Supporting features
A multi-perspective approach to performance you can act on
From goal-setting and progress tracking to peer feedback and talent calibration, every stage of the performance management cycle is anchored in documented evidence. Ratings are consistent, decisions are explainable, and nothing is left to guesswork.
Reviews and objectives
Generic reviews don't reflect real goals or risks. Our platform delivers structured goal tracking, AI-assisted drafting, and psychosocial risk flagging to make every performance dialogue meaningful and every evaluation explainable.
360° feedback
Collecting feedback from just one source can skew important decisions. Assessio combines self, manager, and peer input into one fair, complete evaluation, with insights that reflect the full picture.
People review
Succession planning shouldn't live in a spreadsheet, disconnected from what happens next. Assessio structures talent calibration and tracks action plans, so decisions lead to real follow-through.

"These reviews now spark reflection and meaningful dialogue that go far beyond operational performance."
Victoire Pellegrin
Talent Development Director, France & International HR Projects, JCDecaux
"For our 600 employees and managers, the talent review is a well-embedded, well-understood process, and a key part of how we develop people."
Sophie Bourrut Lacouture
Labeyrie Fine Foods
"Reviews are now seen as genuine management tools, with real added value for our development and engagement strategy."
Barbara Klein
Audika
"We put direct managers, not distant department heads, in charge of positioning their people, which brought real objectivity to our talent reviews."
Stève Noël
HR Director, Rabot Dutilleul
"When we introduced the test tools as an optional part of our annual review, we were curious how many would use them. It turned out to be close to 100%, and both managers and employees experience clearly more value and more focused review conversations."

Browse our FAQS to find out more.
Can Assessio show me who’s ready for their next role?
Yes. By combining performance outcomes with each person’s Talent Profile, Assessio surfaces who is exceeding their current role and ready to progress, and flags the specific competencies to develop first.
How does Assessio connect hiring data to performance data?
Every hire starts with a Talent Profile built from validated assessment data. As performance, engagement, and feedback accumulate, that profile grows richer, so you can see which hiring signals actually predicted success and refine your criteria accordingly.
Does Assessio replace our existing performance review process?
Assessio can run your full review cycle — goals, check-ins, ratings, and calibration — or layer validated data on top of your existing process, whichever fits your organisation.
How does Assessio help identify underperformance risk early?
Assessio’s AI agent, SIO, continuously synthesises performance and engagement signals to flag emerging risk — whether that’s disengagement, stalled progress, or a mismatch between role and strengths — so managers can act before it becomes a bigger problem.
