Choosing curriculum is one of the highest-stakes decisions a family makes, and most of the information out there is either marketing or a popularity contest. So we built a standard, published it, and hold every curriculum to the same one. This page explains exactly what we measure and how, so you can decide whether you trust the rating.
Every curriculum is scored against the same nine dimensions. What differs is who is doing the looking.
Our reviewers score each dimension against evidence they can inspect: the published scope, sample lessons, assessments, the parent or teacher materials, pricing and policies. The rubric is validated by a certified teacher. Every score of the highest or lowest kind has to carry a source.
Verified, certified educators score the same nine dimensions from real classroom and homeschool experience, and add written feedback about what worked and what did not. Contributions are collated and anonymous, so a teacher can be honest without being named. This rating grows as the Alliance grows.
Neither rating is a vote count, an endorsement, or a promise about how any individual child will do. Each is shown for a stated use, because the same curriculum can be a poor core program and an excellent supplement.
Each is scored on a five-point reviewer scale. On every curriculum page you can see how it scored on all nine, so a strong overall rating can never hide a weak spot.
Is the content accurate, at the right level, and does it cover what it claims?
We read the actual scope and sequence, student samples and assessments rather than the marketing page, and we look for credible outside validation. For a school that means accreditation, an AP audit, NCAA approval or state adoption. For a publisher, which cannot hold those, it means sustained independent expert review or approval by schools and districts that vetted it with money on the line.
Does it build in a sensible order and make a student actually think?
Strong material accumulates. Each unit rests on the last and sets up the next, time goes to the work that matters, and students are asked to explain, apply and transfer what they know, not only to recall it or click the right box.
Is it taught in a way the research supports, with honest claims?
We look for a clear teaching model carried through the lessons: worked examples, guided practice that releases to independent work, and real opportunities to retrieve, discuss and apply. Claims about results should be cited or honestly bounded. A program that promises results by matching a child to a learning style is making a claim the research does not support.
Can you actually see what your child learned, not just what they finished?
Completion is not mastery. We look for checks that catch misconceptions, work that a person can inspect, clear criteria for what good looks like, feedback that points to a next step, and records that show progress against real objectives rather than a streak or a percentage bar.
Does a qualified adult read your child's work and respond to it?
This is the question most buying decisions turn on, and it is rarely on the pricing page. A licensed teacher employed by the program counts. A parent whose teaching role is genuinely required, and who is given the guidance to do it, counts. A dashboard nobody is obliged to open does not, and neither does automatic scoring on its own.
How much work is this for you, and does it help you do that work?
Whoever teaches at home deserves an honest answer about the load. We reward programs that publish real prep and teaching time, and that supply the scheduling, answer keys, rubrics and adult-level explanations needed to actually run the material.
Does it flex for a struggling learner, an advanced one, or a different kind of learner?
Real flexibility keeps the learning intact: scaffolds that support without removing the thinking, more than one way into a task, genuine depth for a student who is ready, and support for readers and language learners who need it.
What does it truly cost, in money and time, and will it work where you live?
The whole cost, including renewals, consumables and what has to be re-bought for the next child. Then the practical questions that matter here: bandwidth, whether anything works offline, and what it costs to ship a box of books to a community off the road system.
Is this preparing a student for college, or just for a diploma?
The dimension a teacher asked us to add. We look for validated advanced pathways with prerequisites that are actually enforced, a real schedule with consequences, checkpoints that cannot be bypassed, and work a person has to evaluate. A program a student can finish in weeks with nobody reading anything may hand over a credit, but it has not built a scholar.
Reviewers work on a detailed five-point scale for each dimension, weighted by how much that dimension matters for the way the curriculum is being used. Those weights differ between a primary program, which has to carry a child's education, and a supplement, which only has to do one job well. The result is converted to the familiar five-star rating.
Where a rating has been limited by one of the guardrails below, we show that, and why.
An average can hide a hole. These rules sit over the whole rubric so that a serious gap stays visible no matter how well a curriculum scores elsewhere.
If we cannot inspect enough real student, adult and assessment material, the curriculum is marked unrated rather than guessed at. Missing evidence never becomes a star score.
When a curriculum is weak on content, assessment, accountability or academic demand, it carries a visible warning that it should not carry a child's whole education without a documented plan alongside it.
Raised when a full year of work can be finished quickly with nobody checking. It is not raised when a teacher or a genuinely required parent is in the loop, because an adult teaching daily is not the same as a child racing through alone.
A mostly-online curriculum where no qualified adult reads the student's work cannot be rated above 2.5 stars as a primary program, whatever else it does well. The cap does not apply to supplemental use, and it lifts as soon as a real adult loop exists.
We did not invent a standard from scratch. We studied the systems educators and homeschool families already trust, took what each does well, and added what none of them do: serving the parent and the teacher with the same rubric, and asking directly whether a real adult is in the loop.
The independent nonprofit whose educator-led reviews districts use to judge K-12 materials. Its sequential gateways for focus, coherence, rigor and usability shape how we weigh content quality.
The long-standing homeschool review standard, and the origin of our attention to parent workload, ease of use and how load-bearing the teacher's manual is.
The Instructional Materials Evaluation Tool from Student Achievement Partners, which informs how we treat alignment, evidence and access for all learners.
The classical education standard for cumulative sequence and staged academic demand, and a reminder that rigor is not the same as volume.
The rubric was developed with and is validated by a certified teacher. Reviews are done against published evidence, and where a vendor keeps something behind a login we say so rather than assume. We take no payment from any publisher, and no curriculum can buy a rating or a placement. When we get something wrong, tell us and we will re-review it.
Every curriculum we have reviewed shows its rating, its score on all nine dimensions, and any flags it carries.
