Into the 1965 icerd, the two international covenants of 1966, and every other core international human rights convention since.
In order to meet its reporting obligation, each state part must submit a comprehensive initial report usually within one year of the treaty entering into force for that state(two years in the case of ICESCR and CRC). It must then continue to report periodically in accordance with the provisions of the treaty (usually every four or five year) on further measures taken to implement the treaties. The report must set out the legal, administrative and judicial measures taken by the state to give effect to the treaty provisions, and should also mention any factors or difficulties that have been encountered in implementing the rights. In order to ensure that reports contain adequate information to allow the committees to their work, each treaty body issues guidelines on the from and content of state report. These guidelines are issued in a compilation document(HRI/GEN/3) which is updated regularly. The treaty bodies are in the process of considering draft harmonized guidelines on reporting under the international human rights treaties
