What Is High School Called in Mexico: Preparatoria

High school in Mexico is most commonly called “preparatoria” (often shortened to “prepa”) or “bachillerato.” Both terms refer to the upper secondary level of education, covering grades 10 through 12 and typically lasting three years. While the two words are often used interchangeably in everyday conversation, they can carry slightly different connotations depending on the type of school and the academic track a student follows.

How Preparatoria and Bachillerato Relate

“Bachillerato” is the broader, more formal term for the entire upper secondary stage of education in Mexico. Think of it as the official label for the level itself, similar to how “secondary education” is used in English. “Preparatoria,” on the other hand, literally means “preparatory school” and is the name most Mexicans use in daily life when talking about their high school. Some schools use “preparatoria” right in their name, while others go by “bachillerato” or a variation like “bachillerato general.” In practice, a student saying “estoy en la prepa” is the equivalent of an American teenager saying “I’m in high school.”

Grade Levels and Semesters

Mexico’s preparatoria runs on a semester system rather than the year-long grade levels common in the United States. The three years break down into six semesters:

  • 10th grade equivalent: First and second semesters (primer y segundo semestres)
  • 11th grade equivalent: Third and fourth semesters (tercer y cuarto semestres)
  • 12th grade equivalent: Fifth and sixth semesters (quinto y sexto semestres)

Students typically enter the preparatoria around age 15, after completing “secundaria” (middle school, grades 7 through 9), and finish around age 18.

The Two Main Academic Tracks

When Mexican students enter upper secondary education, they choose between two primary streams. The track they pick shapes their coursework and, to some extent, their options after graduation.

Bachillerato General

This is the academic track designed to prepare students for university. Schools offering this stream sometimes call themselves “preparatoria” or use the term “propedéutica,” meaning it serves as a foundation for further study. The curriculum focuses on general education subjects: math, science, literature, history, and languages. Students who plan to pursue a bachelor’s degree at a university typically follow this path.

Bachillerato Tecnológico

The technological track combines general education with vocational training. It also lasts three years and covers many of the same core academic subjects as the bachillerato general, but students additionally choose a specialization, known as a “carrera.” Specializations include fields like human resource management, business administration, and information technology. Graduates of this track can enter the workforce with practical skills or continue to higher education, making it a flexible option. You may also hear this stream called “bachillerato bivalente” or “bachillerato técnico,” reflecting its dual purpose.

Educación Profesional Técnica

A third, less common path is the professional technical track. This is a four-year vocational program focused entirely on career preparation. Unlike the other two streams, students who complete this track are generally trained to enter the workforce directly rather than continue to a university.

How Students Get Placed

In Mexico City and its surrounding metropolitan area, students transitioning from secundaria to preparatoria take a standardized entrance exam administered by an organization called COMIPEMS (the Metropolitan Commission of Public Institutions of Higher Secondary Education). The exam helps determine which type of upper secondary school a student will attend and at which specific institution they will be placed. Outside of Mexico City, the admissions process varies, but most public preparatorias use some form of entrance evaluation to assign students.

Why the Terminology Matters

If you are evaluating a Mexican student’s academic credentials, translating school records, or simply trying to understand someone’s educational background, knowing these terms helps you place them correctly. A “certificado de bachillerato” is the diploma issued upon completing upper secondary education and is the standard requirement for admission to Mexican universities. It is the direct equivalent of a U.S. high school diploma. Whether the document says “preparatoria,” “bachillerato general,” or “bachillerato tecnológico,” it represents the same educational level: grades 10 through 12, completed over three years (or four in the case of the technical vocational track).
