The Department of Human Services shall, at a minimum, review the accessibility standards every 3 years after the date of initial publication and, as appropriate, amend the standards to reflect technological advances or changes in electronic and information technology. The Secretary of Human Services may convene a working group of appropriate State entity representatives, stakeholders, and other appropriate individuals and officials to advise and assist in the process of reviewing and amending the standards. Within 6 months after the publication by the Department of Human Services of amendments to the standards, the Director of Central Management Services and other State entities shall review the amended standards and make any necessary changes to their existing procurement policies and procedures to incorporate amendments to the accessibility standards into their procurement policies and procedures. The amended accessibility standards shall apply to electronic and information technology developed or procured by a State entity, or to substantial modifications made to electronic and information technology by a State entity, after the Department of Central Management Services and other State entities incorporate the amended accessibility standards into their procurement policies and procedures.
