The Project / Evaluation

Menttores follows an experimental research strategy (RCT) to measure the impact on results in a rigorous way.

Participating students were selected through a lottery from the pool of all applicants to the program.

Students who were not selected for participation constituted the control group. Outcomes were measued before and after the program both for participants and non-participants.

We compared results of students and families of the intervention and control group.

What participants say about Menttores

It was very useful for pupils to get personalised attention and help with their schoolwork. Sometimes pupils couldn´t cope with math by themselves. The help from the mentors made a huge difference

Math teacher at the school

She didn’t “just” make my daughter like maths. Now she wants to do her homework. She wants to study. She gets up at 5am to revise for exams. She’s more confident and has a better attitude. She is self-confident
