Choosing a homeschool curriculum by grade can feel overwhelming, especially when so many popular programs weave religious content into their lessons. If you are a family looking for science-based, academically rigorous materials without religious framing, you are far from alone — and you have more options today than ever before.

Since 2020, the number of homeschooling families in the United States has more than doubled. A significant portion of that growth has come from non-religious households who want greater control over their children's education without sacrificing academic quality. Curriculum publishers have responded. The evidence-based homeschool market has expanded rapidly, and today you can find strong, well-reviewed options for every grade level and every subject.

This guide walks you through the best evidence-based homeschool curriculum picks from PreK through 12th grade, highlights standout programs for key subjects, and breaks down your options by budget so you can build the right plan for your family.

What Makes a Curriculum "Evidence-Based"?

Before we dive into grade-level picks, a quick note on what we mean by evidence-based in this context. An evidence-based, non-religious curriculum:

Teaches science using peer-reviewed content (evolution, earth science, climate science presented as established science)
Covers history and social studies without a religious worldview filter
Does not include Bible verses, devotions, or faith-based character lessons woven into academic content
Presents world religions and cultures from an informational, not devotional, perspective

Some programs marketed as "neutral" still slip in religious undertones. The picks in this guide have been vetted to be genuinely free of religious content.

Homeschool Curriculum by Grade: Your Grade-by-Grade Breakdown

PreK Through 2nd Grade (Ages 4-8)

The early years are all about building a love of learning. At this stage, you do not need a rigid, expensive packaged curriculum. Focus on reading aloud, hands-on exploration, and play-based math.

Top picks for PreK-2:

BookShark Level K-2 — A complete, literature-based curriculum that uses real books instead of textbooks. Science and history are woven into engaging read-alouds, and every component is non-religious by design. BookShark is one of the few all-in-one packages where you do not need to swap out individual pieces.
Beast Academy (Math) — From the creators of Art of Problem Solving, Beast Academy teaches math through comic-style instruction and challenging puzzles. It builds deep conceptual understanding and is far more engaging than traditional worksheets.
The Good and the Beautiful Language Arts (Free Levels) — Several levels of their language arts program are available for free download. While the company has religious roots, their language arts materials are content-neutral and widely used by many homeschool families.

Practical tip: At this age, your local library is your greatest resource. Pair any structured curriculum with a weekly library trip and you have a rich, low-cost program.

3rd Through 5th Grade (Ages 8-11)

This is where many families start looking for more structured programs. Kids are reading independently and ready for deeper content in science and history.

Top picks for grades 3-5:

BookShark Levels 3-5 — Continues the literature-based approach with more complex novels and nonfiction. The history and science reading lists at these levels are genuinely excellent. If you want a full program that covers language arts, history, and science in one package, BookShark remains a strong choice.
Singapore Math / Dimensions Math — Widely considered one of the strongest elementary math programs in the world. Uses a concrete-pictorial-abstract approach that helps kids truly understand math instead of just memorizing steps. Completely evidence-based.
BFSU (Building Foundations of Scientific Understanding) — A parent-led science program that teaches through hands-on experiments and discussion. It follows the way scientists actually think rather than just presenting facts to memorize.

Practical tip: Grades 3-5 is an ideal time to add a video-based supplement for subjects where your child wants more depth. Compass Classroom offers well-produced video courses in science and other subjects that work well alongside a core curriculum.

6th Through 8th Grade (Ages 11-14)

Middle school is when many families transition to more independent learning. Your child can begin handling some subjects with less direct instruction, which opens up options that combine textbook or video lessons with self-paced work.

Top picks for grades 6-8:

BookShark Levels 6-8 — The reading lists become genuinely compelling at this level, with novels and nonfiction that cover world history, American history, and science topics in depth. Many families credit BookShark with turning reluctant readers into kids who actually enjoy their assignments.
CK-12 (Free) — A completely free, online textbook platform with interactive content for math, science, and more. The materials are created by educators and the platform is entirely non-religious. An outstanding option for families on a tight budget.
Outschool — Live, online classes taught by vetted instructors. Outschool is not a curriculum itself, but it fills gaps brilliantly. Need an evidence-based biology class or a writing workshop? You can find one here, and your child gets the social interaction of a classroom setting.

Practical tip: Middle school is the right time to start thinking about high school transcript requirements if your state has them. Keep records of what your child studies and any grades or portfolio pieces from this stage forward.

