A series of reports by HUD’s Inspector General have found serious flaws in the implementation of the Moving to Work (MTW) housing demonstration, including ineffective oversight by HUD and poor use of funds by some local housing agencies. These findings, considered together with other risks posed by MTW, suggest that sharply expanding MTW’s size and scope — as some members of Congress are seeking to do — would be unwise. Instead, MTW could be improved by strengthening accountability while maintaining the demonstration at roughly its current size.
