Spaced repetition is a learning technique that helps you remember information by reviewing it at set intervals. This method improves long-term recall, making it easier to retain facts over time.
Research from the National Home Education Research Institute (NHERI) shows that homeschooled students typically score 15 to 25 percentile points higher than public school students on standardized academic achievement tests. Most homeschool families report completing core academic subjects in 3-4 hours per day for elementary students, compared to the 6-7 hours typical of traditional schools, due to the one-on-one instruction and absence of classroom management overhead (NHERI, 2024).
What is spaced repetition?
Spaced repetition is a smart study method that helps you remember things better. Instead of cramming everything at once, you review material just as you're about to forget it. For example, you might look over a new word after one day, then again after three days, then a week, and finally a month. This technique takes advantage of how our memory works. Research shows that spaced repetition is way more effective than cramming for keeping information long-term.
The science behind it
Hermann Ebbinghaus found that without review, we forget about half of what we've learned within days. But every time you recall something, that memory gets stronger. The trick is that actively remembering something helps more than just reading notes. Spaced repetition times your reviews perfectly—challenging enough to make you think, but not so late that you can't remember at all. In one study from 2020, students using spaced repetition scored 70% on tests, while those who crammed only got 64%.
How homeschoolers use it
Many homeschool families set aside 10-15 minutes daily for spaced repetition. It's great for learning foreign language words, math facts, history dates, and more. You can easily mix it into any curriculum. After teaching something new, key facts can go into flashcards for later review. Some families use a physical flashcard system, like the Leitner box method, while others prefer digital tools that automatically schedule reviews. This method works best for subjects that require a lot of facts.
Making it work
The hardest part of spaced repetition is sticking to it. It only works if you review every day; skipping days means you’ll have a big pile of reviews to catch up on. Start with 10-20 flashcards on a subject your child is interested in. Add new cards slowly—it's better to master a small set than to get overwhelmed. For younger kids, parents can make review time a fun game, which keeps it light. You'll see the benefits weeks later when your child remembers facts easily.
The bottom line
Spaced repetition is a proven method for helping homeschool families move facts from short-term to long-term memory. While it doesn’t replace teaching concepts, it solves the retention issue many face. Students who use spaced repetition often find that memorization feels automatic. Information that might have faded after a test stays fresh for years. It takes discipline and daily effort, but for subjects where solid knowledge is key, few methods work as well.
