play. Its value sits in two well-normed instruments rather than breadth of coverage. That means the evaluation question is not "which tool has more features" but "does this role need more than personality and reasoning". For a graduate intake, often no. For a technical or task-heavy role, almost always yes.
• The C-score error band should set your cutoffs. Assessio publishes a measurement error of about plus or minus 1 on a 0 to 10 scale. Scoring candidates into bands rather than ranking them by a single point stops you rejecting people on statistical noise, and it makes the decision far easier to defend later.
• Unpublished pricing shifts work onto you. With no public rate card, you cannot model cost before a sales call. Ask for the per-completed-assessment price and a volume scenario in writing, because per-seat and per-candidate models diverge sharply once you screen hundreds rather than dozens.
• Validity is real but bounded. Revised estimates put cognitive ability near .31 and broad personality traits near .19. Use these tests to widen and clean the funnel, then let a structured interview or a work sample carry the final decision, because neither instrument was built to separate your last three candidates.
• The integration list reveals the target market. Four of the five documented ATS connections are Nordic systems. If your stack is elsewhere, confirm what the integration does before assuming it matches what you have today, since a shallow connector creates manual work that eats the time the tool was bought to save.
• Compliance duties land on the employer. Bias-audit and notice rules, EU AI Act obligations and GDPR Article 22 all attach to the organisation using the score, not the vendor selling it. Decide and document cutoffs before you launch, and keep a human accountable for every rejection.
