As part of its new grant window on public expenditure tracking and absenteeism studies, TAP is producing a guide based on lessons learned, challenges faced, and strategies developed by former grantees. Following a six-step process from Developing a Topic to Undertaking Evidence-Based Advocacy, we will carefully outline the activities that PETS can involve and stories from practitioners who have been involved in "Learning by Doing" PETS exercises in the past. Expected Summer 2009.
