This paper examines whether the practice of transcendental meditation influences different educational outcomes in a school located in the department of Antioquia, Colombia. For this purpose, a meditation project implemented during three years in secondary students is considered as a case of study. The results suggest that for this particular school the different educational outcomes are not strongly positively influenced by the meditation technique, and there is even a negative impact on the philosophy scores and the various school rates. Potential explanations for the observed outcomes are provided.
