What Sets Our Adaptive Academic Learning Resources Apart
Tools to help you focus on what matters. Personalize learning for each student. Align to standards with just one click. Let our platform do the work of adapting in real time, so you can focus on the important stuff: helping your students succeed.
Our adaptive platform delivers continuously personalized enrichment, scaffolded support, and mastery to every student, and our enhanced curriculum can be customized with a simple drag-and-drop. Even better, our classroom assessments and curated open education resources are now part of the same learning package—saving you time, money, and hassle.
We’re people-focused, not tech-led. We make online learning meaningful because our curated resources provide custom learning paths for each student, putting your kiddos at the center of all we do. And our ready-made curriculum offers more than 1000 standards-aligned and textbook-mapped adaptive learning paths in math and English language arts—all made by people who care about education as much as you.
