While the report of the States party concerned will form the main basis of the review, there are other sources of information available to the CEDAW Committee to assist it in its review.
These include country-specific reports submitted by specialised UN agencies such as WHO, ILO, UNESCO, UNICEF etc., reports of UN Special Rapporteurs such as the Special Rapporteur on Violence Against Women, shadow reports of NGOs - national and international, reports submitted by the States party concerned to other treaty bodies, the Concluding Observations of other treaty bodies and the results of research conducted independently by individual members of the CEDAW Committee.
How the report of the States party compares in relation to this body of information is an issue to consider.
