Evidence Applications


IWT Challenge Fund Evidence grants, ranging from £20,000 to £100,000, are intended for projects which gather evidence to design an intervention. Applications should describe how the improved evidence base will be used to design an intervention where there is a gap in approaches. Projects may include, for example, market research to design and baseline demand reduction interventions. Applicants are encouraged to develop evidence projects into full interventions as part of follow-on applications to the IWT Challenge Fund. Projects should last up to 2 years maximum.
