This study will identify the impact of information on students' decision making and demand for education. We will provide students in 600 randomly selected Ghanaian junior high schools with information about senior high school application strategies, selectivity, and exit exam performance. We will then examine changes in their beliefs, subsequent senior high school application and enrollment decisions, and educational attainment, identifying how access to information impacts student welfare. We will also evaluate the cost-effectiveness of providing information directly to parents relative to targeting only students and teachers.

Experimental Details


The GUIIDE intervention randomly selected 600 junior high schools to receive:
1) Booklets containing information on senior high school application strategies and the selectivity and exam performance of local options
2) A video-screening and question and answer session with additional guidance and information.

Primary Outcomes

Primary Outcomes (end points)
Beliefs, application behavior, admission outcomes, educational attainment, student welfare.
Primary Outcomes (explanation)
Primary Outcomes: Short-term
- Improved accuracy of beliefs about senior high school (SHS) quality (performance on the secondary school certification exam, SSCE)
- Improved accuracy of beliefs about SHS admission standards
- Increased use of admissions criteria in choosing SHS application set
- Increased quality of the SHSs to which students apply, conditional on admissions standards
- Increased likelihood that students revise their SHS application set between baseline and midline
- Decreased likelihood of application errors (e.g., ranking less-selective SHS higher than more selective SHS)
- Improved SSCE performance of assigned school

Primary Outcomes: Long-term
- Increased likelihood of attending SHS
- Decreased likelihood of attending an SHS other than the one assigned through the computerized school selection and placement system (CSSPS)
- Increased likelihood of completing SHS
- Increased likelihood of completing SHS on time
- Improved SSCE performance and cognitive skills

Secondary Outcomes: Short-term
- Increased likelihood that students have seen information booklet or video
- Increased parental information about SHS and application process
- Improved scores on the junior high school exit exam (Basic Education Certification Exam, BECE)

Secondary Outcomes: Long-term
- Improved educational and career aspirations
- Delayed age at first sex, childbearing, and marriage
- Improved mental health and socio-emotional skills
- Decreased drug abuse and delinquency

Experimental Design

Experimental Design
We randomly assigned 900 junior high schools in the Ashanti Region of Ghana into one of three groups: T1) control, T2) information to students and teachers, T3) information to students, teachers, and parents. Students in T1 schools received no information. We provided students and teachers in T2 and T3 schools with information booklets and conducted a workshop during school hours. In addition, in T3 we conducted parent workshops, providing information directly to parents.

We overlay this randomization with a secondary experiment in which half of each group participated in a baseline survey and half did not. This baseline survey may have prompted students to think more about the application process and encouraged them to seek out more information. By administering this survey in a random subset of schools (T1a, T2a, and T3a), we can measure how this increase in the salience of the applications, independent of the provision of additional information, changes students' knowledge and subsequent decisions.
