Chem21Labs Accessibility Policy

Last updated (October 19, 2023)


Chem21Labs is committed to providing accessibility to our online content to all students. We strive to provide a learning platform that ensures individuals with disabilities the ability to independently acquire the same information, engage in the same learning activities and realize the same learning outcomes.


Chem21Labs is committed to full compliance with the Americans with Disabilities Act Amendment Act, (ADAAA) and Sections 504 and 508 of the Rehabilitation Act of 1973 which prohibit discrimination against persons with disabilities. As defined in these laws, a person has a disability if he or she has a physical or mental impairment that substantially limits one or more major life activity.


Chem21Labs follows guidelines regarding the design and development of online courses in a format that offers equitable access to the opportunities and the benefits afforded by technology-based courses. In compliance with Section 508, Chem21Labs strives to provide learning activities that are accessible to people with disabilities and are consistent with the W3C's Web Content Accessibility Guidelines (WCAG) 2.0. In addition, we encourage university professors to comply with the WCAG 2.0 guidelines when uploading resources to our platform that their own students will use.


Our goal is to deliver a quality learning experience to all learners and to observe an academic result that is consistent among diverse learners. The Timed Repetitive Quizzes (TRQs) and interactive TRQs (iTRQs) assignments include the option to extend the time on a per student basis. The interactive Tutorials and homework strive to accommodate the vast range of individual learning differences amongst our users. The online lab submission assignments are based on lab reporting criteria created by professors at participating universities - should the online format fail to permit the proper accessibility, accommodations will be made by the lab instructor / university professor.
