The contemporary construct about “quality of life” involves the analysis of material resources and subjective well being, the assessing the welfare or satisfaction of citizens is a national and international priority, mainly is important on populations with important functions in society. In this study, quality of life was assessed in a population of 473 students that were being training to teach in metropolitan area of Monterrey. A tests with four scales that integrates objective and subjective components of quality of life was used, and this test was adjusted by Arita (2005, 2006) and Tánori (2011). This population is very important because historically have had a job stability with support of union membership. We found that there are differences as to whether student teachers have a family that exercises the profession of teaching; other relevant variables were the number of family members and the amount of household goods. Particularly the subjective component is the best to explain the quality of life of teachers. We concluded that reformist policies on education may change teachers’ perception before and after the reform. Keywords: quality of life, labor union, teachers, reform, basic education.
