The programme structure means your organisation benefits straight away—not months later—with coached delivery, phase‑gate reviews, and a clear line of sight from learning to business impact. With the benefit of either levy funding or 95% government grants – free training.

There are many myths around the apprenticeship Levy read our blog to find out more 

Immediate Benefits for Your Business

• Funding that makes sense — Leverage the Apprenticeship Levy or 95% government co‑investment. For non‑levy employers the typical contribution can be as low as a few hundred pounds for a 12‑month programme.
• Immediate business impact — Apprentices deliver real improvement projects using DMAIC with Master Black Belt coaching and phase‑gate reviews. Typical savings can exceed £50,000 per project, with additional quick wins adding incremental ROI.
• Speed to value — A 12‑month programme (plus ~2 months for assessment) with front‑loaded training and immediate on‑the‑job application.
• Designed around your operation — Flexible delivery (virtual, in‑house, open cohorts), diary‑friendly coaching, and structured off‑the‑job learning (~ per week).
• Simple monitoring & visibility — Manager dashboards, regular progress reviews, and formal gate sign‑offs keep projects on scope, on time, and on target.
• Project selection support — Pre‑enrolment scoping to ensure a feasible, high‑value project with clear baselines and stakeholders.

Benefits for the apprentice

• Immediate, practical learning: Training is front-loaded and hands-on; tools are applied straight away (process mapping, data collection, quick experiments), which accelerates results and buy-in.
• Structured delivery (DMAIC): Define, Measure, Analys, Improve, Control keeps work focused and safe, with gate reviews providing timely feedback and approvals.
• 1:1 expert coaching: Monthly sessions with a Master Black Belt for 14 months build technical competence, project momentum, and career direction.
• Protected learning time: 6 hours/week on average (OTJ) covers eLearning, coaching, project work, and stakeholder engagement; logging little-and-often makes it manageable.
• Recognised qualifications: Completion delivers the Level 4 Improvement Practitioner plus Lean Six Sigma Green Belt, with optional modules (e.g., Change Management, H&S).
• Portable, high-value skills: Capability to improve any function/industry—reducing defects, speeding service, and strengthening control through data-driven methods.
• Evidence of impact: A live project quantifies benefits (savings, lead time, quality), creating a portfolio for performance reviews and future roles.
• Leadership & influence: Practice in stakeholder mapping, facilitation, presenting data, and leading teams increases confidence and visibility with sponsors/senior leaders.
• Peer network: Cohort learning enables sharing of templates, ideas, and lessons learned.
• Supported growth at work: Coaching plus employer-guaranteed OTJ time means development happens during paid hours.
