7 Homeschool Testing Options Compared: Which One Actually Helps You Teach Best?
There is no shortage of standardized tests available to homeschool families. The problem is that most of them were never designed for you.
The Iowa, the Stanford 10, the CAT, MAP Growth, the CLT, TerraNova. They all have long track records, impressive-sounding names, and endorsements from organizations that have been in education for decades. But when you sit down and look at what each one actually delivers to a homeschool parent trying to figure out what to teach next Tuesday, the options start to look thinner than the brochures suggest.
Here is an honest look at the major tests, what they cost, what they actually tell you, and where they fall short for families like yours.
A Quick Word About Why These Tests Exist
Most of the tests on this list were built for public and private school systems. They were designed to generate end-of-year benchmark data for administrators, counselors, and school boards managing hundreds or thousands of students. The reports they produce reflect that. Percentile rankings, stanines, grade equivalents. These are metrics that matter when you are comparing schools and tracking district performance across populations. They are not metrics that help a parent sitting at the kitchen table figure out whether their child actually understands fractions.
That does not mean the tests are useless. It means they were built to answer a different question than the one you are asking.
You are asking: where is my child strong, where are they weak, and what do I need to adjust? That requires topic-level detail, not just a broad subject score.
The Major Tests at a Glance
Iowa Assessments (ITBS/ITED)
The Iowa is often considered the gold standard of homeschool standardized tests. It is a thorough, well-constructed assessment covering reading, language, math, science, social studies, and more. It has been around since the 1930s and is available to homeschool families through providers like BJU Press and Seton Testing.
Cost: Roughly $50 to $85 per student depending on format (online or paper) and provider. Per student, per test, one time.
What you get: Percentile rankings, stanines, and grade equivalents broken out by broad subject area. Some providers offer additional sub-score breakdowns, but the level of detail varies.
The catch: Most providers require the test to be administered by someone with a bachelor’s degree. Results take 5 to 7 business days for online versions, longer for paper. There are restrictions on retesting within 3 months. And you are paying per student every time. For a family of four kids, a single round of Iowa testing can easily run $200 to $340.
Stanford 10 (SAT-10)
The Stanford Achievement Test, 10th Edition, is widely regarded as one of the most rigorous standardized tests available. It is offered online through BJU Press and through Seton Testing, among others.
Cost: Roughly $55 to $90 per student depending on provider and format.
What you get: Detailed percentile and stanine scores across reading, math, language, spelling, science, social studies, and listening. The Stanford 10 provides more sub-score detail than most competitors.
The catch: It is long. The math section in particular is known for running well past the suggested time limits, which can be stressful for younger students or kids who have not done a lot of formal timed testing. Results take 5 to 7 business days minimum. Like the Iowa, it is per-student pricing with no family rate. And administrator requirements vary by provider.
CAT (California Achievement Test)
The CAT is the budget pick. It is the cheapest standardized test widely available to homeschool families and one of the easiest to administer because no special credentials are required. Available through Academic Excellence and Christian Liberty Press.
Cost: About $25 to $40 per student depending on version and provider.
What you get: Grade equivalents, percentiles, and stanines for reading, language arts, math, and spelling.
The catch: The most commonly sold version is normed against student data from 1970. Even the CAT/5 uses 1992 norms. Old norms inflate scores, which means your child may look like they are performing better than they actually are relative to students today. The base version does not include science or social studies. And the results are broad subject scores with no topic-level breakdown.
MAP Growth (NWEA)
MAP Growth is the most modern test on this list. It is adaptive, meaning the questions adjust in difficulty based on how your child answers. It is used in roughly 1 in 5 U.S. public schools and is available to homeschool families through Homeschool Boss.
Cost: Pricing is per student, per subject, per testing window. A full assessment for one child across multiple subjects can run $50 to $75+, and you need to schedule during specific testing windows.
What you get: Adaptive scoring with RIT scores, detailed reports (30 to 60 pages per subject), growth norms, and alignment to learning standards.
The catch: MAP was built for school districts. The reports are comprehensive to the point of being overwhelming for a parent who just wants to know what to focus on. You are paying institutional-grade prices for institutional-grade data. Most homeschool families do not need 60 pages of psychometric analysis. They need a clear answer: where is my child strong and where do they need help?
CLT (Classic Learning Test)
The CLT is the newcomer, built specifically as an alternative to the SAT and ACT. It has gained significant traction in the homeschool community, particularly among classical and Christian education families. The CLT suite covers grades 3 through 12 with exams that assess reading, grammar, writing, and math.
Cost: Varies by exam level. The CLT3-8 exams are approximately $29 to $39 per student.
What you get: Norm-referenced scores that satisfy testing requirements in most states. The CLT is well-designed, parent-proctored, and respected by over 300 partner colleges.
The catch: The CLT is primarily a college-readiness and compliance tool. It is excellent at what it does, but it does not provide the kind of topic-level diagnostic breakdown that helps you adjust day-to-day teaching. If you want to know whether your child understands fractions specifically, or where they stand in life science versus earth science, the CLT is not built for that level of detail.
TerraNova (CAT/6)
The TerraNova is essentially the updated successor to the CAT. It uses more current norms (2005-2011) and includes science and social studies in the standard battery. Available through Seton Testing and Family Learning Organization.
Cost: About $35 to $45 per student.
What you get: Percentile rankings and grade equivalents across a broader range of subjects than the older CAT versions.
The catch: Better than the 1970 CAT, but still a single-snapshot, per-student, broad-subject assessment. No parent dashboard, no attempt history, no topic-level scoring. You get a score report and that is the end of the relationship.
The Pattern You Should Notice
Every test on this list shares the same basic limitations:
Per-student pricing. Every child costs more. Every test attempt costs more. Larger families get punished financially for doing the right thing.
Broad subject scores. You find out your child is “above average in math.” You do not find out they are strong in geometry but struggling with fractions. The gap that actually matters stays invisible.
One-and-done snapshots. You get a result. There is no easy way to test again, compare results over time, or see whether a weak area is getting better or worse without buying another test and doing the comparison manually.
No parent dashboard. You get a PDF or a printed report. No portal, no ongoing access, no ability to compare siblings or track trends.
These are not bad tests. They are tests built for a system you chose to leave. They were designed to give institutions broad performance data, not to give a parent actionable insight into what their child specifically needs to learn next.
What Homeschool Test Track Does Differently
Homeschool Test Track was built by homeschool parents who got tired of paying for tests that did not answer the questions that actually mattered. Here is what we built instead:
Topic-level scoring. When your child takes a math assessment, you see how they performed in algebra, geometry, measurement, and data analysis separately, each compared to the national average for that specific topic. You are not squinting at a single percentile trying to guess what it means. You are looking at a clear breakdown that tells you exactly what to focus on.
Strengths and Learning Gaps, sorted automatically. Your parent dashboard takes every tested topic and puts it in one of two columns: areas where your child is beating the benchmark, and areas where they are falling behind. Each entry shows the exact score and the distance from the national average. You open it and you know what to work on.
$145 for up to 6 kids, all year. One price. One family. All four core subjects (Math, Science, Language Arts, Social Studies). Grades 1 through 6. Unlimited test attempts. No per-student fees, no per-test charges, no seasonal testing windows. For a family of four children, that is roughly $36 per child per year for comprehensive, repeatable assessment with instant results.
Unlimited retakes with full attempt history. Test in September. Adjust your curriculum. Test again in January. Every attempt is saved. You can see whether gaps are closing, holding, or widening over time. That is how you actually measure whether your teaching is working.
Instant results. Your child finishes the test and the scores are in your dashboard immediately. No waiting days, no mailing booklets, no separate scoring fees.
No automatic renewal. You choose when to renew. Your money, your decision.
The Bottom Line
If you need a compliance score for your state and nothing more, most of the tests above will get you there. But if you are testing because you want to do right by your kids and make sure your teaching is hitting the mark, you need more than a percentile and a pat on the back.
You need specific, topic-level data that tells you where each child stands, benchmarked against something meaningful, with the ability to track progress over time and test as often as you need without paying more every time. That is what Homeschool Test Track was built to do.
