Implementation

International law does not protect the right to pre-primary education and international documents generally omit references to education at this level. The Universal Declaration of Human Rights states that everyone has the right to education, hence the right applies to all individuals, although children are understood as the main beneficiaries.
The rights to education are separated into three levels:

• Primary (Elemental or Fundamental) Education. This shall be compulsory and free for any child regardless of their nationality, gender, place of birth, or any other discrimination. Upon ratifying the International Covenant on Economic, Social and Cultural Rights States must provide free primary education within two years.
• Secondary (or Elementary, Technical and Professional in the UDHR) Education must be generally available and accessible.
• Higher Education (at the University Level) should be provided according to capacity. That is, anyone who meets the necessary education standards should be able to go to university.

Both secondary and higher education shall be made accessible "by every appropriate means, and in particular by the progressive introduction of free education".

Compulsory education

The realisation of the right to education on a national level may be achieved through compulsory education, or more specifically free compulsory primary education, as stated in both the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights
