comprehensive sexuality education in schools; c. Concrete results in terms of women’s sexual and reproductive health. This includes assessing the impact of sexual and reproductive health policies in reducing fertility rates, adolescent birth rates, maternal mortality ratios and the prevalence of sexually transmitted infections. When dealing with quantitative factors, NHRIs need to assemble disaggregated data on sex, age, urban/rural residence, and ethnicity, level of education, wealth, disability and geographical location (if possible). Additionally, these indicators should be: a. Continuously or frequently measurable; b. Objective so as to permit comparison across time, countries and/or sub-regions; c. Programmatically relevant to enable priory setting and identification of accountability gaps; and d. Where possible subject to local audit to promote accountability to the populations served.15 One distinct feature of HRBA to monitoring and evaluation is the principle of accountability, ensuring independent review of governmental policy and budgetary efforts. NHRIs in compliance with the Paris Principles are in a privileged position to participate in government-led monitoring and 15 OHCHR A/HRC/21/22, para. 63. 88 evaluation systems and to provide shadow reports, whenever necessary. NHRIs should bear in mind that the ultimate aim of monitoring and evaluation is to identify policy and systemic failures in order to recommend corrective actions and influence the formulation of the next policy cycle from a human rights perspective.
