## Quality conditions

Open Educational Resources must meet a number of preconditions before they can be shared. These are:

1. The material has a subject specific quality

2. The material has an open quality

3. The material has a didactic-educational quality

4. The material is readable and, if applicable, editable by others [language, form, content].

5. The material is published in an adaptable format, so that others can easily reuse it

6. The material complies with the copyright rules for Open Educational Resources

7. The material is licensed with permission for reuse

8. The material should be published in a repository and provided with metadata so that it can be easily found.

Add. 2: The material has an open quality:

- In the material, do not mention course-specific data such as dates, lesson details, the name of the subject, etcetera.

- The material should be free of advertising.

- If the material is provided with a (project) logo, make sure it can be easily adapted/removed.

- Make sure the material has an attractive design.

- If there is video material, make sure that any assignments are placed at the end so that they can be easily cut.

- In the case of video material, place the contact details of the creators in the credits.

- Make sure that links are as reliable and durable as possible.

- Materials should comply with the A3C Accessibility standard for the web, including good readability: font type, font size, colour contrast. See Guidelines for Web Content Accessibility (WCAG) 2.1

- Ensure that the material does not use jargon and unclear abbreviations.

- Ensure that a conscious choice of formal or informal language is made throughout the material.

- Make sure the language in the material is clear and correct.

- Develop Open Educational Resources in Dutch or English.

Add. 5: The material is published in an adaptable format, so that others can easily reuse it.
Consider whether the material can be easily viewed on a PC, Mac, tablet or phone. If a pdf is used, it is wise to also make the texts available in .txt format, so that they can be easily reused. The formats that you can use depend upon the chosen repository.
Add. 6: The material complies with the copyright rules for Open Educational Resources
When you upload your material with a CC licence, you must ensure that your material is free of copyright. Therefore, create your material with original material combined with open content. That is, materials with a CC licence or with materials for which you have permission to reuse them.
If applicable, also include teacher guides and such, to maximise the reusability.
