It is a Saturday morning in October, eighteen months into running your microschool. You are standing in front of the supply closet trying to figure out where to put the new science workbooks that arrived on Thursday.
The shelf already holds Singapore Math 2A and 3B, a Classical Conversations memory work guide for Cycle 2, three volumes of Story of the World, a Charlotte Mason nature journal curriculum you bought at a conference in April, a phonics program your kindergartner's family brought from their previous co-op, and a set of Notgrass history books you ordered last spring when you felt the history spine wasn't holding.
You have two history programs. You might have a writing program — you are not entirely sure. Math is solid, except you have no plan for what comes after Singapore 5B. The phonics program does not connect to anything else you own.
Nobody told you curriculum selection would produce this. The advice was: define your educational philosophy, then choose materials that align with it. You defined your philosophy. You chose materials. Somehow you ended up with a closet full of programs that do not know each other exist.
This is not a philosophy problem. It is an architecture problem.
The Three Ways a Curriculum Stack Breaks Down¶
Most microschool founders make curriculum decisions in isolation — one program at a conference, one after a struggling student, one after a parent recommendation. Those decisions are usually good ones. The problem is not the individual programs. It is that the stack was never designed as a stack.
The result is one of three failure modes:
Gaps. Subjects that have no systematic home. Writing is the most common orphan — founders often have a strong math program, a history spine, a science rotation, and then realize in December that they have no explicit writing program, just "writing that happens inside other subjects." Composition skills, grammar, and the mechanics of constructing an argument are being taught by accident, if at all.
Overlaps. Two programs covering the same content without coordinating. Running Story of the World alongside Notgrass American History means students may hear about the same time period twice in one year, or encounter the same primary source in two different contexts with no bridge between them. Some redundancy is healthy. Unplanned redundancy is time that could go somewhere it is needed.
Conflicts. Programs with incompatible assumptions about how children learn. A mastery-spiral math program (Saxon) assumes students revisit the same concept repeatedly across months. A unit-study approach to writing assumes depth over one extended project. When these sit alongside a Charlotte Mason philosophy that resists drilling, the classroom develops a persistent low-level friction — the teacher knows something does not feel right but cannot name what.
Finding and fixing these three failure modes is the actual work of curriculum selection. The philosophy question matters, but it comes first, not last.
Step 1: Map Your Philosophy to Each Subject Separately¶
The standard advice — pick Montessori or classical or Charlotte Mason and then find curriculum that matches — assumes your philosophy is a monolith. It rarely is.
Most working microschools use something closer to a subject-level philosophy: rigorous and sequential for math, inquiry-based for science, literature-heavy and narrative for history, mastery-based for foundational reading. These are not contradictions. A child can drill multiplication facts in the morning and spend the afternoon doing nature observation journaling. The methods fit the subject.
Before auditing what you own, write down what you actually believe about how children learn each of the following:
| Subject | Your core assumption about how kids learn it |
|---|---|
| Math | Sequential mastery? Spiral review? Conceptual-first? Procedural fluency? |
| Reading / Phonics | Systematic phonics? Whole-language immersion? Phonics-to-fluency pipeline? |
| Writing / Composition | Structured models (IEW, Writing & Rhetoric)? Process writing? Narration-based? |
| History | Narrative spine? Primary sources? Chronological rotation? Living books? |
| Science | Textbook sequence? Unit studies? Lab-inquiry-first? Nature study? |
| Literature | Great Books? Living books? Student-choice reading? Read-aloud spines? |
| Logic / Reasoning | Formal logic (Fallacy Detective, Traditional Logic)? Socratic discussion? Implicit in everything? |
This exercise takes about twenty minutes and produces something more useful than any philosophy label: a map of what you actually want, subject by subject. That map is what you audit your existing programs against.
Step 2: Run the Curriculum Audit¶
With your philosophy map in hand, go through every program you own or currently use. For each one, answer four questions:
- What subject does this program own? (Be specific: "phonics through decoding fluency" is more useful than "reading.")
- What grade level or skill range does it cover?
