The BOBF indicator set includes over 100 indicators across 70 indicator areas, with one or more indicators per area. The indicators spanned the five BOBF “outcomes” and the 20 associated “aims” (four aims associated to each outcome), as well as different age groups between 0‑24 years. While interesting and useful to track progress for children and young people – which is indeed the main objective of the BOBF indicator set –, the economic cost of collating, analysing, and reporting data on more than 100 indicators is considerable and should be carefully considered when designing an M&E framework. Although there is not a specific or correct number of indicators for a results framework to be effective, the following questions are useful to ask when considering the addition of an indicator: i) is this indicator absolutely necessary to measure whether progress toward the desired goal is being achieved?; ii) will it create additional burdens in terms of data collection, analysis, and/or reporting?; and iii) how will this indicator help with the policy or programme M&E?.
BOBF’s indicators are almost exclusively outcomes focused. Additional indicators would thus have to be identified (and possibly developed) for the results chain of an M&E framework, which includes not only outcomes, but also inputs, activities, outputs, and assumptions. In line with its purpose which was to track how children were faring across the five national outcomes, relatively few of the BOBF indicator areas focused on the outputs that are generated by government action. 15 out of 70 indicator areas included indicators on access to, take‑up, or quality of services (OECD, 2024[4]). For example, out of the 16 indicator areas under Outcome 1 “Active and Healthy”, two covered output-level indicators: immunisation uptake (two indicators3) and access to mental health services (one indicator). The other 31 indicators were outcome level indicators. To properly monitor and evaluate whether government activities generate the desired results or outputs (i.e. parenting support, quality services, strengthened transitions, etc.), additional output-level indicators would need to be developed or articulated (and related data collected, if necessary).
Similarly, the indicator set does not define any indicators at the activity-level. Instead, the policy framework enumerated a list of considerably broad government commitments that were expected to trigger a change in the outcomes of interest. 69 commitments were attached to the framework’s “transformational goals”, and the other 89 referred to the five national “outcomes” in a direct manner. The framework also identified the government departments and/or agencies that were responsible for taking action with respect to such commitments. The set of 158 commitments had however a rather ambiguous nature, and no specific and verifiable indicators were created to enable the monitoring of these commitments. Instead, the annual report for the final year of implementation of BOBF shows that the monitoring of commitments was based on a self-evaluation undertaken by the government departments and agencies that were responsible for delivering on the commitments (DCEDIY, 2022[8]). For each of the commitments, those entities were asked to value their progress on a qualitative scale that goes from “done” to “ongoing”, “in progress”, and “not being progressed”. Ideally, this qualitative, self-reported system could be complemented with additional quantitative indicators that would contribute to the external verification of the delivery of governmental activities.
With respect to the more than 100 outcome‑level indicators, it is important to highlight that a very large number of BOBF’s indicator areas were based on self-reported personal experiences, behaviours, beliefs, and attainments (OECD, 2024[4]). The use of such proxy indicators are second-best solutions to fill data gaps and should only be used when no better data is available, pending the development of better data.
The BOBF’s indicator set report acknowledged the potential risks of self-reported indicators and included strategies to mitigate them. During the design of the indicator set, it was considered essential that the indicator areas prioritised by the Delphi process (see Section 3.1) would be retained in the final indicator set even if limited or no data were available for such area (DCEDIY, 2022[6]). For this purpose, where no appropriate data were identified for a particular indicator area, a range of markers known as “placeholders” were included in the indicator set. For instance, the indicator “number of children who receive direct support and/or accommodation from a domestic violence service each year” is a proxy for “number of households where domestic violence occurs”. Similarly, the indicator for “abuse” – total number of children at the end of the reporting period listed as “at ongoing risk of significant harm” on the Child Protection Notification System – is a proxy for the real extent of abuse. The inclusion of these placeholders ensured that areas that were identified as relevant by the Delphi process were not omitted from the set based uniquely on data availability reasons, and most importantly, it encouraged the future development of data on those topic areas considered essential.
Finally, and given the wide array of datasets used to construct the BOBF indicators set, the used indicators presented a high degree of variation in terms of their scope for disaggregation. Overall, the set of indicators does not have a consistent disaggregation in terms of key variables such as geographical location, age‑groupings, and vulnerability status of children and young people. The absence of certain disaggregation variables made it impossible to monitor outcome changes among particularly relevant sub-populations of children and young people. For example, age disaggregation would be of special relevance for poverty indicators, since no matter what statistical measure of poverty is adopted, adolescents aged 12 to 17 years old are much more frequently exposed to poverty than younger children (OECD, 2024[4]).
