Abstract
This paper seeks to estimate the impact of increasing educational alternatives for low socioeconomic parents on school segregation, school choice and ultimately on educational outcomes. The wider range of educational alternatives is given by the Subvención Escolar Preferencial (SEP), a targeted voucher that allows low-income parents to attend private voucher schools with copayment for free. In order to estimate the impact of the SEP on school choice and educational outcomes we implement an encouragement design that randomly provides parents information on the SEP.

Intervention(s)
We implement an encouragement design in order to estimate the impact of the Subvencion Escolar Preferencial (SEP), a targeted voucher that allows low-income parents to attend private voucher schools with copayment for free. Therefore, we randomize two treatments that are meant to inform parents about the SEP and the wider range of educational options that they can access thanks to the program.

The first treatment is the provision of a report card designed for each preschool that includes information about the SEP and a list with all the secondary schools located in the same neighborhood, their addresses, telephone numbers and a map with their locations. In order to reinforce the idea that the SEP increases educational options for low socioeconomic parents, the schools' list is divided in three groups "schools that are free for anyone" , "schools that are free for SEP students" and "schools that charge fees" . The objective is to strengthen the idea that SEP students can now attend “schools that are free for SEP students” without paying.

The second treatment is the provision of the same report card, but it includes extra information on schools' characteristics: (i) test scores, (ii)a measure of the change in test scores between years, (iii) the official tuition cost for SEP and non SEP parents, (iv) the type of school (i.e. whether it is public or private) and (v) weather it has preschool and high school.

Parents in the control group are also given a report card that includes a flyer highlighting the importance of choosing the right school for their children and a list with all the secondary schools in their neighborhood, their addresses, telephone numbers and a map with their locations. The objective of this report card is to act as a placebo.

Experimental Design
Experimental Design
We implement an encouragement design in order to estimate the impact of the Subvencion Escolar Preferencial (SEP). Eligible preschools are randomly assigned to control group, treatment 1 and treatment 2. Randomization is done at the preschool level in order to avoid contamination among treated and control parents attending a same preschool. Randomizing at the preschool level also facilitates the implementation of the program, given that report cards are delivered through the preschools.