- Does it match your stated philosophy for that subject?
- What does it assume students know coming in, and where does it leave them going out?
That last question — the entry and exit state — is the one most founders skip. It is the question that reveals whether your programs connect.
After the audit, you are looking for three things:
Blank rows. If a subject has no program, that is a gap. Writing and formal grammar are the most common blank rows. Logic is nearly always blank until middle school, which is fine — but worth noting.
Double rows. Two programs claiming the same subject for the same age range. Decide which one leads and which one supplements, or consolidate.
Exit-entry mismatches. Program A ends at a point that does not cleanly connect to the program you want to use next. This is common in math: Saxon 8/7 exits at a different place than where Saxon Algebra 1 wants students to start, which catches founders off guard after years of smooth progression. The same thing happens when switching from one reading program to another mid-phonics sequence.
Step 3: Check the Scope-and-Sequence Connections¶
A curriculum's scope and sequence is the document that lists what students are expected to know by the end of each level and what they need to know coming in. Most programs publish this, though it is sometimes buried.
The scope-and-sequence check answers one question: if a student finishes Program A in June, are they ready for Program B in September?
This matters most in two situations:
Switching programs mid-sequence. If you started Singapore Math and are considering a switch to Math-U-See at level 4, the exit state of Singapore 4B does not map cleanly to the entry state of Math-U-See Gamma. There is content that Singapore covers in books 1-4 that Math-U-See structures differently. A placement test for the incoming program is not optional — it is the bridge.
Multi-age rooms where students enter at different points. A student who joins your microschool in January having used Abeka phonics for two years is not at the same point in their phonics sequence as a student who has been working through All About Reading. They may be at the same instructional level. They are not at the same program entry point. Knowing the exit state of the incoming student's prior program tells you where to place them in yours.
For history, literature, and science — subjects where the content is less strictly sequential — the scope-and-sequence check is simpler: just confirm that your four-year rotation (if you use one) does not have two years of the same period and skip another entirely.
Step 4: Solve the Record-Keeping Problem Before You Add Anything New¶
Here is the part most curriculum planning guides skip entirely.
A multi-provider curriculum stack creates a gradebook nightmare. Saxon Math uses a numerical score on daily lessons and tests. Charlotte Mason-influenced curricula are assessed through narration and observation notes, not scores. Classical Conversations measures memory work mastery through a completely different rubric. A student working through IEW for writing produces a portfolio of drafts. Your science program may use lab reports. Your history program may have chapter tests.
You have six programs. You have six different ways of recording progress. When a parent asks "how is she doing in writing?" you have a folder of rough drafts and a memory of Tuesday's narration. That is not a record. It is not a transcript entry. And at the end of the year, when you need to document that this student completed a coherent second-grade program, the documentation lives in six different places in six different formats.
The solution is not to standardize how each program records progress — that would require changing the programs. The solution is to choose one central place where each program's evidence gets translated into your school's records.
The central tracking system does not need to be sophisticated. It needs to be consistent. You need one place — a spreadsheet, a dedicated gradebook app, or a school management system — that accepts input from all your programs without requiring them all to use the same format. What matters is not which tool you choose. It is the habit: deciding what counts as a record for each program and entering it at a regular interval.
In practice, that means:
- Deciding what counts as a "grade" for each program (a test score, a rubric score, a completion check, a narrative note)
- Entering it in one place at a consistent interval (weekly works better than end-of-term)
- Keeping the raw evidence (the test, the narration recording, the portfolio draft) as the backup
Solve the record-keeping architecture before you add any new programs. Adding a fourth program to a stack that already has no coherent tracking system makes the tracking problem worse, not better.
Four Curriculum Stack Models That Actually Work¶
After the audit, you are either confirming that your existing stack is coherent or rebuilding it. Either way, it helps to know what a functional stack looks like. Here are four models that hold up in practice.
The Spine + Supplement Model¶
One program serves as the backbone of the academic year — setting the chronological framework, the vocabulary, the major themes. Everything else supplements it.
