Homeschool Testing Guide: Annual Assessments, Portfolios, and Standardized Tests

The word "testing" can produce a knot in the stomach — for kids and parents alike. But in the homeschool context, assessment doesn't have to be a stressful event. It's simply the process of understanding where your child is academically and, in states that require annual evaluation, demonstrating that learning is happening.

This guide will walk you through everything you need to know: which states require testing, what your options are, how different types of assessments work, where to take tests, and how to interpret results in a way that actually helps your homeschool.

First: Does Your State Require Testing?

Not every state requires annual academic assessment for homeschooled students. Requirements fall into a few general categories:

States that require annual standardized testing — A defined list of approved tests must be administered, and in some states, results must be submitted to a local official.

States that allow testing OR portfolio review — Families can choose between standardized testing and submitting a portfolio of work (often reviewed by a certified teacher or evaluator).

States that allow multiple options — The broadest category; families might choose testing, portfolio, certified teacher evaluation, or other methods depending on what the state allows.

States with no assessment requirement — Some states require simply filing notice that you are homeschooling, with no ongoing evaluation required.

Because requirements vary so much and change over time, we strongly recommend checking the specific page for your state on curiosityharbor.org, where we maintain current information on testing requirements, approved tests, and submission procedures.

Types of Approved Assessments

Standardized Achievement Tests

Standardized tests are the most familiar form of academic assessment. They compare your child's performance to a national normed sample — meaning the score reflects where your child stands relative to other students at the same grade level who took the same test.

For homeschoolers, standardized tests are typically administered at home (by a parent or qualified administrator) or through a testing center. They're untimed or have generous time limits for younger students, and they're taken individually rather than in a group setting.

The most commonly approved and widely used tests include:

Iowa Assessments (Iowa Test of Basic Skills / Iowa Test of Educational Development) One of the most widely accepted tests for homeschoolers. The Iowa assessments cover reading, language arts, mathematics, science, and social studies. They have been used for decades and are well-regarded for reliability. Available through several testing services and some homeschool co-ops.

Stanford Achievement Test (SAT-10 or Stanford 10) Not to be confused with the college admissions SAT, this is a separate K-12 achievement test published by Pearson. It's widely accepted in states that require standardized testing and is available through testing services that work specifically with homeschoolers.

California Achievement Test (CAT/CAT5/CAT6) Another long-established achievement test, accepted in most states that require standardized assessment. The CAT5 version is particularly common among homeschoolers. Some versions can be administered by a parent without special qualifications.

Woodcock-Johnson Tests of Achievement A more detailed diagnostic assessment, often used when families want to understand specific strengths and weaknesses in depth. Typically administered by a professional, so it's less common as a routine annual assessment but valuable for understanding a child's learning profile.

Terra Nova Accepted in many states, the Terra Nova covers core academic subjects and is available in complete battery or shorter survey versions.

Test	Grade Range	Admin	Parent-Friendly	Cost Range
Iowa Assessments	K–12	At home or testing center	Yes	$30–$70
Stanford 10	K–12	At home or testing center	Yes	$25–$60
CAT5	K–12	At home	Yes	$25–$55
Terra Nova	K–12	At home or testing center	Yes	$30–$65
Woodcock-Johnson	Pre-K–adult	Professional required	No	$200–$400+

Prices are approximate and vary by provider and battery length.

Portfolio Assessment

A portfolio is a curated collection of your child's work over the course of the school year, assembled to demonstrate academic progress. In states that allow portfolio review, this can be an excellent alternative to standardized testing — particularly for students who are creative learners, have test anxiety, or whose learning doesn't map neatly to grade-level expectations.

A typical homeschool portfolio might include:

• Samples of writing at multiple points during the year (showing growth)
• Math worksheets, problem sets, or project documentation
• Reading logs, book reports, or narration records
• Science lab reports, nature journals, or project documentation
• A log of books read aloud
• Photos or descriptions of projects, field trips, or hands-on activities
• Test scores from curriculum unit tests
• A parent-written narrative describing the year's studies

In states that require portfolio review, the portfolio is typically reviewed by a certified teacher who confirms that the student is making appropriate academic progress. The teacher doesn't grade the work — they're looking for evidence that learning is occurring.

Certified Teacher Evaluation

Some states allow a certified teacher (public or private) to meet with the student, review their work, and provide a written statement that the child is receiving an adequate education. This is similar to portfolio review but more interview-based. It can be a good option for families who have a relationship with a local teacher who understands home education.

