Devolution is the statutory granting of powers from the central government of a sovereign state to govern at a subnational level, such as a regional, local, or state level. It is a form of decentralization. Devolved territories have the power to make legislation relevant to the area. Devolution differs from federalism in that the devolved powers of the subnational authority may be temporary and ultimately reside in central government, thus the state remains, de jure unitary.
Since devolution, education policy in the four constituent countries of the UK has diverged: for example, England has pursued reforms based on diversity of school types and parental choice; Wales (and Scotland) remain more committed to the concept of the community-based comprehensive school.n 2008 a unique new curriculum-the Foundation phase-was rolled out to all schools in Wales. It began for 3- to 4-year-olds and by 2011 is in place for 3- to 7-year-olds. It is based on experiential learning, in small groups, with a teacher ratio of 1:8 for the youngest ages.
