Abstract Background Eswatini continues to have the highest prevalence of HIV in the world, and one of the highest HIV incidences among adult populations (aged 15–49). This analysis reports on both key elements of study design/protocol and baseline results from an impact evaluation of an intervention incentivizing (i) initiation, enrolment, attendance or completion of some form of education, and (ii) lower risk sexual behaviour. Methods The impact evaluation employs a two by two factorial design in which participants are enrolled in either the incentive for education arm (‘education treatment arm’ providing a conditional cash incentive) or the control arm (‘education control arm’). In each of these arms, 50% of participants were randomized to also be eligible for selection – three times a year – to participate in a conditional raffle conditional on testing negative for curable STIs (syphilis and Trichomonas vaginalis). Results Baseline recruitment and screening occurred in 2016 when a total of 6055 individuals were screened of which 4863 participated in the baseline survey, and 4819 individuals were randomized into one of the study arms. The baseline prevalence of HIV, Trichomonas vaginalis, and syphilis among adolescent girls and young women 8.20% (397/4840), 3.31% (150/4533) and 0.17% (8/4830) respectively. Conclusions An educational cash incentive and raffle incentive impact evaluation that addresses adolescent girls and young women who are in-education and out-of-education has the potential to reduce HIV risk in adolescent girls and young women in Eswatini.
