Evaluation and politics are related in a number of ways. While programme evaluators have traditionally tried to be neutral, objective and scientific in their assessment of programmes, the results of evaluation are inherently political -- and are used by politicians, programme administrators, special interest groups and other stakeholders for political purposes. The contributors argue that since evaluation cannot be divorced from its political context, the political dimension must be understood in order to conduct effective evaluations.
