Superior Publishers

Resources from Superior Publishers do not include advertisements, pop-ups, or content that distracts from the topic, concepts, or skills taught within the resource.


Strong Publishers

It is recognized that publishers must often include advertisements in order to fund the creation of content. Therefore, a resource can be considered strong if it includes 2 or fewer advertisements. Advertisements must be appropriate, and may not obstruct the use of the resource, or become an intrusion within its overall flow. Resources with advertisements that are not clearly marked, distract the user, or influence the user to focus on unrelated content are not considered Strong resources.

Superior Publishers

Strong Publishers

Resources from Publishers can be considered strong if authentication is not required to access the page's contents, but it is used in order to store progress or save user created work. While rare, there are exceptions that may influence a curator to harvest resources that require free login (e.g., limited resources available on a topic).

Superior Resources

Superior Resources are designed to provide an engaging experience for students, often making use of visual elements, sounds, animation, and multiple forms of media that capture students’ interest and attention.


Strong Resources

Resources can be considered strong if they express information primarily through text, but are written in a way that provides accurate and relevant information.

Superior Resources

Superior Resources are created using technology that makes use of modern web standards, and presents information in ways that recognize observed usability and user experience best practice. Information is up to date and reflects the current understanding of the topics or concepts.


Strong Resources

Resources can be considered strong if the website shows visible or functional signs of age, but information is up to date and reflects the current understanding of the topics or concepts.

Superior Resources

Superior Resources are primarily focused on topics or concepts typically expressed within curriculum or delivered during instruction. They support standards or skills that are addressed by the majority of educators in classroom settings.


Strong Resources

Resources can be considered strong if they can be applied to the typical curriculum with some modifications, or address topics that do not receive direct focus within instruction, but are commonly of interest to students.

Superior Resources

Superior Resources require little up-front explanation for use by teachers and students, and no training is required to support immediate use by students.


Strong Resources

Resources can be considered strong if use of the resource requires that students or teachers read and understand a short set of directions.

Superior Resources

A resource has superior alignment only if both of the following are true:

  • All of the content and performance expectations in the identified standard are completely addressed by the resource.
  • The content and performance expectations of the identified standard are the focus of the resource. While some resources may cover a range of standards that could potentially be aligned, for a superior alignment the content and performance expectations must not be a peripheral part of the resource.

Strong Resources

A resource has strong alignment for either one of two reasons:

  • Minor elements of the standard are not addressed in the resource.
  • The content and performance expectations of the standard align to a minor part of the resource.

This rubric is only applied to learning resources that have suggested alignments to standards.
This rubric follows the Achieve Rubric for Evaluating OER Objects: Rubric 1: Degree of Alignment to Standards

Superior Resources

A resource is rated superior for the utility of materials designed to support teaching only if all of the following are true:

  • The resource provides materials that are comprehensive and easy to understand and use.
  • The resource includes suggestions for ways to use the materials with a variety of learners. These suggestions include materials such as “common error analysis tips” and “precursor skills and knowledge” that go beyond the basic lesson or unit elements.
  • All resources and all components are provided and function as intended and described. For example, the time needed for lesson planning appears accurately estimated, materials lists are complete, and explanations make sense.
  • For larger resources like units, materials facilitate the use of a mix of instructional approaches (direct instruction, group work, investigations, etc.).

Strong Resources

A resource is rated strong for the utility of materials designed to support teaching if it offers materials that are comprehensive and easy to understand and use but falls short of “superior” for either one of two reasons:

  • The resource does not include suggestions for ways to use the materials with a variety of learners (e.g., error analysis tips).
  • Some core components (e.g., directions) are underdeveloped in the resource.

This rubric is only applied to resources designed to support teachers in planning or presenting subject matter.
This rubric follows the Achieve Rubric for Evaluating OER Objects: Rubric 3: Utility of Materials Designed to Support Teaching

Superior Resources

A resource is rated superior for the quality of its assessments only if all of the following are true:

  • All of the skills and knowledge assessed align clearly to the content and performance expectations intended, as stated or implied in the resource.
  • Nothing is assessed that is not included in the scope of intended material unless it is differentiated as extension material.
  • The most important aspects of the expectations are targeted and are given appropriate weight/attention in the assessment.
  • The assessment modes used in the resource, such as selected response, long and short constructed response, or group work require the student to demonstrate proficiency in the intended concept/skill.
  • The level of difficulty is a result of the complexity of the subject-area content and performance expectations and of the degree of cognitive demand, rather than a result of unrelated issues (e.g. overly complex vocabulary used in math word problems).

Strong Resources

A resource is rated strong for the quality of its assessments if it assesses all of the content and performance expectations intended, but the assessment modes used do not consistently offer the student opportunities to demonstrate proficiency in the intended concept/skill.


This rubric is applied to those resources designed to determine what a student knows before, during, or after a topic is taught.
This rubric follows the Achieve Rubric for Evaluating OER Objects: Rubric 4: Quality of Assessments

Superior Resources

A resource is rated superior for the quality of its instructional and practice exercises only if all of the following are true:

  • The resource offers more exercises than needed for the average student to facilitate mastery of the targeted skills, as stated or implied in the resource. For complex tasks, one or two rich practice exercises may be considered more than enough.
  • The exercises are clearly written and supported by accurate answer keys or scoring guidelines as applicable.
  • There are a variety of exercise types and/or the exercises are available in a variety of formats, as appropriate to the targeted concepts and skills. For more complex practice exercises the formats used provide an opportunity for the learner to integrate a variety of skills.

Strong Resources

A resource is rated strong for the quality of its instructional and practice exercises if it offers only a sufficient number of well-written exercises to facilitate mastery of targeted skills, which are supported by accurate answer keys or scoring guidelines, but there is little variety of exercise types or formats.


This rubric is applied to resources that contain exercises designed to provide an opportunity to practice and strengthen specific skills and knowledge.
