Side-by-side comparison
IXL Learning vs Khan Academy
A side-by-side from IXL Learning and Khan Academy.
Khan Academy and IXL are the two most-used digital math practice platforms in homeschool, and they get compared constantly. They look similar from the outside — both are screen-based, both are standards-aligned, both cover K–12 — but they're built for different jobs. Khan teaches; IXL drills. Families confusing the two often end up unhappy with whichever one they chose, because they were expecting the other.
Khan Academy is a free 501(c)(3) nonprofit. Short video lessons, practice problems, unit tests, and a mastery progression engine. Coverage is PreK math through Calculus, plus AP courses, SAT prep (with the College Board), some science, history, and reading. The platform is genuinely free with no ads, no upsells, no hidden tiers. Khan is strong as a primary math spine for budget-conscious families and is the default SAT prep tool for college-bound homeschoolers. The trade-off is engagement — kids need to actually watch the videos, which doesn't suit every learner.
IXL is a paid practice and diagnostic platform with 17,000+ standards-aligned skills across math, language arts, science, social studies, and Spanish. Family memberships run $79–$159 per year. The Real-Time Diagnostic is genuinely strong — it identifies a child's working grade level for every strand and surfaces gaps other programs miss. The catch is the SmartScore mechanic: a single wrong answer drops the score significantly, which motivates perfectionists and demoralizes sensitive learners. WellTrainedMind and Cathy Duffy both describe IXL the same way: great for drill, not for teaching.

The verdict
How to choose
Choose Khan Academy if you need a free math spine, you're preparing for SAT/AP, your student can follow video instruction independently, or you want one platform for math, science, and humanities at no cost. Khan is hard to beat at the price.
Choose IXL if you already have a primary curriculum and want a strong diagnostic plus targeted practice, your child is comfortable with the SmartScore mechanic, you need standards-aligned drilling for portfolio or compliance documentation, or your student benefits from gap-finding before moving on. IXL is rarely the right standalone — it's the right complement.