The most common implementation: The Well-Trained Mind or Classical Conversations as the spine for history and literature, with independent programs for math (Saxon or Singapore), phonics (All About Reading or Logic of English), and writing (Writing & Rhetoric or IEW). The spine provides coherence across the humanities; the independent programs provide rigorous sequence in skills subjects.
Works well for: Classically-oriented founders who want a clear anchor for the school year.
Watch for: Supplements multiplying over time until they are no longer supplements — they are a second spine. Audit annually.
The Core + Enrichment Model¶
One all-in-one program covers core academic subjects; everything else is enrichment layered on top.
Common implementations: Blossom & Root, My Father's World, or Sonlight as the core, with additional math from Singapore or Math Mammoth and enrichment in art, music, and nature study. Works particularly well for the K–4 range, where integration across subjects is developmentally appropriate.
Works well for: Founders who want a low-planning daily flow, especially in the early years.
Watch for: The core program becoming a constraint when students outgrow it, arrive at different stages, or when the all-in-one scope does not match what the founding family needs for a particular student.
The Mastery-Sequence Model¶
Each subject has exactly one program, chosen because its scope and sequence is complete from entry to exit. The programs do not need to talk to each other — they just need to cover the subjects without gaps.
Common implementations: All About Reading + All About Spelling for language arts foundational skills, Saxon Math from K through pre-algebra, a separate history rotation (Notgrass or Story of the World), and a lab-based science program. Each program owns its subject completely.
Works well for: Founders who want predictable, measurable progression and clear scope across the year.
Watch for: Rigid pacing that does not accommodate the natural variability of a multi-age room. A student who enters at an unexpected point in one program will not enter at the right point in the others.
The Portfolio / Project Model¶
No prescribed sequence. Unit studies, project-based learning, and interest-led inquiry are the primary vehicle. Formal programs are used selectively for skills that require explicit instruction (phonics, arithmetic facts) but do not anchor the school calendar.
Works well for: Project-based schools, nature-immersion programs, and founders working with a small group of older students (grades 5 and up) who can sustain extended project work.
Watch for: Gaps in foundational skills. If the only systematic phonics instruction is "reading happens inside the projects," some students will miss phonics patterns they needed explicitly taught. Portfolio models work well for inquiry-driven content knowledge; they require deliberate supplementation for skills-based subjects.
The One-Hour Curriculum Audit¶
This is the actual process. Set aside an hour. Bring your materials list or walk the shelf.
Phase 1: Inventory (20 min)
List every program you own or currently use. For each one, record:
| Program | Subject | Grade range | Grades used? | Entry assumption | Exit state |
|---|---|---|---|---|---|
| Singapore Math 3B | Math | Grade 3 | Y | Mult./division fluency | Fractions, decimals intro |
| All About Reading 2 | Phonics/decoding | Late grade 1–2 | Y | Letter sounds mastered | Multisyllable words, fluency |
| Story of the World Vol. 1 | History | Grades 1–4 | Y | None | Ancient history survey |
| (add your programs) |
Fill this in for everything on your shelf, including programs you bought but have not started.
Phase 2: Gap analysis (15 min)
Check which subjects have no row:
- Writing / composition
- Grammar
- Spelling
- Vocabulary
- Logic / critical thinking
- Art, music, physical education (flag these separately — they are often intentionally informal)
Any blank that is not intentional is a gap to address.
Phase 3: Overlap and conflict analysis (15 min)
Highlight any subject with more than one row. For each double row:
- Is the overlap intentional and complementary, or is it an accident?
- Which program leads? Which supplements?
- If there is a philosophical conflict (one program drills, one program forbids drilling), decide which philosophy wins for that subject.
Phase 4: Scope-and-sequence connections (10 min)
For each program: what does a student need to know to start it, and where does it leave them? Does the exit state of the program connect to whatever you plan to use next?
If you do not know the answer to that question for a program you are using, look up the scope-and-sequence document before this week is out.
When to Swap Versus Patch¶
After the audit, you will face one of two situations.
