Homeschooling is legal in all fifty states, but there is no single national homeschool curriculum to buy or follow. Instead you get two things to sort out: your state’s rules, which vary a lot, and your choice of curriculum, which is enormous. The good news is that the academic backbone most curricula are built on, the Common Core and NGSS standards, is free and public. This guide covers your state’s rules, the free standards behind most US curricula, the main types of homeschool curriculum, and how to choose one that your family will actually stick with.
First, check your state’s rules
Homeschool regulation is set state by state and ranges widely. Some states require no notice at all; others ask for an annual notice of intent; and the most regulated require some combination of standardized test scores, portfolio reviews or a set number of instructional days. Your curriculum choice is downstream of this, so start by finding your state’s actual requirements rather than assuming the strictest version applies. In low-regulation states you have almost complete freedom over what and how you teach; in high-regulation states you will want a curriculum that produces reviewable evidence.
The free standards behind most US curricula
Even without a national curriculum, most US states share an academic backbone. The Common Core State Standards define what students learn in Mathematics and English Language Arts from Kindergarten through Grade 12, and the Next Generation Science Standards (NGSS) do the same for Science. Both are free to read online, and between them they cover the three subjects where sequence matters most.
Most states use Common Core or standards closely derived from it, and NGSS has been adopted or adapted by a large majority of states. The notable holdouts write their own: Texas uses the TEKS and Virginia uses its Standards of Learning. Even in those states, a well-built fractions or forces lesson is the same content, so you can treat the standards as a checklist and confirm against your state’s framework. Our overview of which curriculum your state uses goes into more detail.
The main types of homeschool curriculum
“Homeschool curriculum” covers everything from a full boxed program to a teaching philosophy. The main options:
- Boxed or all-in-one programs. Everything scripted and sequenced across subjects. The most hand-holding, and usually the most expensive. Available in both secular and faith-based versions, so check which you are buying.
- Online programs and virtual schools. Lessons delivered and often graded online, ranging from free public options in some states to paid private academies.
- Philosophy-based approaches. Classical (grammar, logic, rhetoric stages), Charlotte Mason (living books and narration), Montessori (hands-on, self-directed) and unit studies (one theme across several subjects). These describe a method more than a boxed product.
- Unschooling. Child-led learning with no fixed curriculum, legal in most states but harder to evidence where portfolio reviews are required.
- Eclectic. What most experienced families actually do: a strong math and reading spine, borrowed from wherever fits, with content subjects taught by interest. This is usually the cheapest and most durable option.
How to choose one
The most common and most expensive mistake is buying a full boxed curriculum in the first nervous month, then abandoning it by October. Choose in this order instead:
- Start from the free standards for Math, ELA and Science so you know the destinations, whatever wrapper you add later.
- Match the amount of structure to you, not to an ideal. A parent who wants nothing to plan should buy more structure; a parent who likes to teach can spend far less.
- Prefer secular or faith-based deliberately rather than by accident, because it is baked deep into many US programs.
- Pick something that produces evidence if your state requires reviews: dated work samples, and lessons that record the standard they covered.
- Above all, pick something this particular child will finish over something that merely looks rigorous.
Using your curriculum well
Whatever you choose, the standard stays fixed while the wrapper is free to change. The Grade 3 standard on multiplication does not care whether the problems are about Minecraft, baseball stats or baking, so teach it through what your child already loves. Keep math and reading short and daily, teach the content subjects by topic, and use practice that checks itself so you are the encourager sitting alongside rather than the grader across the table, the approach behind why personalized lessons help students learn faster.

Sprout Lessons is built for this. Pick United States (Common Core + NGSS), a grade and a topic, describe your child’s interests in a sentence, and get back an interactive lesson with worked examples and self-checking practice, with each standard code (like CCSS.MATH.CONTENT.3.OA.A.1 or MS-PS1-2) recorded in the footer so it drops straight into your homeschool records. There is more on how the alignment works in how Sprout supports Common Core and NGSS.
You do not need to spend hundreds of dollars to homeschool well in the US. Check your state’s rules, start from the free standards, choose the amount of structure that fits your family, and teach through what your child cares about. Try Sprout free: new accounts start with free lessons, and your first standards-aligned lesson takes about a minute.
FAQ
What is the best homeschool curriculum in the US?
There is no single best one, because it depends on your state’s rules, how much you want to plan, and whether you want secular or faith-based content. For most families the most durable and affordable route is eclectic: a strong math and reading spine built on the free Common Core standards, with content subjects taught by interest. Boxed programs suit families who want everything scripted, especially in a first year.
Is there a free homeschool curriculum in the US?
Yes. The Common Core standards for Math and English Language Arts and the Next Generation Science Standards for Science are free and public, and some states offer free online public-school-at-home programs. Between the free standards, the library and free institutional material, families can cover the whole curriculum without buying a boxed program.
Do homeschoolers have to follow Common Core?
No. Homeschoolers are generally free to choose their own curriculum, and Common Core is a set of standards rather than a mandated curriculum. Most states use Common Core or standards derived from it, so aligning to it keeps you close to what schools teach, but Texas (TEKS) and Virginia (Standards of Learning) write their own, and many families deliberately use classical, Charlotte Mason or other approaches instead.
What are the main types of homeschool curriculum?
Boxed or all-in-one programs (everything scripted), online programs and virtual schools, philosophy-based approaches (classical, Charlotte Mason, Montessori, unit studies), unschooling (child-led, no fixed curriculum), and eclectic (a mix, which is what most experienced families settle into). Each also comes in secular and faith-based versions, so that is a separate choice to make on purpose.
