Prepa Tec Valle Alto is the newest and smallest of the five Prepa Tec high schools. It was inaugurated in August 2005 with a class of less than 100 students. The school is located in the southern part of Monterrey, in the fast developing Valle Alto region of Mexico. It is situated next to the National Highway on top of a hill.
Prepa Tec Valle Alto is the smallest school by size and by student count in the Prepa Tec High School system; it has fewer than 350 students and 13 classrooms. The school offers the standard Bilingual, Bicultural or International Baccalaureates.
With Prepa Tec getting ready for the fifth generation of students, an expansion is under way; it is next to Aulas II, in which they will expand the gymnasium and make at least eight more classrooms. Work on the expansion started in mid-January 2009.
Prepa Tec Valle Alto is noted for its calm environment, for its cooler weather (due to it being situated on a hill) and for its small class sizes.
