Primary and Secondary

The NSW school system comprises a kindergarten to year 12 system with primary schooling up to year 6 and secondary schooling between years 7 and 12. Schooling is compulsory from before 6 years old until the age of 17 (unless Year 10 is completed earlier). Between 1943 and 2009, schooling was only compulsory in NSW until age 15.

Primary and secondary schools include government and non-government schools. Government schools are further classified as comprehensive and selective schools. Non-government schools include Catholic schools, other denominational schools, and non-denominational independent schools.

Typically, a primary school provides education from kindergarten level to year 6. A secondary school, usually called a "high school", provides education from years 7 to 12. Secondary colleges are secondary schools which only cater for years 11 and 12.

The NSW Education Standards Authority classifies the 13 years of primary and secondary schooling into six stages, beginning with Early Stage 1 (Kindergarten) and ending with Stage 6 (years 11 and 12).
