ADAAG Commentary (Appendix)

The Committee recommends that the Access Board develop a comprehensive new commentary for the revised ADAAG. The Committee did not attempt to fully review or study existing "Appendix" language, or to draft new commentary language related to all revised ADAAG sections. However, the work of the Committee has created several sources of information that the Access Board should utilize in the development of the commentary, as follows:

  • Editorial Side-by Side. This      document was prepared by the Editorial Subcommittee to clearly separate      "scoping", "technical" and "other"      provisions in current ADAAG. The "other" text includes      commentary language in numerous locations, including examples, recommendations,      or explanations.
  • Committee Report- The December      1995 Final subcommittee reports contain the most comprehensive      accumulation of committee rationale for recommended revisions to current      ADAAG. In addition, some committee actions included specific      recommendations for commentary text.
  • Current ADAAG Appendix.      Portions of the current appendix will still likely be appropriate as      commentary for the revised guidelines.
  • Approved Committee Challenges.      Approved committee challenges (from February 1996) include a rationale for      the challenge, and some challenges included specific recommendations for      commentary text.
  • Harmonization and Editorial      Meeting Results. In a few cases, the committee made specific commentary      recommendations at the harmonization (July 1996) and Editorial (August      1996) meetings.
