About Sabero
Sabero prepares Colombian students for the ICFES Saber 11 with an AI tutor per question, a personalized coach, and IRT analytics
Sabero is a Colombian platform for ICFES Saber 11 exam preparation. It combines a bank of over 3,000 ICFES-style questions (growing by hundreds of new questions each month) with an AI tutor that explains each answer step by step, a coach that knows the student's history, and analytics based on the same statistical methodology used by the official ICFES: Item Response Theory.
Why Sabero exists
the problem
The same resources as always
Photocopies, YouTube videos, and in-person courses with fixed schedules don't know exactly which topics a student struggles with, and they don't give immediate feedback.

Sabero is founded in Colombia
Instead of measuring performance by percentage of correct answers, Sabero uses Item Response Theory (IRT): the same statistical model the ICFES applies to calculate official scores. Getting a hard question right counts more than getting an easy one right, exactly like the real exam, so any student can identify their exact weaknesses and practice with questions calibrated to their level, whenever they want.

Colombian students take the Saber 11 each period
Their score, on a scale of 0 to 500, determines access to public universities, scholarships like Generación E and Colombia Estudia, and in many cases their professional path for years to come.
