Abstract
This project evaluates a novel sexual education intervention designed to reduce teenage pregnancy in rural communities in Peru. The novel intervention involves a mobile clinic staffed by a gynecologist and a psychologist who travel to public high schools to provide sexual health counseling over consecutive days per site. Alongside the mobile clinic intervention, we also evaluate the impact of a traditional teacher training program. The study is designed as a Randomized Controlled Trial (RCT). Schools are randomized into three groups: one received only the mobile clinic intervention, a second one received both the mobile clinic and teacher training, and a control group received no intervention. Outcomes of interest include changes in teenage pregnancy incidence, school performance and dropout rates, incidence of risky sexual activity, knowledge about contraceptive methods, and female aspirations.

2. School Dropout
3. Academic Performance
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
1. Self-Reported Incidence of Risky Sexual Activity
2. Female Aspirations
3. Knowledge about Contraception Methods
4. Mental Health
Secondary Outcomes (explanation)
1. An index of Self-Reported Incidence of Risky Sexual Activity will be constructed using the following variables from the endline survey:
- Respondent has engaged in unprotected sexual intercourse in the last 12 months [Q7.A.9]
- Respondent has never used a method to avoid pregnancy [Q8.A.1]
- In a hypothetical situation, respondent would not ask her partner to wear a condom during sex [Q9.A.2]
- In a hypothetical situation, respondent would not refuse to have sex with her partner if he did not want to wear a condom [Q9.A.3]

2. An index of Female Aspirations will be constructed using the following variables from the endline survey:
- Respondent thinks she will graduate from high school (if applicable) [Q1.3]
- Respondent thinks she will study at university (if applicable) [Q1.4]
- Respondent thinks she will graduate from college (if applicable) [Q1.8]
- Respondent wants to move to a bigger city or abroad [Q1.9]
- Respondent thinks she will not become pregnant before turning 20 years old [Q4.C.1]

3. One or more indeces related to Knowledge about Contraception Methods will be constructed using the following variables from the endline survey:
- Respondent knows to avoid reusing condoms [Q3.A.1]
- Respondent knows condoms have an expiration date [Q3.A.2]
- Respondent knows how to put on a condom [Q3.A.3]
- Respondent knows that condoms are an effective method of preventing pregnancy [Q3.C.1]
- Respondent knows that the withdrawal method is not as effective as using a condom to prevent pregnancy [Q3.C.2]
- Respondent is aware that using condoms consistently and right can prevent STIs [Q3.B.1]
- Respondent is aware that using pills consistently and right does not prevent STIs [Q3.B.2]

4. Mental Health will be measured using the GAD-7 Questionnaire included in the endline survey.

Experimental Design

Experimental Design
The study is designed as a Randomized Controlled Trial (RCT) with two treatment arms and a control group. We randomized 120 schools evenly across three groups. A third of schools were assigned to Treatment Arm 1 (T1), which consists of only the mobile clinic intervention; another 40 schools were assigned to Treatment Arm 2 (T2) including both the mobile clinic intervention and the teacher training course; and 40 schools serve as the control group (CG).
