Promoting Language Policy seeks to provide robust evidence for the value of languages to key issues of UK public policy and to facilitate contact between policymakers and academics. To date the project has had two major outputs. In collaboration with RAND Europe, it produced more rigorous evidence for the economic impact of the lack of language skills in the UK (The economic value to the UK of speaking other languages 2022). The study found that languages play a significant role in international trade and that not sharing a common language acts as a non-tariff trade barrier. A key finding is that investing in languages education in the UK will most likely return more than the investment cost. The benefit-to-cost ratios are estimated to be at least 2:1 for promoting Arabic, French, Mandarin or Spanish education, meaning that spending £1 could return approximately £2. The project has also created an online repository of UK language policy documents for policymakers, stakeholders and researchers (https://www.promotinglanguagepolicy.org/languagepolicydocuments). The repository’s emphasis is primarily on legislation – it holds just over 1,500 pieces of primary and secondary legislation – but it also features a range of documents which make policy recommendations (e.g. by the British Academy and British Council).
