Uzbekistan has a high literacy rate, with 99.9% of adults above the age of 15 being able to read and write. However, with only 76% of the under-15 population currently enrolled in education (and only 20% of the 3–6 year olds attending pre-school), this figure may drop in the future. Students attend school Monday through Saturday during the school year, and education officially concludes at the end of the 12th grade.
