Missouri Learning Standards vs Common Core: What Homeschoolers Need to Know

If you're pulling your child out of a Missouri public school and starting to think about homeschool curriculum, you may have stumbled into the Common Core debate and wondered exactly what Missouri uses — and whether you need to align to it. The short answer: Missouri officially replaced Common Core with its own Missouri Learning Standards back in 2016, and as a homeschooler you are not required to follow either framework. But understanding the history and the practical differences helps you make confident curriculum decisions without chasing a standard that doesn't apply to you.

Did Missouri Ever Adopt Common Core?

Yes. Missouri was one of the early states to adopt the Common Core State Standards Initiative. The state adopted the standards in 2010, joining the majority of U.S. states that signed on to the multistate effort led by the National Governors Association and the Council of Chief State School Officers. Common Core was designed as a shared set of academic benchmarks for English Language Arts and Mathematics, intended to bring consistency across state lines.

Missouri implemented Common Core in its public schools throughout the early 2010s. By the 2013–14 school year, the standards were substantially in place in Missouri classrooms, and the state participated in the Smarter Balanced Assessment Consortium (SBAC) for testing aligned to the new standards.

The political controversy around Common Core that swept the country hit Missouri hard. Legislators, parents, and advocacy groups pushed back against what they characterized as federal overreach into state education policy. The debate wasn't purely partisan — concerns came from conservative groups worried about federal control and from some progressive educators worried about the narrowing of curriculum around standardized tests. The result was a sustained effort to exit the Common Core framework and replace it with state-developed standards.

What Missouri Did Instead: The Missouri Learning Standards

In 2014, Missouri enacted legislation directing the State Board of Education to develop new academic standards independent of Common Core. A review process followed, with public comment periods and revision rounds, and the Missouri Learning Standards (MLS) were adopted in 2016. They were implemented in Missouri public schools beginning with the 2016–17 school year, with full implementation and aligned state assessments — the Missouri Assessment Program, or MAP — in place by 2018.

So the direct answer to "does Missouri use Common Core standards?" is: no, not officially. Missouri uses the Missouri Learning Standards, which are administered by the Missouri Department of Elementary and Secondary Education (DESE).

How Different Are the Missouri Learning Standards from Common Core?

This is where the honest answer is more complicated than the political one. Missouri Learning Standards and Common Core are structurally similar. They cover the same subjects — English Language Arts and Mathematics — with grade-by-grade progressions from kindergarten through high school. They use similar organizational frameworks. Many of the individual benchmarks are nearly identical in substance.

Missouri made deliberate changes in several areas. The Math standards placed some content at different grade levels than Common Core — multiplication of multi-digit numbers, for example, moved earlier in the Missouri sequence. The ELA standards were restructured into different organizational strands and reworded in places. Some content that critics found developmentally inappropriate was shifted or removed.

Educators who have analyzed both sets of standards in detail describe Missouri Learning Standards as a revised and rebranded version of Common Core rather than a wholesale replacement. Some individual standards differ meaningfully. Others are nearly word-for-word the same. The external testing structure changed (SBAC out, MAP in), but the underlying academic expectations align more closely with Common Core than with Missouri's pre-2010 standards.

This doesn't mean the change was cosmetic — Missouri did exercise genuine control over the revision process and made substantive edits in response to public feedback. But if you've seen curriculum marketed as "Common Core aligned" and you're looking at a Missouri public school framework, that curriculum will typically cover the same material, presented in a recognizable sequence.

Do Missouri Homeschoolers Have to Follow the Missouri Learning Standards?

No. Missouri homeschoolers are not required to follow the Missouri Learning Standards or any DESE curriculum framework.

Missouri's homeschool law is set out in Missouri Revised Statutes Section 167.031. Under this statute, a home school is defined as a school conducted by a parent or guardian as the primary instructor. The law specifies what home schools must do:

• Provide at least 1,000 hours of instruction per school year
• Deliver at least 600 of those hours in the five required subjects: reading, language arts, mathematics, social studies, and science
• Deliver at least 400 of those hours at the regular home school location
• Maintain certain records (a written plan of instruction, a daily log, evaluations or samples of the child's work, and a record of subjects taught)

That is the complete list of legal requirements. There is no requirement that instruction align to Missouri Learning Standards. There is no requirement to follow DESE's grade-level progressions, use DESE-approved materials, or prepare your child for MAP testing. Missouri's homeschool law treats your home school as a private educational institution, not as a branch of the public system.

This means the debate over whether Missouri's standards are better or worse than Common Core is largely irrelevant to your decision-making as a homeschooler. You are not subject to either.

Why Parents Ask This Question — and Why It Matters for Withdrawal

Most parents who ask about Missouri Learning Standards versus Common Core are in one of two situations. Either they are preparing to withdraw from public school and want to know what their child was learning and whether they need to continue along the same track — or they are researching curriculum and seeing products marketed as "Common Core aligned" or "MLS aligned" and wondering which standard actually applies in Missouri.

On the first question: when you formally withdraw your child from a Missouri public school, you exit the DESE system entirely. You are no longer operating within the public school's scope-and-sequence, and you don't need to pick up where the MAP testing framework left off. Your child's education is now governed by your plan of instruction, not DESE's grade-level expectations.

On the second question: because Missouri Learning Standards and Common Core are substantially similar in structure, curriculum products marketed as "Common Core aligned" will generally cover the same material as DESE's current framework. If you find a curriculum you love that uses Common Core language, it is not misaligned with what Missouri public schools teach — and it doesn't matter anyway, because you're not required to align to either.

What About Re-Enrollment Later?

Some families homeschool temporarily — for a year or two during a difficult transition, for a specific medical or family situation — and plan to return to public school eventually. If that's your situation, you might wonder whether staying loosely aligned to Missouri Learning Standards helps with re-enrollment.

Missouri school districts place returning students based on their own assessment processes, not solely on what materials you used at home. Your child's placement will depend on what skills they demonstrate when they re-enroll, not on whether your curriculum carried the MLS label. Using a rigorous curriculum that covers the core subjects well — whether it's Common Core aligned, classical, Charlotte Mason, or anything else — prepares your child more effectively than trying to track the exact progression in a DESE framework you're not required to follow.

Getting the Withdrawal Process Right

If you haven't formally withdrawn your child from their Missouri public school yet, that's the first practical step before any curriculum decision. Missouri has a specific process for notifying the district of your intent to homeschool, and getting the paperwork right matters — both for your family's legal standing and to ensure your child's attendance records are correctly updated.

Our guide to Missouri homeschool withdrawal walks through the withdrawal process step by step: the notice requirements under Section 167.031, how to communicate with your district, what records to start keeping from day one, and how to set up your written plan of instruction so it meets the statutory standard without being unnecessarily complicated. If you're just starting out, this is the right foundation before diving into curriculum research.

The Common Core debate is real, and Missouri's decision to develop its own standards reflects genuine differences of opinion about who should control academic expectations for children. But for homeschoolers, it's largely a background fact rather than an operational concern. Your job is to meet Missouri's homeschool statute — and that law gives you substantial freedom to educate your child the way you see fit.
