Impact Assessment Outlook Journal vol25: Recruitment and retention in Impact Assessment

This 25th edition of the Impact Assessment Outlook Journal brings together a rich mix of voices from across the UK and internationally, colleagues who have generously shared their experiences, strategies and personal reflections.

We cover everything from national skills initiatives and competency frameworks, to soft skills, apprenticeships, and professional development. Crucially, we’ve also included deeply personal pieces that explore the realities of balancing impact assessment work with fertility treatment, parenting, and mental health.

This volume is a snapshot of a profession at a crossroads. As the environmental and planning landscape shifts rapidly around us, we must invest in people - not just for their technical expertise, but for the values, perspectives and human skills they bring to the table.
