Why this program matters

  • Without accessible vocalizable error messages, 20% of users with disabilities—or 1 in 5 people—abandon your interfaces, generating 65% of UX complaints tied to digital inclusion.

  • Each incident costs an average of 8,000 € in extended customer support, emergency redesigns, and lost conversions, tripling lost hours for dev teams.

  • Your company faces RGAA fines of up to 25,000 € and a tarnished reputation, jeopardizing projects and careers against inclusive competitors.

  • Every month without control accumulates these risks, irreversibly stalling growth.

Our method

How Learni guarantees the quality of your Vocalizable Accessible Error Messages training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
