Lighting in classrooms refers to the entire set of devices that are installed to produce lighting effects. This aspect, although largely ignored, is of utmost importance in the development and learning of students within classrooms, laboratories and different educational sites. learning in schools. Their good or bad implementation has a great impact on teaching results, performance and fatigue for all those who use them. The objective of the research was to evaluate the lighting levels in the classrooms of a university in Mexico in accordance with the guidelines of NOM-025-STPS-2008. The lighting levels were evaluated in 16 classrooms distributed in two buildings. To determine the lighting of the classrooms, a Sper Scientific 840010 Pocket / Mini Light Meter was used. In the morning shift, only 51% of the total classrooms met the standard, during the afternoon shift, 88.88% of the classrooms on average met the standard. It is necessary to provide maintenance to the luminaires inside the classrooms so that they provide the amount of e lux indicated by the legislation. It is important to have good lighting inside the classrooms since it will allow greater comfort for the students and therefore better learning. Monitoring the lighting levels in the classrooms periodically will allow us to detect those where the lighting level does not comply with the provisions of NOM-025-STPS-2008.
