This guide draws on our practical experience and methodological expertise to offer clear, actionable advice for commissioners and researchers seeking to understand, design, transition to, or refine surveys that use more than one data collection mode. The guide will help you to:

• Think conceptually and clearly about mixed-mode surveys using the Total Survey Error framework
• Understand the pros and cons of mixing survey modes in relation to aspects such as cost-efficiency, response rates, mode-effects, accessibility, and timeliness
• Plan for development and continual improvement work including pilots, experimentation, and parallel runs of different methodologies
• Navigate a mode transition for an existing survey and consider the implications for data trends
• Future-proof your survey design and ensure that the voices of your stakeholders have been heard
• Relate your own research to our case studies which cover a range of audiences and mixed-mode designs
