In Mexico, telesecundaria students obtained lower scores in reading. This paper discusses the results of an investigation aimed at determining the effectiveness of a reading comprehension program implemented in secondary schools in a marginalized region. The design was to some extent experimental; with 16 groups of eighth grade experimental group and seven as control one. The results show that the control group had the same scores before and after the intervention, while the experimental group had an improvement in the second evaluation, therefore it is considered that the program was effective.
