Oregon Homeschool Standardized Testing: Approved Tests and What You Need to Know

Most Oregon homeschool families assume standardized testing is an annual ordeal. It isn't. Oregon requires testing at the end of just four grade years — 3, 5, 8, and 10 — and only three test options are approved by the State Board of Education. If you're running a microschool or learning pod, coordinating this across multiple families is manageable once you understand the structure. Here's everything you need to know.

When Testing Is Required

Oregon mandates standardized testing at the completion of grades 3, 5, 8, and 10 only. Students in grades 1, 2, 4, 6, 7, 9, 11, and 12 are not required to test under the home education statute.

All testing must be completed by August 15 of the applicable grade year. Plan testing in the spring or early summer to avoid deadline pressure. Waiting until August to schedule a neutral tester typically creates logistics problems, especially in high-demand testing seasons when qualified testers book up.

One important exception: homeschooled students who participate in public school interscholastic activities (most commonly sports under the Tim Tebow law) are required to demonstrate satisfactory progress annually, not just at the four grade checkpoints. If your pod students are accessing public school sports programs, they need annual testing — plan accordingly.

New families withdrawing from public school get an 18-month grace period before their first required test. This means withdrawing in September doesn't trigger a March test — the first required assessment won't be due until well into the following school year.

The Three Approved Tests

The Oregon State Board of Education approves a specific list of comprehensive assessments. As of current ODE guidance, three tests satisfy the requirement:

Iowa Tests of Basic Skills (ITBS)

The ITBS is the most widely used choice among Oregon homeschool families. It measures reading comprehension, language arts, mathematics, science, and social studies. Scores are reported in grade equivalents and national percentile ranks. The national percentile rank is what Oregon uses to determine compliance with the 15th percentile threshold.

The ITBS is published by Riverside Insights and is available through several homeschool testing services that will administer it on-site or at your pod location. It's particularly well-suited for microschool group testing because the same administration can cover multiple grade levels simultaneously.

Stanford Achievement Test Battery (SAT-10)

The Stanford Achievement Test — completely distinct from the college admissions SAT — is a comprehensive norm-referenced battery covering reading, mathematics, language, science, and social science. It is widely recognized and accepted by all Oregon ESDs. Many families prefer the Stanford because of its reputation for academic rigor and its detailed diagnostic subscores.

Terra Nova / CAT 3 (California Achievement Test)

The Terra Nova is the least commonly used of the three approved options in Oregon but is fully accepted. It covers reading, language arts, mathematics, science, and social studies. Some testing services offer the Terra Nova at lower cost than the ITBS or Stanford.

What doesn't count: Oregon does not accept state assessments from online charter school programs, portfolio evaluations, narrative assessments, or unofficial skills tests. If a family is tempted to use an unapproved test because it's cheaper or more convenient, it will not satisfy the ODE requirement.

Who Can Administer the Test

Oregon requires a qualified, neutral tester — someone other than the parent who has been providing the child's instruction. The law requires both neutrality (not the instructing parent) and qualification (professional background in education or assessment).

Accepted neutral testers include:

• State-certified or licensed teachers (active or retired)
• School administrators
• Educational psychologists or licensed evaluators
• Homeschool testing organizations that provide qualified administrators

Some Oregon ESDs maintain informal lists of local neutral testers. Testing organizations that specialize in homeschool assessment will typically come to your location for a group session, which is the most efficient approach for a pod.

The 15th Percentile Standard

Oregon's performance threshold is a composite score at or above the 15th national percentile. This is not a per-subject requirement — the composite across all tested areas must reach the 15th percentile.

A few things to understand about this threshold:

The 15th percentile is relatively accessible. A student scoring at the 15th percentile has performed better than 15% of the national norming population. For a student receiving consistent, attentive instruction in a small-group pod setting, scoring at or above this level is not typically difficult.

If a student scores below the 15th percentile composite:

1. The parent may continue homeschooling but must schedule a second test before the end of the following school year.
2. If the second test score declines rather than improves, a third test is required within one year.
3. After the third test, the ESD superintendent may intervene: options include continuing home instruction, mandating supervision by a licensed teacher at the parent's expense, or requiring the student to return to public school for up to 12 consecutive months.

In a pod setting, legal liability for test scores rests entirely with the individual family — not the facilitator and not the pod organizer. However, a student in a well-structured microschool who is falling significantly below grade-level expectations will create operational friction regardless of where legal responsibility sits. Addressing this in your parent agreement upfront — what happens if a family's child is not meeting academic benchmarks — is better than navigating it mid-year.

Group Testing Logistics for Microschools

For a pod with multiple students in testing grades, coordinating individual testing arrangements for each family is inefficient. The most practical approach is to organize a single group testing session.

How it works: The pod organizer contracts a qualified neutral tester to administer the approved test to all age-eligible students simultaneously at the pod location on a set date. Parents register their individual children with the tester in advance, pay their individual testing fees, and the tester handles administration and score reporting.

Logistics to sort out:

• Scheduling: Book the tester 6–8 weeks in advance, particularly in spring. Demand for neutral testers peaks in April and May.
• Which test: The whole group should use the same test for administrative efficiency, but this is not legally required. If families have strong preferences, they can arrange individual testing.
• Cost: Group sessions often reduce the per-student cost. Typical fees range from $50–$150 per student depending on the tester and test format. Build this into your annual pod budget so testing-year families aren't surprised.
• Multi-grade administration: A qualified tester administering the ITBS or Stanford can typically manage multiple grade levels in a single session, since the tests are designed for self-paced, proctored administration.

Score reporting: Each family receives their child's individual score report. Scores are then submitted to the relevant ESD — each family is responsible for their own submission.

Managing Testing Across Pod Years

Running a pod across multiple years means you'll have testing years for some students and non-testing years for others. A simple tracking system prevents anything from falling through.

A spreadsheet with each student's name, current grade, and next required testing year takes five minutes to create and saves significant stress. Update it each September. Flag any student entering grades 3, 5, 8, or 10 that year as requiring testing by August 15.

For the pod parent agreement, include a testing clause that covers: (1) the obligation to test is each family's individual legal responsibility; (2) the pod will coordinate group testing logistics where practical; (3) testing costs are each family's responsibility; and (4) the pod facilitator's academic liability does not extend to individual test outcomes.

The Oregon Micro-School & Pod Kit includes a testing calendar template, neutral tester coordination guide, and the full compliance framework for managing testing across multiple families in a pod setting. Having this organized before your first testing year — especially for pods with grade 3 or grade 5 students — removes a major source of annual stress.

Quick Reference

Approved tests: Iowa Tests of Basic Skills, Stanford Achievement Test Battery, Terra Nova/CAT 3. Must be administered by a qualified neutral tester. Composite score must reach or exceed the 15th national percentile. Newly withdrawn families have an 18-month grace period before first test is due.
