Mexico is one of the world’s most populous countries and is known for its vibrant and diverse culture. Spanish is the dominant language in Mexico; according to 2020 estimates, 93.8% of the population speaks only Spanish, while 5.4% speaks both Spanish and an Indigenous language. English is also used in some academic, business, border, and tourism contexts, but Spanish remains the main language of daily life and university instruction.
While the language of instruction for most Mexican universities is Spanish, some universities offer courses or programs in English, especially through international, exchange, or selected degree options. English-taught availability varies by institution, campus, and semester, so students should always confirm the language of instruction for their chosen program.
If you are an international student planning to study in Mexico, you may need to provide proof of proficiency in Spanish or English, depending on the language of instruction and the requirements of your chosen university or program. Many universities state their requirements as a CEFR level, such as B1 or B2, and may accept different certificates or internal placement tests.
Read on to find out some of the common language tests needed in Mexico for international students.
Language Proficiency Tests Needed in Mexico
Spanish Language Tests for International Students
Here are some of the common Spanish language proficiency tests accepted by Mexican universities and exchange programs. Accepted tests and score levels vary, so always check the official admissions or international office page for your specific university.
1. DELE – Diploma de Español como Lengua Extranjera
The DELE is a widely recognized Spanish proficiency exam issued by the Instituto Cervantes on behalf of Spain’s Ministry of Education, Vocational Training, and Sports. Some Mexican universities and exchange programs accept DELE certificates as proof of Spanish language proficiency.
DELE is divided into six CEFR levels, ranging from A1 to C2. The exams assess overall communicative competence in Spanish, including reading, listening comprehension, writing, and speaking.
Each DELE exam follows the Common European Framework of Reference for Languages (CEFR). Unlike many language proficiency tests, DELE diplomas do not expire.
DELE results are reported as pass or fail for the level the candidate takes. The exams are generally scored out of 100 points, but candidates must also meet the minimum score required in each exam group, so students should check the scoring rules for their chosen DELE level.
Examples of Mexican universities that mention Spanish B2 requirements include Universidad La Salle, which lists a DELE B2 certificate for international students, and Universidad Anáhuac México, which requires a Spanish B2 certificate for non-Spanish-speaking exchange students.
2. SIELE – Servicio Internacional de Evaluación de la Lengua Española
The SIELE (Servicio Internacional de Evaluación de la Lengua Española) is a Spanish proficiency test designed to assess and certify the Spanish language skills of non-native and native speakers. SIELE is promoted by the Instituto Cervantes, the National Autonomous University of Mexico, the University of Salamanca, and the University of Buenos Aires.
It is recognized internationally and can be used for academic, professional, or personal purposes. The SIELE Global exam consists of four sections: Reading Comprehension, Listening Comprehension, Written Expression and Interaction, and Spoken Expression and Interaction.
SIELE scores are mapped to the Common European Framework of Reference for Languages (CEFR). The SIELE Global exam has a maximum score of 1000 points, with up to 250 points for each section, and the certificate is valid for five years. Universities usually set their own required CEFR level or score, rather than using one universal minimum score.
Examples include the Instituto Politécnico Nacional, which states that all IPN courses are taught in Spanish and that non-native Spanish speakers must take the SIELE test, and Instituto Tecnológico Autónomo de México, which recommends at least B2-level Spanish or one year of university-level Spanish for students taking most undergraduate and engineering courses in Spanish.
English Language Tests for International Students
Some universities in Mexico offer courses or programs in English, so demonstrating English proficiency may be necessary for those options. Here are some of the most common English language tests accepted by universities and programs.
1. IELTS – International English Language Testing System
The International English Language Testing System (IELTS) is one of the most widely recognized English language proficiency tests in the world. It assesses the English language skills of people who wish to study, work, or live in an English-speaking environment.
The IELTS Academic version is typically used by individuals who want to study at undergraduate or postgraduate levels or need English proof for professional registration.
The IELTS Academic test consists of four sections: Listening, Reading, Writing, and Speaking. IELTS scores are reported on a nine-band scale, with Band 1 representing a non-user and Band 9 indicating an expert user.
For English-taught courses in Mexico, IELTS requirements vary by university and program. Some institutions state the requirement as a CEFR level, such as B2, instead of a fixed IELTS score. For example, Tecnológico de Monterrey offers IELTS Academic certification at its Monterrey campus, but students should check their specific program page to confirm whether IELTS is accepted and what score is required.
2. TOEFL – Test of English as a Foreign Language
If your program is taught in English or requires English proficiency, you may need to take a TOEFL test. Mexican universities and language centers may refer to TOEFL iBT or TOEFL ITP, so it is important to confirm which version your program accepts.
The Test of English as a Foreign Language, commonly known as TOEFL, is an internationally recognized English language proficiency test. The main TOEFL version used for university admissions is TOEFL iBT.
- TOEFL iBT is taken at an authorized test center or at home through the TOEFL iBT Home Edition. It assesses Reading, Listening, Speaking, and Writing. Since January 21, 2026, TOEFL iBT reports scores on a 1 to 6 scale, with a comparable 0 to 120 score included during a two-year transition period.
- TOEFL ITP is an institutional test used by some universities and language centers. It usually assesses Listening Comprehension, Structure and Written Expression, and Reading Comprehension. It should only be used for admission or enrollment when the specific university or program says it accepts TOEFL ITP.
Examples of Mexican institutions that administer TOEFL ITP include the Universidad Autónoma de Nuevo León and Tecnológico de Monterrey. Because TOEFL requirements vary and many institutions are still updating their score requirements after the 2026 TOEFL iBT scoring change, always confirm the accepted TOEFL version and minimum score with the admissions office or program coordinator.
If you are planning to attend university in Mexico, the above Spanish and English language proficiency tests are among the most commonly used. It is crucial to contact the admissions office or international office of the university you plan to attend to confirm its specific language proficiency requirements and which tests it accepts. Additionally, be mindful of application deadlines for language proficiency exams, as they can vary.
