Homeschool Standardized Testing at Home: Your Options and What to Expect

At some point, most homeschooling families have to navigate standardized testing — whether their state mandates it, they want to benchmark their child's progress, or they're preparing for college admissions. The options are more varied than most people realize, and the costs range from completely free to several hundred dollars depending on the test and how it's administered.

Here's a practical breakdown of what's actually available, what each option costs, and how testing fits into your annual homeschool documentation.

Who Actually Has to Test

Roughly 13 states require some form of standardized testing for homeschooled students. The grade levels and specific requirements vary significantly by state.

Hawaii requires nationally normed standardized test scores for students in grades 3, 5, 8, and 10. In those years, submitting official test scores automatically satisfies the annual progress report requirement — you don't need a separate written evaluation. In non-mandatory years, most Hawaii families choose the parent-written evaluation method instead of testing voluntarily.

States like Texas, California, and Oregon have no testing mandate at all. Others, like North Carolina and Washington, require annual testing.

If your state doesn't mandate testing, you may still choose to test for your own information — to identify gaps, reassure yourself that learning is on track, or build documentation for future college applications.

Tests That Can Be Administered at Home

Several widely accepted assessments can be administered at home by the parent.

Iowa Assessments (ITBS): One of the most commonly used norm-referenced tests for homeschoolers. Measures reading, language arts, mathematics, science, and social studies. Accepted in most states that allow parent-submitted test scores, including Hawaii. Can be purchased through authorized homeschool testing services; parent-proctored versions are available.

Stanford 10 (SAT-10): Frequently used by Hawaii homeschoolers because it's specifically named in HIDOE guidance as an acceptable nationally normed assessment. Provides stanine scores (important for Hawaii's "upper two-thirds" adequacy standard). Available through testing services with parent-proctored versions.

California Achievement Test (CAT): An older norm-referenced assessment available through several homeschool testing companies at moderate cost. Parent-administered and widely accepted.

NWEA MAP Growth: Computer-adaptive assessment that adjusts difficulty based on student responses. Used by many schools and can be arranged through testing providers who serve homeschool families. Results include scale scores and grade equivalent data useful for longitudinal tracking.

For all of these, you'll purchase from an authorized testing provider rather than directly from the publisher. Prices typically run $25–$60 per test, depending on the provider and whether you want scored reports.

Free and Low-Cost Testing Options

Public school testing: In Hawaii, parents can request that their child participate in the Smarter Balanced Assessment or the Hawaii State Assessment (HSA) alongside public school students — free of charge. This satisfies the mandatory testing requirement for grades 3, 5, 8, and 10 without any cost to the family. Contact the principal of your geographically assigned public school to arrange this. The practical limitation is scheduling: you'll need to coordinate with the school's testing calendar.

Khan Academy assessments: Not normed assessments in the formal sense, but Khan Academy's diagnostic and unit assessments are free and give useful feedback on mastery. These work well for internal tracking and curriculum planning, but they don't generate the kind of official score reports that satisfy state reporting requirements.

Renaissance Learning Star Assessments: Some homeschool co-ops and learning pods have institutional subscriptions that allow member families to use Star Reading and Star Math at low or no cost. Results include grade equivalent scores and instructional recommendations.

CAT e.g., through Seton Testing Services: Seton offers parent-administered testing starting around $30, making it one of the more affordable options for official score reports.

How to Read Your Test Results

When your state uses test scores for compliance purposes, it's important to understand what the results actually mean.

Percentile rank: Compares your child's score to a nationally normed sample. A 70th percentile score means the child scored higher than 70% of the norm group.

Stanine: A 1–9 scale derived from percentile scores. Stanines 1–3 are below average, 4–6 are average, and 7–9 are above average. Hawaii's law specifically requires scores in the "upper two-thirds of the stanines" to demonstrate adequate progress — this means stanines 4 through 9.

Grade equivalent: Describes performance in terms of a grade level (e.g., 5.3 means fifth grade, third month). Useful for curriculum planning but not the primary metric for compliance purposes.

Scale score: A raw numerical score on a continuous scale, most useful for measuring growth over time across years on the same test (particularly with MAP Growth).

For Hawaii families, the stanine is the number that matters most for principal review. If your child's stanine score falls in the upper two-thirds (stanine 4 or above), you've demonstrated adequate progress by testing.

Fitting Testing Into Your Annual Documentation

If you're in a mandatory testing year (grades 3, 5, 8, or 10 in Hawaii), the test report essentially does all the work for your annual progress report. Attach the official score report to your annual report submission and you're done for that year.

In non-mandatory years, if you choose to test voluntarily, the results make excellent supporting documentation even when you're submitting a parent-written evaluation. Test scores add an objective data point that complements your narrative evaluation.

For families building year-over-year records — especially heading into high school — keeping a testing log with results from each year creates a longitudinal record that's valuable for both state compliance and college admissions. Universities like the University of Hawaii encourage homeschool applicants to submit SAT or ACT scores alongside their parent-issued transcripts.

The Hawaii Portfolio & Assessment Templates include a testing log and guidance on integrating official test scores into your annual progress report — whether you're in a mandatory testing year or choosing to test voluntarily.
