How We License Our Curriculum

Thanks to generous philanthropic support, we provide our superb curricula to districts at no cost by publishing them as Open Educational Resources (OER).

What You Should Know About OER Curriculum

1. The materials are free.
OER are freely available materials that can be downloaded, edited, and shared to better serve all students. OER license types vary: some OER allow free download and use, while others also allow adaptation.

2. The materials can be used flexibly.
We publish our curricula with a CC BY license—the most accommodating license—which lets users distribute, remix, tweak, and build upon our work, as long as they credit Open Up Resources for the original creation. Learn more below.

3. The materials are designed to be used in both print and digital versions.
The digital and print versions of our curriculum are the same, allowing districts flexibility in implementation: fully digital, to maximize cost savings in 1:1 classrooms; fully print; or a mix of print and digital.

We offer high-quality, affordable print materials for districts choosing to use them.

Frequently Asked Questions

I thought OER was supplemental material—is this really a core curriculum?
Yes, all of our materials are comprehensive core curricula.

How can I know that something free is still high-quality?

We agree with top district leaders: regardless of the cost of curriculum, quality is the benchmark. Learn how we partner with expert authors to raise the bar for curriculum here.

Districts deserve third-party quality assurance; in addition to our own review processes, we submit all our materials for review by nonprofit curriculum review site EdReports. Reviews of Open Up Resources 6–8 Math gave it near-perfect marks, making it top-rated by EdReports.

How much will we save when using free curriculum?

While the curriculum is free, educators know that implementing a new core program requires an investment. We provide more detail on the savings you can expect from OER curriculum here.  

How do you make money?

We’re a nonprofit organization. Our goal is improved teaching and learning, rather than profit; as our CEO recently told The Wall Street Journal, “We would like nothing more than to change the [curriculum] market to focus on learners’ needs rather than shareholder value.”

That said, a small portion of the revenue generated from optional services goes to support our ongoing operations, including continuous improvement of our curricula.
