Head of Evidence & Improvement

We are recruiting for a Head of Evidence & Improvement
About the mission

Nesta’s A Fairer Start mission aims to ensure that every child has a fair chance of developing to their full potential in the early years. Our portfolio of work spans parenting support, financial support, integrated early years systems, and high quality early childhood education and care. We bridge practical, on-the-ground improvements with long-term policy development and reform. 

As part of our A Fairer Start mission, Nesta is seeking to incubate an ambitious cross-sector initiative focused on improving the quality, evidence base, and real-world impact of parenting and home learning environment programmes in the early years.

Hosted by Nesta,we aim to bring together programme developers, local authorities, practitioners, and evaluators to bridge the gap between research and frontline practice across three core pillars:

• Programme development: Supporting developers to design, adapt, and iteratively improve early years programmes through test-and-learn approaches—ensuring interventions are engaging for families, feasible for teams to deliver, and built for measurable impact.
• Evaluation: Commissioning robust, UK-based evidence on what works, for whom, and in what contexts through rigorous feasibility, implementation, and impact evaluations.
• Evidence into practice: Translating findings into practical tools, guidance, and actionable insights that help commissioners and practitioners use the best available evidence to shape services.

• Technical oversight and quality assurance: Provide senior technical oversight across the portfolio, including stage-gate decisions, quality assurance of evaluation designs and findings, and judgements on the strength of evidence.
• Budget and resource management: Support the EIP’s Director with planning the EIP’s budget and resourcing. Oversee substantial budgets, ensuring resources are allocated effectively across the portfolio.
