To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Participants discover the fundamentals of assertiveness through concrete role-plays. They explore the differences between passivity, aggressiveness, and assertiveness using company examples. Reformulation and feedback exercises are carried out in pairs to anchor the first reflexes.
The day focuses on the clear expression of needs in technical environments. Learners practice formulating requirements during code reviews and team meetings. Real cases from Django and Flask projects are analyzed to strengthen the impact of messages.
Trainees simulate disagreement situations on FastAPI architectures. They learn to defend their technical choices while remaining constructive. Each exercise results in a written and oral deliverable that will be evaluated collectively.
Focus on assertive feedback in sprints and retrospectives. Participants design conversation frameworks adapted to Python developers and test them through role-play. Emphasis is placed on emotional regulation and professional posture.
The final day enables the construction of a personal action plan and the presentation of an assertive project to the group. Learners finalize their training deliverable and receive an individual diagnosis to anchor the acquired skills in their daily practice.
The Training Assertiveness 2026 - Developing Professional Skills program is delivered onsite or remote (blended-learning, virtual classroom, remote presence).

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
