The independent evaluation of the GLP NHPSP, mandated by the GLP NHPSP secretariat to the Swiss TPH, was conducted between December 2013 and March 2014. It covers programme achievements of the programme during the entire period of 2010 to 2013. The results-based assessment encompasses the categories relevance, effectiveness, efficiency, planning and implementation, impact and sustainability, and other considerations. The evaluation is based on a multitude of data sources including an online survey and extended personal interviews of stakeholders of all levels and layers within in the organisation. The analyses of the entire evaluation resulted in a set of recommendations for the way forward of the GLP NHPSP.
