Article 35 of the UN Convention on the Rights of Persons with Disabilities requires that all signatory states submit reports (state party reports) on CRPD implementation in their country. Along with other information, these reports must include a description of measures the States parties have taken to implement the Convention. All United Nations human rights conventions provide for this medium of the State party reports, and for review of these reports by the relevant UN human rights treaty body.
There are four steps to the report & review procedure:
Article 35 para. 1 of the UN CRPD requires every signatory state to submit an initial report within two years after the Convention enters into force in that state. After the initial State party report is submitted, additional reports (Periodic Reports) fall due every four years (Article 35 para. 2 of the UN CRPD). However, the Committee on the Rights of Persons with Disabilities (the treaty body for the UN CRPD) is entitled to request another report at any time, independently of the periodic reporting cycle (also Article 35 para. 2 of the UN CRPD). The Committee has issued reporting guidelines advising states on the form and content of their reports:
