This study aims to evaluate a new methodology of focalization of training as well as to analyze peer effects among low-income women in Chile. The main objective is to increase female participation in the Chilean labour market, reducing the existent gender gap. Results suggest benefits at an individual level, rather than effects for the labour market as a whole. In general, tracking groups ("high" and "low" groups) have a better performance than the non-tracking group, particularly for participants that belong to the "low" group. Also, it seems as though belonging to the "high" group has no effects on the satisfaction level of participants. No impact is identified on wages or family income; hours, days or Sundays worked; number of jobs; nor improvements in the labour market. There are no indicators related to employability, job quality or job formality.

Primary Outcomes
Primary Outcomes (end points)
Personal & family benefits, likelihood work with peers, situation a year or 2 ago; working conditions, family income, chance of finding employment, perception of participants.
Primary Outcomes (explanation)
Scores related to personal benefits, family benefits, likelihood to work with peers, effect on happiness, comparison to the personal and work situation a year or two ago; number of hours, days or Sundays worked; monthly wage and family income; type of job contract; chance of finding employment, all of such according to the different types and levels of participants. Also, some of the results relate to the perception of participants, about the courses undertaken and about their colleagues participating in such courses.

Experimental Design
Experimental Design
Firstly, participants were selected randomly for the treatment and control group. The treatment participants were then assigned randomly in a "mixed"/"heterogeneous" class and in a "selection"/"homogeneous" class. From the latter class, some were allocated in a "high" group and others in a "low" group, according to the propensity to work index (obtained from the CASEN survey). If participants had a propensity to work index above its median, they were allocated in the "high" group and if it were below, they belonged to the "low" group.