Patch: Your stack is mostly coherent but has a specific gap or mismatch. Add the minimum program needed to close the gap. A microschool that has everything except a writing program needs one writing program, not a philosophy overhaul.
Swap: A program is genuinely not working — students are not making progress, the philosophy conflict is real and persistent, or the scope-and-sequence exit does not connect to anything you want to use next. In that case, pick the replacement before discontinuing the current program, run them simultaneously for one semester as you determine placement, and document the transition in each student's record.
The most common mistake is solving a swap problem with a patch. If Singapore Math is generating persistent frustration because your teaching approach is more mastery-based and less spiral, adding a second math program does not fix the problem — it adds work. The problem is a swap. Make the swap.
What to Tell Parents About Your Curriculum Choices¶
Parents who enroll in a microschool often ask: "What curriculum do you use?"
The honest answer — "we use a combination of programs" — can sound evasive even when it is the right one. Here is how to explain it in a way that builds confidence rather than questions.
Frame it as intention, not improvisation. The fact that you use multiple programs is a feature, not a compromise. A single all-in-one curriculum assumes that one philosophy, one pacing structure, and one assessment approach will serve every subject equally well for every student. Subject-level curriculum selection is a deliberate pedagogical choice.
Name the programs and the reasons. "We use Saxon Math because we believe in procedural fluency built through daily distributed practice. We use All About Reading because it provides systematic, explicit phonics instruction from decoding to fluency. We use Story of the World as our history spine because it gives us a consistent narrative framework across four years." That is a credible answer. It demonstrates intention. Most parents are reassured not by the name of the program but by the evidence that you chose it on purpose.
Show parents the record. The best evidence that your multi-curriculum approach is coherent is a consistent, readable student record. A parent who can see their child's progress across subjects — even across different program types and formats — has the documentation they need that the school has a plan.
If you have built the record-keeping architecture before enrollment, this conversation is easy. If you have not, the question "what curriculum do you use?" will be the first symptom of a stack that was assembled without a plan.
The goal is a coherent stack, not a complete collection¶
Curriculum selection anxiety drives founders to acquire. The conference vendor booth is not your friend in October when you have just run the audit and found two gaps. The gaps are real. But the right response is one careful addition per gap, not three programs that might address it.
A coherent stack of five programs that connect, cover the subjects without gaps, and generate records you can actually use is more educationally sound than a shelf of twenty that were each individually excellent when you bought them.
You already built the school. You can build the stack.
Track student progress across every curriculum you use — from Saxon test scores to Charlotte Mason narration notes — in one place.

Frequently Asked Questions¶
Can I use more than one math program at the same time?
You can, but be deliberate about why. The most functional dual-math arrangement is one program for conceptual development (Math-U-See, RightStart) and one for fluency practice (Khan Academy, Xtra Math). If both programs are covering the same content at the same level, you are doubling your prep without doubling the learning.
How do I handle students who arrive having used a completely different curriculum?
Use a placement test for the receiving program, not the student's prior grade level. Most established programs publish placement tests. The test tells you the student's entry point in your program's sequence, which is what you actually need to know. Their prior grade is a starting hint, not a placement decision.
How often should I audit my curriculum stack?
Once per year, ideally in June or July. After the first year, most stacks are relatively stable — you are adjusting one or two programs, not rebuilding. The audit is also a useful moment to update student records so the summer gap does not make fall record-keeping harder.
What if my philosophy genuinely does not match any published curriculum?
It happens more than the curriculum companies would like. The practical answer: use a published program for foundational skills subjects where explicit sequence matters (phonics, arithmetic, writing mechanics) and build your own approach for content subjects (history, science, literature) where the sequence is more flexible. This is already what most microschool founders are doing, often without realizing it.
Do I need a different curriculum for each age in a multi-age room?
For content subjects (history, science, literature), often not — a well-chosen spine works across a wide age range with differentiated discussion. For skills subjects (math, phonics), yes: students work at their own level, which usually means different programs or different levels of the same program. See our post on grading in a multi-age classroom for how to handle assessment when students are at different levels.
