Decisions you can prove, built your way
Most online assessment tools are too rigid for complex organisations. Assessio Bloom pairs validated science with deep customisation, so hiring and development decisions are accurate, provable, and shaped around the way you actually work.
Science-backed decisions
Every assessment in our catalogue is based on over 70 years of psychometric research, allowing you to accurately measure and predict job fit, surface true potential, and reduce bias.
Insights across the talent lifecycle
Assessio Bloom connects pre-hire selection data to post-hire development plans, for a continuous view of potential, performance, and growth.
Yours, down to the every detail
Customise branding, workflows, and integrations without compromising security or scientific rigour. Choose from validated scales, or combine them with third-party or proprietary tests.
Fair to everyone, valuable to all
Give every participant, hired or not, a good experience and real insight into themselves, so they walk away feeling valued, understood, and positive about your organisation.
Every person is unique. Your processes should be, too
Shape an approach that fits your organisation and drives tangible results. From high-volume recruitment to leadership assessment, development programmes, and tender-grade compliance, our assessment platform runs in sync with your business.

Gut feel doesn't scale, whether you're hiring hundreds of employees or one executive. Validated cognitive, personality, motivation, and skills assessments deliver side-by-side comparison and decision support, for job fit and true potential at every level.

Talent Development
Insights gained during hiring often disappear post-hire. Assessments for personal development, leadership growth, and learning agility keep that picture alive, giving managers a richer view of progress and employees clearer insights into their strengths.

Assessio's tools are even more valuable with the right expertise behind them. Our psychologists and specialists can work directly with your data, or train your team to do it on their own, so you get the most from every assessment and decision.

Real results from the HR teams who use Assessio every day.
"They developed every selection method for our 5000 x 5000 project, from online pre-screening to work samples and assessment centres. Recruiting 3,750 new employees from more than 50,000 applicants would never have been this efficient or successful without that support, and the methods showed us exactly which candidates would master the path."
Klaus Pfeiffer
Head of International HR, Volkswagen AG
"Since 2007, our assessment tests have been used to select apprentices and students across around 150 locations in Germany. Our recruiters especially value how easy the instrument is to use, and it makes the process more attractive for applicants too."
Siegfried Czock
Bosch Group
"We've worked successfully together for many years, from choosing trainees to international trainee programmes, right up to potential evaluations for our high potentials. We especially value the test quality, the customisation and the in-depth consultancy."

Who is Assessio Bloom made for?
Assessio Bloom is a talent assessment platform designed for complex organisations with specific requirements around branding, workflows, integrations, compliance, or psychometric depth. It's especially well-suited to enterprise, public sector, and professional services buyers who run tenders, hire at volume, operate across multiple countries, or work with procurement and security teams that ask detailed questions.
How is Assessio Bloom different from Assessio Talent Suite?
Assessio Talent Suite is an end-to-end, online assessment platform built for organisations that want a complete, ready-to-use talent solution with multiple connected capabilities. Assessio Bloom is the configured path: the same scientific foundation, but tailored to your brand, workflows, test catalogue, and compliance regime, with validated opt-in AI . Most customers know which fits within minutes of a discovery call, and our team will guide you to the right solution based on your unique needs.
How is AI used in hiring decisions?
The AI tools in Assessio Bloom are completely optional and designed to assist humans, not replace them. They support processes like assessment lens setup, interview structuring, candidate comparison, and report drafting, while any decision is always made by a human. The platform is designed to exceed the requirements of the EU AI Act, with explainable outputs and clear consent flows for candidates.
Can we use our own branding, workflows, and assessments?
You can apply your brand to the entire candidate journey — from visual identity to tone of voice, reports, and emails. Our validated online assessment tools can be combined with third-party platforms or your own proprietary tests. Customer-specific assessments can be built by our team or imported from your existing catalogue.
What integrations does Assessio Bloom support?
Assessio Bloom integrates with leading ATS, HRIS, HRMS, and HCM systems — including ADP, BambooHR, Greenhouse, Heroma, Jobyon, Lumesse, PayFit, Personio, Randstad, SAP SuccessFactors, SmartRecruiters, and Talention. It supports SSO and SCIM foridentity, and exposes open APIs for custom workflows. New integrations are added regularly.
How are your assessments validated?
Every assessment in the Assessio Bloom catalogue is built and maintained by an in-house psychometrics team, with international norms, continuous quality monitoring, and certifications including DNV, COTAN, and DIN 33430. The platform draws on over 70 years of Assessio's work in psychometric science, and we can run customer-specific validity analyses for organisationswith unique populations or roles.
Where is data hosted, and what certifications do you hold?
Assessio Bloom is hosted in Europe with ISO 27001-certified information security management, ISO 9001 quality management, two-factor authentication, GDPR by design, and Cloud Security Alliance STAR Level 1 assurance. Yearly audits and penetration tests are standard. A full list of certifications and security controls is available in our Trust Centre.
Do you support public sector tenders?
Yes. Assessio Bloom is built with tender processes in mind. This includes European hosting, the certifications procurement teams typically require, support for third-party assessments specified in tender documents, multi-language coverage, and a professional services team that can shape both the proposal and the implementation alongside you.
What languages does Assessio Bloom support?
Assessio Bloom is multi-language across the candidate and recruiter experience, with assessments available in many European languages. Specific language coverage depends on the instruments selected — our team can confirm coverage for your markets during a discovery call.
Does Assessio Bloom support different target groups?
Yes. Assessio Talent Suite is built to support a wide range of target groups, from graduate and apprentice intakes to experienced professionals and executive hires. Assessments and workflows can be adapted to different roles, seniority levels, and candidate populations, including support for multiple languages and accessibility needs, so every group is assessed fairly and appropriately.