9th Through 12th Grade (Ages 14-18)

High school is where curriculum choices carry real weight. Colleges look at course rigor, and many families want programs that provide official transcripts or align with standard high school coursework.

Top picks for grades 9-12:

Compass Classroom — Their video-based courses cover science, economics, and other high school subjects with professional-quality production. For families who want a teacher-on-screen experience without religious content, Compass Classroom is one of the best options available.
Derek Owens (Math and Science) — Video-based math and physics courses with problem sets, grading, and transcript-ready records. Derek Owens courses are used by many homeschool families for high school credits.
Dual Enrollment — Not a curriculum, but a strategy. Many homeschool students begin taking community college courses during 11th and 12th grade. These courses count for both high school and college credit, save money on tuition, and are inherently academically rigorous.

Practical tip: For high school, consider mixing and matching. Use a strong math program, a video-based science course, a literature reading list you curate yourself, and community college for one or two electives. You do not need a single publisher to cover everything.

Subject Spotlights: Where Evidence-Based Options Really Shine

Science — The Standout Category

Science is the subject where the difference between evidence-based and religious curriculum is most dramatic. Evidence-based science programs teach evolution as established science, cover the geological timeline accurately, and present climate science without hedging. Top picks include Real Science Odyssey, Elemental Science, and the BFSU series mentioned above. For high school, look at Novare Science or Compass Classroom's science courses.

History — Context Without a Worldview Filter

Evidence-based history programs present events, cultures, and civilizations without framing them through a religious narrative. BookShark's history components are particularly strong here, presenting world history through diverse literature rather than a single-perspective textbook. Story of the World by Susan Wise Bauer is another popular option — it is written from a neutral perspective and covers ancient through modern history across four volumes.

Language Arts — Plenty of Strong Options

Language arts is the easiest subject to keep academically focused because most reading and writing programs focus on skills rather than content. Programs like Logic of English, All About Reading (for younger kids), and Michael Clay Thompson's language arts series are all well-regarded and content-neutral.

Budget Tiers: Finding the Right Curriculum at Every Price Point

Free and Low-Cost (Under $100/year)

You can build a solid, evidence-based education without spending much at all:

Khan Academy — Free math, science, and more. Self-paced with built-in practice and mastery tracking.
CK-12 — Free online textbooks and interactive content for multiple subjects.
Ambleside Online — A free Charlotte Mason curriculum guide with non-religious modifications available from the community.
Your public library — Free access to books, audiobooks, and digital resources. Many libraries also offer free museum passes and educational programs.

Mid-Range ($100-$500/year)

This is the sweet spot for most families. You can buy one or two strong core programs and supplement the rest for free:

A full BookShark level runs roughly $300-$500 depending on the package and covers language arts, history, and science with real books. Math is separate.
Singapore Math workbooks cost around $30-$50 per year.
Add Khan Academy or CK-12 for free supplemental content and you have a comprehensive program for under $500 total.

Premium ($500+/year)

If your budget allows, premium options give you the convenience of everything planned, scheduled, and ready to go:

Full packaged programs with all subjects, teacher guides, and materials included
Video-based courses like Compass Classroom for subjects where you want a teacher handling instruction
Live online classes through Outschool or similar platforms for social interaction and specialized subjects

The bottom line on budget: You do not have to spend a lot to homeschool well. The best curriculum is the one your child actually engages with. Start with free resources, add one or two strong paid programs where they matter most (usually math and reading for younger kids, or science and math for older students), and build from there.

Putting It All Together

Choosing a homeschool curriculum by grade does not have to be complicated. Here is a simple framework:

Identify your must-haves. Which subjects need a structured, purchased program? Which can you handle with library books and free online resources?
Match the format to your child. Some kids thrive with textbooks. Others need video instruction, hands-on projects, or literature-based learning. Pick the format that fits, not the one that looks most impressive.
Start with one grade band. Do not try to plan kindergarten through 12th grade on day one. Pick the best options for where your child is right now and adjust each year.
Use this guide as a starting point. Read reviews from other homeschool families. Join a like-minded homeschool community online. Ask what is working for families with kids similar to yours.

The homeschool landscape for evidence-based families is better than it has ever been. Whether you are just starting out or switching from a program that was not the right fit, there is a curriculum out there that will work for your family — no compromises on your values, no gaps in academics.
