Access to tertiary education among students enrolled in schools located in socioeconomically-disadvantaged areas is still limited. This fact tends to perpetuate inequalities. In this project, we study the impact of providing one-to-one mentoring sessions to students starting their last year of high school by randomly allocating a subset of students from over 50 schools in Catalonia to voluntary mentors who are college students or graduates. We focus on the effects of our intervention on the expectations of these students about the likelihood of attending university or vocational education and of direct entry into the labor force and about the pecuniary and non-pecuniary returns of these three options.

Primary Outcomes

Primary Outcomes (end points)
Expectations about the likelihood of attending tertiary education as well as about pecuniary and non-pecuniary benefits for different academic choices (attendance of university or vocational school and immediate entering in the labor force).
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Academic performance in the short run. We have also obtained legal and ethical consent to follow the students in the mid-term. Hence, budget permitting, we will also explore academic choices and performance during this longer time horizon.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We randomized 25% of the participating students in each school into treatment. Treated students are then assigned to a mentor within the pool of available ones using a matching algorithm that prioritises similarities between the mentor and the mentee.

Experiment Characteristics

Sample size: planned number of clusters
We randomize at the student level. We start with 809 students.
Sample size: planned number of observations
We expect to have 809 students.
Sample size (or number of clusters) by treatment arms
Treatment is randomized within schools. All 57 schools have treated and control students. We expect to have 201 treated students and 607 control students.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
