Additional Trial Information
This research project analyses the Dual VET-Apprenticeship component of the Enhanced Skills for Sustainable and Rewarding Employment (ENSSURE) project (http://enssure.org.np/), financed by the Swiss Development Agency (SDC) and implemented jointly by the Council for Technical Education and Vocational Training (CTEVT) and HELVETAS Swiss Intercooperation Nepal (Helvetas).
The Dual VET-Apprenticeship program lasts two years. The first three months and the last month consist of classroom education. The months four to 23 combine two days of classroom education with three days of workplace training each week. Upon successful completion, graduates receive the formal Technical School Leaving Certificate (TSLC). To analyse the causal effect of the apprenticeship on the labor market situation, the research project randomizes applicants of the second cohort starting in November 2019. This cohort comprises training places for 960 apprentices.
The intervention consists of randomizing applicants for the limited places in the Dual VET-Apprenticeship.

Primary Outcomes (end points)
Primary Outcomes (explanation)
Secondary Outcomes (end points)
Socioeconomic status: We hypothesize that applicants with low socioeconomic status profit more from receiving access to training.
Male vs Female: We hypothesize that women profit more.
Schools: We hypothesize that the effect is higher for schools with better linkages to the employment sector.
Occupations: We hypothesize that the effect is higher for occupations with higher skill demands and higher labor market shortage.
Secondary Outcomes (explanation)
The randomization of applicants for the Dual VET-Apprenticeship is blocked by classes and gender. Classes are defined by school and occupation. In each block with sufficient over-subscription, 30% of applicants are in the control group and schools select apprentices from the remaining treatment group.
Experimental Design Details
The randomization will be conducted in the presence of ENSSURE using Excel. For transparency reasons, the randomization will be videotaped.
Randomization takes place on the student level, blocked by school, occupation and gender.
Was the treatment clustered?
Sample size: planned number of clusters
11 schools, 5 occupations, and gender yields 23 blocks since most schools offer one occupation with sufficient oversubscription and three school-occupations blocks have too few female applications.
Sample size: planned number of observations
The number of planned observations is 1412 applicants of which 446 become apprentices.
Sample size (or number of clusters) by treatment arms
1412 applicants in 23 blocks yields an average of 61 applicants per block.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Assuming power of 0.8 an effect size variability of 0.1, an R2 of 0.25, and a non-response rate of 25% yields a MDES of 0.25.
