The 12-member high school mathematics standards review and revision committee completed recommended revisions in two phases. In the first phase, they worked from April 2025 through November 2025 to make revisions to the high school mathematics standards. These revisions incorporated public feedback collected prior to the revision that expressed a desire for high school mathematics to place a greater focus on mathematical and statistical modeling and to leverage more technology to enhance conceptual understanding. Stakeholders also called for a simpler, more concise document. This draft was presented to the state board in January of 2026.
In the second phase, the committee used public feedback collected in January and February of 2026 to refine their draft into a final set of recommended standards. This feedback was presented to the state board in March of 2026 and the committee used this feedback to produce the final set of recommendations that were presented to the state board at their April 2026 meeting.
The committee has produced draft recommendations for revised standards in response to this feedback. This most obvious changes are to the structure of the document. Below is a summary of changes to both the content and layout of the document:
- Length: The content of the final recommendations is 16 pages, compared to 67 pages in the 2018 document.
- Headings/subheadings: The draft recommendations has a 4-level structure (content area, grade level, standards "cluster," and standards), which is simpler compared to the 2018 structure (content area, grade level, standards category, prepared graduate statements, grade level expectations, evidence outcomes, academic contexts and connections, Colorado Essential Skills, mathematical practices, inquiry questions, and coherence connections).
- Groupings of standards: The draft recommendations organizes 147 standards into 19 groupings, compared to 193 evidence outcomes in 54 grade level expectations in the 2018 standards.
- Advanced content: The draft recommendations contains 89 "foundational" standards for all students, in addition to 20 to 25 advanced standards that each belong to one or more of three advanced pathways: quantitative reasoning, statistics, advanced algebra/calculus. The 2018 standards did not indicate pathways and used a single "+" sign to indicate advanced content.
- Supporting material: The committee and CDE proposes moving supporting material (examples, inquiry questions, coherence connections, etc.) to supplementary documents that are created and maintained separately from the standards documents and the standards review and revision cycles.
The committee was able to significantly reduce the length of the high school standards by moving supporting material out of the main standards document and reducing the amount of text used to describe what is expected of high school students.
