McGraw Hill deployed ALEKS, an AI-powered adaptive learning platform for math and chemistry, which assesses each student's knowledge and builds a personalized learning path to fill gaps and guide mastery.

ALEKS (Assessment and LEarning in Knowledge Spaces) is built on Knowledge Space Theory and has used AI, including machine learning, for over 25 years. It assigns students periodic mini-assessments called Knowledge Checks to determine exactly what they know and what they are ready to learn next, then delivers a dynamic, individualized content path. In 2023, McGraw Hill added deep learning neural networks to ALEKS, reducing time students spend on assessments by more than 20% while improving learning outcomes. ALEKS serves K–12 through higher education in math and chemistry subjects, with ALEKS for Calculus released in September 2025.
