Experimental Design
The program is being implemented in two waves. The first wave, carried out in the Spring se-mester of 2023, consists of two treatment arms and a pure control group (C). The two treatment arms involve an 8-week online tutoring program held during non-school hours, with sessions lasting 90 minutes and occurring twice per week. The difference between the two treatment arms is the number of students per tutor session, with one arm having two students (T1) and the other having three (T2). In the second wave, planned for the fall semester of 2023, an additional treatment arm (T3) has been added. In this additional arm, the 8-week program will have two students per tutor, but the tutors will receive additional training in socioemotional skills before the program begins.
