IT professionals can expect to be asked to support accessibility checkers in the productivity suites they deploy. These tools (which may be built into the applications or may require add-ons to be installed) will identify parts of the presentations that are not compliant with ADA requirements. For example, they will identify missing metadata, missing navigation aids, missing alternative text on images, and other aspects of the files. Some aspects of the files (for example color contrast) cannot be checked via accessibility checkers and IT professionals will be asked to support other tools.
