Additional Trial Information
This project evaluates the impact of schools administered by Bridge International Academies in Kenya on a variety of student outcomes using a large-scale randomized scholarship experiment. The evaluation is centered on a scholarship program that selected 10,000 students chosen by a lottery from among about 25,000 applicants from pre-K to grade 7 to attend any of the 405 Bridge schools in Kenya starting in January 2016. The scholarship provided tuition for students to attend Bridge schools for two years.

Primary Outcomes (end points)
The project will examine the effect of Bridge on test scores in core primary schools subjects in the Kenyan educational system: Mathematics, English, Kiswahili, Science, and Social Studies. Other outcomes of interest are described in the plan for subsequent analysis.
Primary Outcomes (explanation)
Secondary Outcomes (end points)
Secondary Outcomes (explanation)
26,224 scholarship applications were received. Scholarships were randomly assigned at the individual level. The probability of being assigned a scholarship depended on the specific Bridge location to which a student applied. This location specific probability was determined by requirements set by the donor agency and Bridge regarding the share of students attending on scholarship and the share of scholarships awarded to current Bridge students. 14,112 were followed at endline.
Experimental Design Details
Randomization was carried out by random numbers generated in Stata.
