All-in-One Homeschool Curriculum: Complete K–12 Programs Compared

You want to open a box, take out a schedule, and know exactly what to do every day. That's a legitimate and reasonable thing to want, especially in your first year of homeschooling. All-in-one and full curriculum packages exist precisely for this reason.

The problem is that "all-in-one" means different things to different publishers. Some sell a complete, scripted, multi-subject curriculum that covers every subject for one grade level. Others sell a catalog of individual subject programs and call them a "curriculum." The distinction matters enormously when you're comparing prices and trying to understand what you're actually getting.

Here's a real comparison of the major all-in-one and full K–12 homeschool programs.

What to Look for in a Complete Curriculum Package

A genuinely complete all-in-one curriculum should cover, at minimum: math, language arts (reading and writing), history or social studies, and science. For elementary grades, it should also address phonics, handwriting, and beginning grammar. For high school, it needs to provide credit documentation.

Beyond coverage, the key variables that determine fit:

• Worldview: Is it explicitly Christian, faith-neutral, or secular? This is the single biggest filter.
• Teacher prep time: Is it "open and go" (scripted lessons, no prep required) or teacher-intensive (requiring parent preparation and creativity)?
• True cost: Not the advertised price, but the total cost including consumable workbooks, teacher guides, required manipulatives, and shipping.
• Digital vs. physical: Online programs eliminate shipping but require screens. Physical programs feel more tangible but require storage and repurchasing consumables each year.

All-in-One Programs: The Main Options

Abeka (Christian, K–12)

Abeka is the largest explicitly Christian homeschool curriculum publisher in the US. Its materials are used by both traditional Christian schools and homeschooling families. The curriculum is textbook-based, academically rigorous by traditional standards, and integrates Biblical content throughout every subject.

Philosophy: School-at-home. Replicates a traditional Christian school environment at home. Structured, textbook-driven, with tests and grades.

Worldview: Young Earth Creationist in science. Providence-oriented history. Scripture integrated into every subject including math.

Cost: Full grade-level homeschool kits range from approximately $450–$800 per year, depending on grade and whether you choose physical books, DVD instruction, or online. Abeka's DVD/Academy option (video instruction) can reach $1,000+ per year.

Teacher prep time: Low once you understand the system. Lessons are scripted in teacher manuals.

Best for: Families who want rigorous academic work in a clearly Christian framework and are comfortable with a school-at-home model.

Worth knowing: Abeka is academically ahead of public school grade level in many subjects, which is a feature for some families and a source of overwhelm for others.

BJU Press (Bob Jones University Press)

Similar to Abeka in structure and worldview — explicitly Christian, textbook-based, academically rigorous. BJU Press is considered slightly more engaging in presentation than Abeka and is widely used in Christian co-ops.

Cost: Similar to Abeka — approximately $400–$700 per grade level. BJU Homeschool video instruction option also available.

Best for: Families wanting high academic rigor in a conservative Christian framework with strong science and math coverage.

Sonlight (Christian, K–12)

Sonlight uses a literature-based approach (Charlotte Mason-influenced) with a Christian worldview. The "Instructor's Guide" provides a complete 36-week schedule telling you exactly what to read, when, and what questions to ask. It's the closest thing to a scripted, Charlotte Mason-compatible curriculum package.

Philosophy: Charlotte Mason / literature-based. Heavy on read-alouds, living books, and narration. Includes history, science, language arts, and Bible. Math sold separately.

Cost: Core programs run $270–$800+ depending on grade level. Math is always an additional purchase. This is one of the most expensive all-in-one options.

Teacher prep time: Moderate. The Instructor's Guide does most of the planning, but the read-aloud-heavy format requires parental presence.

Best for: Families who love reading and want a structured, literature-rich curriculum with Christian worldview. Not suitable for parents who want a truly hands-off, self-paced program.

