Each phase of the review process follows four steps:
1. Firstly the country under review, within six months from the beginning of its review, shall complete a self-assessment questionnaire on the implementation of the thematic cluster under review.
2. The responses to the self-assessment questionnaire will be reviewed by the reviewing States which will provide a written feedback to the State under review on the measures taken in the implementation of the Convention and relevant Protocols, as well as on the successes and challenges of such implementation. The written feedback shall be provided to the State under review within a timeframe not exceeding six months from the reception of the questionnaire. The feedback may also include request for further clarification or additional information.
3. At the final stage of the review process, each reviewing State, in close cooperation with the State under review and with assistance of the Secretariat, will prepare a list of observations indicating any gaps and challenges in the implementation of the provisions under review, best practices, suggestions and any technical assistance needs. The list will be based on the information provided by the State under review in the self-assessment questionnaire and the subsequent dialogue between the States. The lists of observations will be shared with the Working Groups of the Conference of the Parties (technical assistance, international cooperation, trafficking in persons, smuggling of migrants and firearms) based on their thematic relevance.
4. Finally, a short summary not exceeding 1,500 words of the list will be translated into all six official UN languages and made available for the Conference and its working groups.
