HMT told us it is only recently that it has started to ask departments to explain why they do not plan to publish some evaluations.48 The Evaluation Task Force raised the issue that there were evaluations that the centre of government did not know about because they had never been published.49This Committee has regularly highlighted departments’ poor timeliness in publishing evaluation findings. The Evaluation Task Force has a core responsibility to maintain a public register of evaluation plan summaries and trial protocols and to encourage departments on the timely publication of evaluation results on GOV.UK. This is to manage ‘publication bias’, the risk that evaluations which have negative findings may not get published,50 to support action on evaluation results and to improve accessibility for decision-makers. To meet its core responsibilities, the Evaluation Task Force explained that it is creating a website which sets out what evaluations departments intend to publish when, and whether this has happened.51 It hopes that this will allow the public to easily see whether departments are complying with requirements and allow the Evaluation Task Force to hold departments to publishing what they have promised.52 HM Treasury told us it has recently started to require that departments publish an evaluation strategy and, given that communication is a central part of evaluation, HM Treasury expects the evaluation strategy will include a communication strategy.53
