The Africa Gender Innovation Lab (GIL) is partnering with Pro-International Health (PHI) to evaluate a vocational training program. This program is part of an overarching strategy implemented by Pro-Health International (PHI)— Integrated Child Health and Social Services Award (ICHSSA)— to mitigate the impact of HIV/AIDS. The targeted beneficiaries of the vocational training program are rural women residing in the states of Bauchi and Adamawa in Nigeria who are caregivers of children living with HIV (CLHIV), women with children and living with HIV (PLHIV), and caregivers of children that have been exposed to sexual violence and other abuse, as well as caregivers of HIV exposed infants. The vocational training program seeks to impart technical skills in non-farm trades, such as tailoring, and dry and wet grinding as well as life skills such as problem-solving, collaboration and negotiation. The program also includes the provision of an asset transfer to women who complete at least 70% of the training. Alongside, PHI will also implement a buddy program - where trainees are paired together at the beginning of the program - which is designed to address women’s social network constraints. Two versions of the buddy program will be tested: self-selection of peers and a random matching process.
Using a randomized control trial design, the study will evaluate the impact of the vocational training program on women’s labor market outcomes such as employment and earnings; intra-household decision-making and agency; psychological wellbeing; and adherence to HIV-treatment. The findings of this study will also shed light on the effects of an innovative social network intervention and the optimal delivery mechanism for such an intervention.

Experimental Details


The interventions include vocational training program, life skills curriculum training, asset transfer and buddy program.

The vocational training program includes three key components. The first component offers technical skills in three economic trades of tailoring, wet grinding and dry grinding. In the second component, the program offers training in life (non-cognitive) skills such as negotiation, collaboration, and problem solving and decision-making. The third component of the vocational training program includes an asset transfer which has been embedded to incentivize trainees to complete the training.

The buddy program is an add-on intervention that seeks to address constraints relating to women’s social networks. Under this program, each trainee will be paired with a co-trainee, i.e., a buddy, from her training group. This pairing will be carried out in two ways: (1) randomly matching a trainee with another co-trainee in the training group, (2) allowing the trainee to select her peer among trainees in her group.

Experimental Design

Experimental Design
To estimate the causal impact of the program, Randomized Control Trial (RCT) will be used. The 2,887 eligible beneficiaries will be individually randomized into three treatment arms and a control group after stratification based on LGAs. The three experimental groups include:
(i) vocational training + life skills training curriculum + asset transfer (defined as “core” program);
(ii) “core” program + buddy program with assortative marching;
(iii) “core” program + buddy program with random matching;
(iv) control group (which will not receive any intervention).
Training groups of approximately size 10 to 15 for each economic trade area will be formed within each treatment group. The vocational training program and add-on interventions will be delivered at the training group level.
