Part of the INSPIRE project was to develop a checklist to assess and classify initiatives that foster responsible research practices. Following a Delphi method including two online surveys and a workshop, a checklist was drafted, piloted and revised until consensus among the INSPIRE team was achieved. The result is an extensive yet practical checklist that can be used by many stakeholders and for multiple purposes. It is used for the taxonomy of the spectrum of initiatives that soon will be made available at The Embassy of Good Science. The checklist can also be used by stakeholders to assess and improve their initiatives themselves, or by others who plan to implement an existing initiative, for example which they found in the spectrum on The Embassy!
