Minnesota Homeschool Approved Tests: Iowa, Stanford, NWEA MAP and More

Minnesota law requires annual standardized testing for homeschooled children ages 7 through 17 — but it doesn't specify a single approved test. The statute says the parent and the resident school district superintendent must mutually agree on which nationally norm-referenced test to use, how it will be administered, and where.

In practice, several tests are widely accepted across Minnesota districts. Knowing which ones qualify, what each tests, and who can administer them helps you choose the right option for your family or micro-school rather than defaulting to whatever the district suggests.

The Legal Requirement

Under Minn. Stat. §120A.22, the test must be:

• Nationally norm-referenced — meaning your child's scores are compared to a national sample of same-age students, expressed as a percentile ranking
• A standardized achievement test — comprehensive coverage of core academic subjects, not a single-subject assessment
• Mutually agreed upon by parent and superintendent before administration

The law does not require you to use a district-administered test or to test at a district facility. You can administer the test privately at home or at your micro-school, provided the proctor meets the test publisher's requirements (typically a bachelor's degree).

Tests Widely Accepted in Minnesota

Iowa Assessments (ITBS / Iowa Form E)

The Iowa Assessments — previously called the Iowa Tests of Basic Skills — are the most commonly used homeschool standardized test in Minnesota. They cover reading, language arts, mathematics, science, and social studies and are published by Riverside Insights.

Iowa Assessments produce a full battery score expressed as a national percentile rank, which is exactly what Minnesota's 30th percentile threshold applies to. They are available in paper-and-pencil format through testing service providers and can be privately administered by someone with a bachelor's degree.

Homeschool testing services that sell Iowa Assessments to individual families typically charge between $30 and $60 per student depending on the grade level and the specific form ordered.

Stanford Achievement Test Series (SAT-10 / Stanford 10)

The Stanford Achievement Test from Pearson covers grades K-12 in reading, mathematics, science, and social studies. It has a long track record with homeschool families and is well-documented enough that virtually every Minnesota district will accept it.

The Stanford 10 is available through several homeschool testing vendors who also provide scoring and percentile reports. Like the Iowa Assessments, it requires a proctor who meets the publisher's qualifications — typically a bachelor's degree.

NWEA MAP Growth

NWEA MAP Growth is a computer-adaptive test that adjusts question difficulty based on a student's responses, providing a more precise measurement of where a child is actually performing relative to grade-level expectations. MAP tests are widely used in Minnesota public schools, which means many superintendents are already familiar with the reporting format.

MAP Growth produces a RIT score and a percentile ranking against national norms, satisfying the norm-referenced requirement. Access to MAP Growth is typically through a school or testing center — it's less commonly available for direct purchase by individual homeschool families compared to Iowa or Stanford tests. Some homeschool co-ops and micro-schools establish accounts with NWEA directly to administer MAP for their students collectively.

Peabody Individual Achievement Test (PIAT)

The Peabody Individual Achievement Test is an individually administered assessment, meaning a qualified examiner tests one child at a time rather than administering a group test. It covers reading recognition, reading comprehension, mathematics, spelling, and general information.

The PIAT is often used for students with anxiety around timed group testing, or for students with learning differences who perform better in a one-on-one format. Because it requires individual administration by a trained examiner (typically a psychologist or educational specialist), it's more expensive — but it produces valid norm-referenced percentile scores that satisfy Minnesota law.

California Achievement Test (CAT) and Woodcock-Johnson

The CAT and the Woodcock-Johnson Test of Achievement are both accepted by Minnesota districts and are commonly used by homeschool families nationally. The CAT is available through homeschool testing vendors. The Woodcock-Johnson is individually administered, similar to the Peabody, and is often used in special education evaluations — making it a natural fit if a family is already pursuing an evaluation under the 30th percentile requirement.

How to Agree on a Test With Your Superintendent

Minnesota law requires mutual agreement between parent and superintendent. In most districts, this is a formality rather than a negotiation. When you file your annual Compulsory Instruction Report, you can include a note indicating which test your child will take and your planned administration timeline.

Most superintendents will accept any of the nationally recognized tests listed above without requiring justification. If a superintendent insists on a specific test or on district-administered testing, they are overstepping the statute — the law says mutual agreement, not superintendent-mandated test.

If you encounter resistance, put your communication in writing and reference Minn. Stat. §120A.22. Districts that push for exclusive use of the MCA (Minnesota Comprehensive Assessment) are asking for something beyond what the homeschool law requires; MCAs are a public school assessment, not a homeschool testing option.

Choosing the Right Test for Your Situation

For straightforward annual compliance with minimal cost: Iowa Assessments or the California Achievement Test, administered at home or at your micro-school by a proctor with a bachelor's degree.

For students familiar with district testing formats: NWEA MAP Growth, especially if your superintendent is already familiar with MAP data and you can arrange access through a cooperative arrangement or testing center.

For students with testing anxiety or learning differences: Peabody or Woodcock-Johnson, administered by a qualified specialist in a low-pressure one-on-one setting.

For multi-family pods looking to test everyone efficiently: Group administration of the Iowa Assessments or Stanford 10 at your pod site, with your facilitator serving as proctor (assuming they hold a bachelor's degree).

What Happens to the Scores

Test results do not go to the district. You keep them on file for a minimum of three years. If any student scores at or below the 30th percentile on the total battery, Minnesota law requires an independent educational evaluation — but the results of that evaluation also remain private.

The Minnesota Micro-School & Pod Kit includes a testing compliance checklist that covers how to document your superintendent agreement, administer group testing at a pod site, and handle below-threshold scores — including the evaluation referral process — without unnecessary district involvement.

Testing is annual and non-negotiable under Minnesota law. Choosing the right test upfront removes most of the friction.
