Between 2000 and 2015, participation in the first year of preschool (Interactive II, age 4) increased dramatically from 7% to 63%, and that of the second year from 83% to 90%. The new curriculum gives special emphasis to early literacy skills which are critical both to success in learning and for developing a child's self-confidence and social interaction. Just 20% of 4-year-olds from the poorest households have access to preschool provision, compared to 80% of their wealthier peers.
