Don't let this gap widen

Why this program matters

  • Without expert mastery of Power Query, data teams waste 50% more time on manual ETL, causing critical reporting delays.

  • Transformation errors generate estimated losses of 20 000 € per project from flawed business decisions, according to Gartner.

  • 65% of BI initiatives fail due to lack of query optimization, exposing the company to major competitive risks.

  • In 2024, profiles without advanced M skills are excluded from 70% of senior data job offers.

  • Each quarter without training widens the gap, multiplying opportunity costs by three.

How Power Query skills are assessed

  • Expert quiz on M language and optimizations
  • Evaluation through complex ETL exercises
  • Presentation of the capstone data pipeline

How the Power Query course is taught

  • Training by active expert BI trainer
  • Exercises on real enterprise datasets
  • Custom ETL capstone project
  • Detailed course materials and resources

Power Query training: access and practical arrangements

The Training Power Query - Automating ETL for Complex Data program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Power Query - Automating ETL for Complex Data program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources

Our method

How Learni guarantees the quality of your Power Query 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.

FAQ

Power Query: frequently asked questions

Which tools are used in Power Query training?+
Hands-on work runs on m language, custom functions and performance tuning. Those tools come from the Power Query program itself, delivered on site over 1 day, so participants practise on the stack they will use at work.
What can participants do after Power Query training?+
They can master advanced M language functions for professional transformations, optimize Power Query query performance in enterprise contexts and develop custom and scalable ETL processes for large data volumes. Those are the stated objectives of the Power Query program at Expert level, checked by the end-of-session assessment.
How is Power Query training assessed?+
Assessment relies on expert quiz on M language and optimizations, evaluation through complex ETL exercises and presentation of the capstone data pipeline. Learni issues a completion certificate together with the individual assessment report at the end of the Power Query program, which an L&D team can file as evidence.
How much does Power Query training cost per participant?+
Power Query training costs $1,155 per participant. For an in-company team, the flat rate starts at $2,195 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
