A key priority for the work-based learning (WBL) sector is to work more closely with employers, developing partnerships across the sector in an attempt to improve the quality of provision. This report suggests practical ways of developing such partnerships. With illustrative case studies, it shares the lessons learnt from a small number of projects that explored different approaches to working collaboratively. The appendices include an Employer Handbook, which will be of a useful starting point for others across the sector. This report forms part of a suite of four publications to emerge from the action research projects commissioned by the Learning and Skills Council. Each publication synthesises the strategies tested and gives other providers in the sector clear guidance on how to improve learner outcomes.
