The UK has devolved education systems and there are significant curriculum variations between Wales, England, Scotland and the six counties of Northern Ireland. England was first to introduce a new ‘Computing’ curriculum in September 2014, which made coding and programming compulsory for all ages from 5 through to 16. Wales introduced the Digital Competence Framework in September 2016, to be fully operational by 2018.
