HM Treasury is not making full use of the spending levers it has at its disposal to deliver a step change in the use of evaluation across government. We welcome the creation of the Evaluation Task Force and the increased emphasis on evaluation in the 2020 and 2021 Spending Reviews, whereby HM Treasury made greater use of its authority to set requirements for evaluation when it approved funding. However, we are disappointed that HM Treasury did not make use of these powers earlier, despite the NAO recommending this in 2013. HM Treasury’s final recourse is to withdraw funding or to reduce a department’s delegated authority limit if there is non-compliance with evaluation requirements. HM Treasury has not set up formal and standardised ways of tracking all spending review conditions across departments, including those related to evaluation. With few sanctions available to HM Treasury outside of the spending reviews, HM Treasury needs to make as much use of spending review conditions as it can. HM Treasury acknowledges that there is room for improvement in the quality and provision of evaluations across government despite its recent efforts. Recommendation: By November 2022, HM Treasury should set up a formal process for routinely tracking and following up on spending review settlement conditions relating to evaluation. HM Treasury should set out the range of interventions it will use if departments fail to meet the conditions.

No single body is responsible for upholding modelling and evaluation standards and monitoring their implementation. Within departments, ultimate responsibility for upholding standards and securing improvements lies with that department’s accounting officer. Supporting the accounting officer, the departmental directors of analysis own the application of the Analysis Functional Standard in their departments. Neither HM Treasury nor the Analysis Function 6 Use of evaluation and modelling in government currently monitor if accounting officers are discharging their responsibilities nor how well standards have been upheld. While HM Treasury is an important user of departments’ models, it does not comprehensively scrutinise and challenge a department’s quality assurance arrangements for the models it uses. To address this gap the Analysis Function intends to strengthen the governance framework for the Analysis Functional Standard, including introducing a self-assessment framework to assess performance against the standard. The Function told us it believes it does not currently have enough resources for this, but intends to request additional funding from HM Treasury. Recommendations: The Analysis Function, under the responsibility of the UK Statistics Authority, should: • put in place an appropriate assessment framework to monitor departments’ implementation of the Analysis Functional Standard; • act on areas for improvement identified through its assessment framework; and • agree with HM Treasury the funding it will provide for these roles. HM Treasury should set out how it plans to gain confidence that the outputs it uses from departments’ business critical models have been quality assured appropriately.

Good quality modelling and evaluation is hampered by challenges in sharing data and a lack of common data standards. Government does not always see data as a priority and data quality is often inadequate. We have drawn attention to poor data and a lack of joined up systems in numerous reports over the years, such as on supporting the vulnerable during lockdown, on tackling the tax gap, on effective regulation of gambling, on dealing with rough sleepers, and on identifying and tackling fraud and error. When producing and using models, poor data can lead to additional time and increased difficulty when quality assuring the model inputs. This difficulty is compounded by a lack of data standards across government which means there are inconsistent ways of recording the same information. When dealing with new situations, such as the rapidly changing pandemic, Government needs to be fast and agile at sharing data. Recommendation: The Cabinet Office should set out its progress in using its national data strategy to address the barriers to better sharing and use of data, including its development of cross-government standards for collecting, storing, recording and managing data.

Departments are not meeting government requirements on publishing evaluation plans and findings, and on transparency of models and their outputs. Transparency is critical for the public to understand the evidence behind decisions and how money is being spent. It also allows departments to learn lessons from past projects and from each other. However, ministers have the final say on whether evaluations should be published, and some parts of government are reluctant to Use of evaluation and modelling in government 7 publish their evaluations. It is only recently that HM Treasury has started to ask departments to explain why they do not plan to publish some evaluations. More than one-third of chief analysts say that only sometimes are they able to publish evaluation findings as required. Transparency of the models that departments use to make decisions is also poor: only 9 out of 17 departments have published their list of business-critical models since 2013, and only four have updated this since

Model producers and users do not adequately assess the range of plausible outcomes and are overly reliant on central estimates that do not reflect inherent uncertainty. All modelled information is uncertain, and decision-makers need information on the possible range of outcomes to plan well, manage risks and make better decisions. However, model producers do not routinely evaluate or communicate the uncertainty in their models. There is only limited evidence of departments using uncertainty analysis or developing contingency plans. Departments usually provide HM Treasury with a single central estimate and do not provide a range of uncertainty around it. HM Treasury does not check every model that departments develop. It does request further uncertainty analysis from departments on a case- by-case basis for those models it uses to make policy decisions or to agree additional spending. HM Treasury agrees that dealing with uncertainty properly is central to quality modelling and that it is important to improve standards in this area. Recommendations: As a key user of outputs from models, HM Treasury should routinely require departments to present the range of plausible outcomes. In its self-assessment tool, the Finance Function, under the responsibility of HM Treasury, should include consideration of how analysis and modelling are applied, including expectations on how accountants should analyse, manage and communicate uncertainty. 8 Use of evaluation and modelling in government 1 The centre of government’s role in improving evaluation and monitoring

Government’s view is that that transparency is critical for the public to understand the evidence behind decisions and how money is being spent, and that transparency should be the default position.44 The Analysis Function consider that transparency of evaluation findings allows departments to learn lessons from past projects and make them available for the future so the same mistakes might be avoided.45 However, the Finance Function explained that unlike the publication of statistics which is governed by regulation, the publication of evaluations depends on ministerial consent. Some parts of government are reluctant to publish their evaluations. For example, the Department for Work & Pensions was recently reluctant to publish insights from evaluations of the benefits system.46 Departments find it difficult to get approval from senior civil servants and the Cabinet Office to publish evaluation and protocols. More than one-third of chief analysts say that only sometimes are they able to publish evaluation findings as required.47

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