Note: Sonlight is notably multicultural in its book selection, including histories and stories from non-Western cultures, which distinguishes it from other Christian programs.

My Father's World (MFW)

Another Christian all-in-one, MFW blends Charlotte Mason and classical approaches with explicit Biblical integration. Programs run PreK through high school. The curriculum cycles through world history over six years in elementary.

Cost: Approximately $150–$350 per year. More affordable than Sonlight for similar literature-based content.

Best for: Families who want Charlotte Mason methods with strong Christian faith integration at a lower price point than Sonlight.

The Good and the Beautiful (TGAB)

A rapidly growing curriculum built on aesthetically beautiful materials, Charlotte Mason methodology, and a broadly Christian worldview. Available in print (at cost) or as free PDF downloads. The founder of the curriculum is a member of The Church of Jesus Christ of Latter-day Saints, which matters to some Evangelical families.

Cost: PDFs are free. Print versions are approximately $25–$90 per level. This makes TGAB one of the most affordable complete programs available, which explains its rapid growth.

Teacher prep time: Low. "Open and go" for most levels.

Best for: Budget-conscious families comfortable with broadly Christian content who prefer aesthetically rich materials.

Controversy: The LDS faith of the founder leads some Evangelical Christians to avoid the curriculum despite the content being broadly "mere Christian." This is a personal decision that each family must make.

Bookshark (Secular, K–12)

Bookshark is Sonlight's secular sister curriculum. Same structure, same Instructor's Guides, same literature-based approach — but with no Bible, creationism, or explicitly religious content. This makes it one of the only truly complete, literature-based all-in-one options for secular families.

Cost: Similar to Sonlight — $250–$700+ per core program. Math sold separately.

Best for: Secular families who want the structure and literature-richness of Sonlight without the religious content.

The secular gap note: Most of the truly "all-in-one" complete programs in the homeschool market are Christian. Secular families looking for a single package often find Bookshark or Timberdoodle as their strongest options, and are more likely to patchwork programs subject by subject.

Timberdoodle (Secular-Friendly, K–8)

Timberdoodle sells curated grade-level kits rather than a single publisher's curriculum. Each kit bundles best-in-class resources from multiple publishers into a cohesive package for one grade level. The result is a curated, multi-publisher all-in-one that tends to be more hands-on and manipulative-heavy than single-publisher options.

Cost: Approximately $300–$700 per grade level depending on grade and customization. You can swap individual items in or out.

Best for: Families who want a secular-friendly, hands-on package without assembling it themselves. Also strong for learning-different children, as kits can be mixed across grade levels.

Time4Learning (Digital, K–12)

A fully online program covering all core subjects with automated grading and progress tracking. Works for both homeschool and afterschool use.

Cost: Approximately $30 per month for one student (K–8); $35/month for high school.

Best for: Parents who need a fully hands-off, self-pacing digital program. Popular for children who prefer screens to textbooks, or families using it as a transitional program during deschooling.

Limitation: Not as rigorous as Abeka or BJU Press academically. Often described as working "one grade below" typical school pace.

The True Cost Comparison

Published prices are misleading because: - Consumable workbooks must be repurchased each year for additional children - Manipulatives (Math-U-See blocks, hands-on kits) are upfront purchases not reflected in "grade level" pricing - Shipping costs for large physical curriculum orders can add $35–$75 per order - Some programs require separate teacher's manuals, answer keys, and test booklets

The United States Curriculum Matching Matrix breaks down the true system cost — total first-year cost including all required purchases — for every major all-in-one program alongside their worldview designation, prep time rating, and learning style compatibility. If you're trying to make a final decision between Sonlight, Bookshark, and Abeka, having those variables side by side in one place saves hours of cross-checking individual publisher websites.

The right all-in-one curriculum is the one that matches your worldview, your child's learning style, your budget, and — critically — your own teaching bandwidth. A beautifully curated program you can't sustain isn't better than a simpler one you'll actually use every day.
