| 27 | ## Regulatory Framework |
| 28 | |
| 29 | ### Who Must Comply |
| 30 | Section 508 applies to: |
| 31 | - **Federal agencies** — all ICT developed, procured, maintained, or used |
| 32 | - **Federal contractors and vendors** — ICT supplied to federal agencies must meet 508 standards |
| 33 | - Does **not** directly apply to private-sector companies unless they contract with the federal government |
| 34 | |
| 35 | ### The Revised Section 508 Standards (2018) |
| 36 | The 2018 refresh aligns Section 508 with: |
| 37 | - **WCAG 2.0 Level A and AA** — for web content, software, and electronic documents (E205) |
| 38 | - **WCAG 2.0 Level A and AA** — for authoring tools (E204) |
| 39 | - **Functional Performance Criteria** (Chapter 3) — for ICT with no documented exception |
| 40 | - **Hardware requirements** (Chapter 4) — for physical ICT (kiosks, printers, phones) |
| 41 | - **Support documentation and services** (Chapter 6) |
| 42 | |
| 43 | ### ICT Coverage (E101–E103) |
| 44 | The standards cover: web content · software · electronic documents · hardware (kiosks, copiers, phones) · video/audio · telecommunications · authoring tools · support documentation |
| 45 | |
| 46 | ### Exceptions (E202) |
| 47 | - **Undue burden** — when compliance imposes a significant difficulty or expense; must provide an alternative means of access and document the determination |
| 48 | - **Fundamental alteration** — when compliance would fundamentally change the nature of the information or function |
| 49 | - **National security systems** — systems operated by DoD/IC for classified activities |
| 50 | - **Back-office equipment** — equipment used only by maintenance or monitoring personnel |
| 51 | - **Legacy ICT** — ICT acquired/deployed before January 18, 2018, is exempt until altered or replaced (but must provide an equivalent facilitated access if possible) |
