About this Exam

The PAU (Prueba de Acceso a la Universidad), often referred to as Selectividad, is the critical entrance examination for students in La Rioja, Spain, wishing to pursue undergraduate studies at Spanish universities.

This comprehensive assessment evaluates the knowledge and skills acquired during high school (Bachillerato) and determines eligibility for university admission, as well as the specific degree programs students can enroll in based on their final scores.

What the Course Entails and Exam Details

The PAU exam in La Rioja evaluates a broad range of subjects.

The exam is structured into two main parts:

  • General Phase (Obligatory): This section assesses fundamental knowledge and includes exams on Spanish Language and Literature, History of Spain, and a Foreign Language (usually English, French, etc.). In La Rioja, students also typically examine in the co-official language if applicable, though primarily Spanish is used.

  • Specific Phase (Voluntary): This phase allows students to improve their admission score by taking exams in subjects related to their intended university degree (e.g., Mathematics, Biology, Chemistry, Physics, Art History, Economics). These subjects are weighted more heavily depending on the relevance to the chosen field of study.


What to Expect in the Final Exam

The PAU exams are rigorous written assessments conducted over several days.

  • Format: Each subject exam typically lasts 90 minutes. The format varies by subject but generally includes essay questions, analysis of texts or historical documents, problem-solving (in sciences and math), and practical exercises.

  • Scoring: The final score is a combination of the student's average grade from Bachillerato (60%) and the PAU General Phase score (40%). The Specific Phase can add up to 4 additional points to the total score, making the maximum possible score 14.

  • Rules: Strict academic integrity rules are enforced. Students must bring valid identification and are not permitted to use unauthorized materials or electronic devices during the exams.


How to Study and Exam Centers

Effective preparation is key to succeeding in the PAU.

  • Study Strategies: Students should create a structured study plan early on, focusing heavily on reviewing past exam papers (exámenes de años anteriores) provided by the University of La Rioja (UR). Understanding the criteria used for grading (criterios de corrección) is crucial. Active learning techniques, summary notes, and study groups can also be highly beneficial.

  • Exam Centers: In La Rioja, the PAU is organized and administered by the Universidad de La Rioja (UR). The exams are typically held at the university campus in Logroño, and sometimes at designated high schools (institutos) throughout the region, depending on the number of registered students. Students will receive specific information regarding their assigned exam center well in advance of the test dates.


Job Opportunities from the Course

Passing the PAU and achieving a competitive score does not directly lead to specific job titles. However, it is the essential gateway to obtaining a university degree, which unlocks a vast array of professional career paths.

Completing a university degree opens doors to professions such as:

  • Engineer (Civil, Industrial, Computer, etc.)

  • Teacher (Primary or Secondary Education)

  • Healthcare professional (Doctor, Nurse, Pharmacist)

  • Business Administrator / Manager

  • Lawyer / Legal Advisor
