This chapter presents the simple patterns of a two-decade study into participation in education and attainment after the age of 16, in higher education, and throughout adult learners' lives. These findings are derived from the apparent differences in attainment by various social groups, girls and boys, types of schools, regions, and countries. The indicators covered in this chapter are the differences linked to family income, differences linked to special education needs (SEN), differences linked to precise age-in-year, differences linked to ethnicity, differences linked to first language, differences linked to recorded sex, participation in higher education, and finally, adult participation in education and training.
