OER evaluation frameworks

Overview of OER evaluation

Definition and scope of OER

Open Educational Resources (OER) are teaching, learning, and research materials that are freely accessible for use, modification, and redistribution. They typically rely on open licenses that permit adaptation, remixing, and sharing, enabling educators to customize content to local contexts. OER can include textbooks, course modules, lesson plans, videos, simulations, and assessment items, all designed to reduce barriers to education. The scope of OER extends beyond mere access to emphasize transparency, interoperability, and ongoing improvement through collaborative use and adaptation.

Rationale for evaluating open educational resources

Evaluating OER serves multiple purposes. It helps ensure educational quality, accuracy, and alignment with pedagogical goals. Evaluation also checks licensing clarity, accessibility for diverse learners, and the practicality of reuse in different instructional settings. By assessing sustainability, maintenance, and metadata practices, institutions can choose resources that remain viable over time and that integrate smoothly with existing systems. Ultimately, robust evaluation supports equitable access, improves learning outcomes, and strengthens the overall impact of open education initiatives.

Core evaluation frameworks

Common criteria used across frameworks

Across many evaluation frameworks, several core criteria recur. These include:

• Quality and accuracy: factual correctness, currency, and alignment with learning objectives.
• Reusability and adaptability: ease of modification, compatibility with different curricula, and freedom to remix.
• Licensing and openness: clarity of licenses, permissions for reuse, and permissiveness that supports stakeholder needs.
• Accessibility and inclusivity: compliance with accessibility standards, availability in multiple formats, and support for diverse learners.
• Metadata and discoverability: meaningful metadata, standardized classification, and easy searchability.
• Sustainability and maintenance: ongoing updates, version control, and long-term availability.
• Cultural relevance and inclusivity: representation of diverse perspectives and alignment with local contexts.

Notable OER evaluation models and guidelines

Several models and guidelines have shaped how institutions assess OER. Many are built around multi-criteria decision-making, quality assurance checklists, and licensing audits. Some frameworks emphasize pedagogy-driven outcomes, while others focus on technical interoperability, metadata standards, and accessible formats. While specific models vary by organization, the underlying goal is consistent: provide transparent, repeatable processes that help educators and administrators select, adapt, and improve open resources in ways that support scalable, equitable learning.

Evaluation criteria for OER

Quality and accuracy

Quality assessment examines the factual correctness, clarity of explanations, alignment with curricular standards, and the presence of reliable sources or references. It also considers the thoroughness of examples, the validity of assessments, and how well the resource supports the intended learning outcomes. Regular expert reviews and user feedback loops are valuable components of this criterion.

Reusability and adaptability

Reusability looks at modularity, ease of adaptation to different contexts, and the freedom to remix materials. Resources with modular units, open templates, and interoperable file formats enable teachers to tailor content without starting from scratch. Adaptability also encompasses cultural and linguistic customization to meet diverse student populations.

Licensing and openness

Licensing clarity ensures that users understand what they may legally do with a resource—whether it can be shared, modified, or repurposed for commercial use. Openness evaluates the degree to which licenses promote broad access and collaboration, rather than imposing unnecessary restrictions that hinder reuse or redistribution.

Accessibility and inclusivity

Accessibility checks whether resources meet universal design principles and accessibility standards, such as WCAG conformance, alternative text for images, synchronized captions, and screen-reader compatibility. Inclusivity considers language options, representation of diverse learners, and accommodations for those with disabilities or limited resources.

Metadata and discoverability

High-quality metadata enhances discovery and reuse. This includes clear titles, authorship, licensing terms, versioning, subject classifications, and keywords. Standardized metadata frameworks improve interoperability across repositories and learning management systems, making it easier for educators to find suitable resources.

Sustainability and maintenance

Sustainability addresses long-term viability, ongoing updates, governance, and a plan for updates in response to new standards or research. It also covers the resources needed to maintain links, fix broken assets, and ensure compatibility with evolving technology and platforms.

Methodologies for evaluating OER

Quantitative metrics (usage, impact)

Quantitative evaluation tracks indicators such as download counts, views, completion rates, adoption across courses, and changes in cost per student. Impact measures may include improvements in assessment performance, retention, or course completion, when data are available and ethically collected. Longitudinal studies help reveal how OER usage correlates with learning outcomes over time.

Qualitative methods (user feedback, expert reviews)

Qualitative methods gather insights from students, instructors, and instructional designers through surveys, interviews, focus groups, and open-ended feedback. Expert reviews provide professional judgments on pedagogy, content accuracy, and alignment with institutional standards. This rich data captures nuance that metrics alone cannot provide.

Mixed-methods approaches and multi-criteria decision analysis

Combining quantitative and qualitative data offers a holistic view. Multi-criteria decision analysis (MCDA) frameworks help weigh different evaluation criteria according to institutional priorities, such as equity, quality, or scalability. This approach supports transparent, reproducible decisions about which OER to adopt, adapt, or invest in for future development.

Case studies and practical examples

Higher education

In higher education, libraries and teaching and learning centers often lead OER evaluation projects. They may audit faculty-created open texts, benchmark against quality standards, and pilot OER in selected courses. A common approach is to establish a rubric that covers licensing, metadata, accessibility, and alignment with learning outcomes, then gather course-level data on student performance and engagement to inform broader adoption decisions.

K-12 and vocational training

For K-12 and vocational training, evaluation focuses on alignment with state or national curricula, accessibility for diverse learners, and the practicality of materials in classroom settings. Relevance to real-world tasks, language clarity, and availability of offline formats are particularly important. In vocational contexts, assessments should validate transferable skills and industry relevance, while ensuring resources support scalable training across different learning environments.

Practical guidelines for practitioners

Steps to implement an OER evaluation

To implement an OER evaluation, practitioners can follow a structured workflow:

• Define clear objectives and success metrics aligned with institutional goals and learner needs.
• Assemble a diverse evaluation team including educators, librarians, instructional designers, and students.
• Select evaluation criteria and develop a practical rubric or scoring framework.
• Collect data through a mix of surveys, interviews, usage analytics, and expert reviews.
• Analyze findings, identify strengths and gaps, and prioritize actions for improvement.
• Document results and communicate recommendations to stakeholders.
• Implement changes and establish a monitoring plan for continuous improvement.

Tools and resources for assessment and improvement

Effective assessment relies on a suite of tools and resources. Useful options include:

• Checklists and rubrics tailored to OER evaluation criteria.
• Metadata templates and controlled vocabularies to enhance discoverability.
• Accessibility evaluation tools and guidelines to verify format compliance.
• License verification resources to confirm open terms and reuse rights.
• Repositories and discovery platforms that support versioning and updated licensing information.
