Though increasing attention has been paid to the subject in recent years, methods to ensure evidence‑based decision making on integration remain underused. Almost all OECD and EU countries have a strategic framework that addresses integration of at least some key categories of migrants such as beneficiaries of international protection, but few perform systematic evaluation of their integration measures. The lack of evaluation of integration policies and strategies makes it difficult to assess whether new policies achieve their intended goals or merely sound good in theory.
Integration is often a major expenditure for host-countries, and in light of that expenditure, countries should have a vital interest to ensure that their methods, training, and assessment services are relevant and effective in delivering the intended outcomes and that they are continuously updated and improved. This is especially important where participation is obligatory, or where countries have decided to impose penalties for failure to reach a certain language threshold. If migrants are to spend this time away from the labour market, they should do so in a way that will be most beneficial to them in the long run. Evaluation enables countries to understand whether migrants are accessing the right integration measures for their needs, if they are in fact learning the host-country language, and whether the skills and knowledge gained are actually facilitating access to the labour market and helping them meet other integration goals. In the wider sense, systematic evaluations of integration measures can also be understood to constitute a duty towards taxpayers, wherever schemes are financed from the public purse. Evaluation is a necessary condition for effective results-based management and can help authorities avoid overlap and waste.
As integration is a process that occurs over time, improvements in outcomes may not necessarily be tied to policies. Changes will occur even in the absence of any policy. Participation in a programme designed to find jobs for unemployed immigrants may not, for example, but the sole reason that a migrant becomes employed. EU-wide, more than 1 in 3 of the low-educated non-EU migrants who were unemployed in 2018 had found a job one year later, whether or not they participated in an integration programme. For established programmes, where outcomes do fall short of objectives, an evaluation can also help policy makers understand why that is the case. If migrants are not completing the programmes as designed, it may be that the programme is not meeting migrants’ needs. On the contrary, it could be that their needs would be met with fewer services. It could also be that communication about the benefits of the programme is falling short, or that targets are set to unreasonable levels during the amount of time allocated. Without data, it is also difficult to argue for changes, especially as each change comes with an investment of both time and money.
The understanding of not only outcomes, but also of the “why” and “how” programmes are most effective, enables authorities to make tailored improvements that could deliver significant return on investment as the economic contributions of impacted migrants increases. A study of the decision to develop individual integration plans in Finland found that migrants were subsequently offered more language hours and obtained significant improvement in employment outcomes (Sarvimäki and Hämäläinen, 2016[64]). Evaluation can provide valuable lessons regarding what measures could increase attendance by certain hard-to-reach groups, such as women and the elderly, as well as how to decrease drop-outs. An additional benefit of evaluation is knowing which programmes do not work before significant further investment is made. In some cases, insights gained through evaluation have led to programming being discontinued. For example, in Denmark, a decision to reduce welfare benefits in tandem with offering expanded and improved early language classes to refugees was discarded when it showed the reduction in benefits had no positive labour market effects.
