Personal Needs and Preferences

Personal Needs and Preferences (PNP) is a component of the AccessForAll framework (standardized in ISO 24751 and IMS AccessForAll) that provides a structured way to describe an individual learner's accessibility requirements and interaction preferences. A PNP profile specifies preferences across multiple dimensions: display settings (font size, color contrast, screen magnification), content modality preferences (text, audio, visual, sign language), tool and scaffold preferences (screen reader, text-to-speech, dictionary), and control preferences (keyboard navigation, switch access, voice control). When a learner logs into a system that supports PNP, their profile is loaded into the session and the environment automatically adapts — adjusting the visual presentation through CSS overrides, selecting appropriate content alternatives, and configuring available tools. PNP profiles are designed to be portable across different systems and platforms, enabling learners to carry their accessibility preferences with them.
