The formal delivery of education in the 21st century has been transformed radically from its 19th-century origins. The focus on the ways in which children learn is becoming critical to how education provision is structured in different educational contexts across the world. Exemplar 21st century schools are now tasked with an expanded range of roles in the postmillennium goal era. It is no longer enough to simply be able to record good enrolment rates at different educational stages. UNESCO and other international education bodies now require indicators of educational attainment through functional literacy indicators and test attainment results, including PISA and other international benchmarks.
