What key area does Wales have devolved powers over?

Wales has devolved powers over education and training, which means that the Welsh Parliament, also known as Senedd Cymru, has the authority to make decisions and enact laws relating to the education system in Wales. This includes the management of schools, higher education institutions, and vocational training. Devolution allows for localized governance that can address specific educational needs and priorities in Wales, distinguishing its approach from the rest of the UK.

The other areas mentioned, such as foreign affairs and national defense, remain reserved powers under the UK government, meaning that Wales does not possess devolved powers in these areas and cannot independently manage or legislate them. While health and social care are indeed devolved areas for Wales, the emphasis in the question focuses directly on the aspect of education and training, underscoring its significance in the context of devolved powers.