Other Evaluation Options

A handful of states accept other forms of evaluation, such as:

• Evaluation by a licensed psychologist
• Completion of an approved correspondence or umbrella school program
• Subject-area testing through programs like the AP Exams or CLEP

How to Prepare for Standardized Testing

Standardized tests for homeschoolers are not high-stakes in the way that school accountability tests often are. They're meant to give you useful information, not to evaluate your qualifications as a teacher. Here's how to approach preparation without unnecessary stress.

Keep expectations proportionate. Homeschooled students typically perform at or above grade level on standardized tests, and many score well above. But scores below the 50th percentile aren't a crisis — they're information. They may simply reflect areas where your curriculum covers topics in a different order, or where your child genuinely needs more time.

Familiarize your child with the format. For many kids, the most intimidating part of any test is unfamiliarity. Walk through a few practice questions together. Talk about what to do when you don't know an answer (make your best guess and move on). This isn't "teaching to the test" — it's reducing anxiety.

Schedule thoughtfully. Choose a time of day when your child is fresh, not when they're tired or hungry. Some families test in the morning over several days, taking one section per day rather than cramming everything into a single long session.

Don't over-prepare. Unless your state's law makes test scores consequential, excessive test prep is probably not the best use of your instructional time. A well-rounded year of learning is better preparation for these tests than drilling practice questions.

Discuss the purpose. Kids do better when they understand why they're doing something. "This test helps us see how you're doing in reading and math compared to other kids" is honest and straightforward. Framing tests as an interesting challenge rather than a judgment tends to produce calmer test-takers.

Where to Take Tests

You have several options for where your child takes standardized tests:

At home. Many tests approved for homeschoolers can be administered by a parent. You'll follow a detailed instruction manual and administer the test in a quiet, distraction-free environment. Results are submitted to the scoring service, which sends back a score report.

Testing services. Several national services specialize in homeschool testing. Seton Testing Services, BJU Press, and Hewitt Homeschooling are examples. These services mail materials, you administer the test, and you mail it back. They often handle all the logistics and provide clear instructions.

Homeschool co-ops. Many co-ops organize group testing days where a qualified administrator oversees testing for multiple families. This can make the experience feel more official and take the logistical burden off individual parents.

Libraries and community centers. Some public libraries work with testing services to offer homeschool testing days.

Community colleges and testing centers. For older students taking advanced assessments (PSAT, SAT, ACT, CLEP, AP), community college testing centers are often accessible.

Understanding Score Reports

When you receive your child's score report, you'll see several types of scores. Here's what they mean:

National Percentile Rank (NPR or NCE): The percentage of students in the norming group who scored at or below your child's score. A score at the 70th percentile means your child scored higher than 70% of the normed sample. This is the most commonly cited score.

Grade Equivalent (GE): Expressed as a grade and month (e.g., 5.3 = fifth grade, third month). This is often misunderstood. A GE of 7.0 for a fourth grader doesn't mean the child should be placed in seventh grade — it means they got the same score that the average seventh grader got. Use this score as one data point, not a placement decision.

Standard Score: A number that allows comparison across subtests and over time. Less intuitive but useful for tracking longitudinal progress.

Stanine: A 1-9 scale where 4-6 is average, 7-9 is above average, and 1-3 is below average. Rough but quick to interpret.

The most useful thing you can do with scores is compare them to your child's own results over time — that's where you'll see real information about growth and areas that may need attention.

Testing for College Admissions

For high school homeschoolers planning to attend college, testing takes on additional importance. Most colleges accept homeschoolers, and standardized test scores (SAT, ACT) are typically part of the admissions process — in fact, strong test scores can help establish academic credibility for students without traditional transcripts.

Other useful assessments for high school students include:

PSAT/NMSQT — Available through some schools to outside test-takers; qualifies students for National Merit Scholarship consideration.

AP Exams — Subject-matter exams that can earn college credit. Homeschoolers can take AP exams by contacting a local school that offers them and asking to be included as an outside test-taker.

CLEP Exams — College-Level Examination Program tests allow students to demonstrate college-level knowledge and earn college credit at many institutions. Widely available at community colleges.

Dual Enrollment — While not technically a test, completing community college courses as a high schooler produces college transcripts that can be very useful in the admissions process.

Making Testing Work for Your Homeschool

The most important shift is to approach assessment as something that works for you, not something you're being checked up on. Tests can genuinely tell you useful things:

• Your child is strong in reading comprehension but struggles with reading speed — that suggests a different kind of support than struggling with comprehension itself.
• Math computation scores are high but math problem-solving scores are lower — maybe more time on word problems and applied math is warranted.
• Scores are consistent and solid across the board — great, carry on.

None of this requires expensive preparation or produces stress when approached matter-of-factly. Treat the annual assessment as one useful data point in a year full of rich learning, and it will serve its purpose without taking over your spring.
