On March 17, 2005, OCR announced a clarification of prong three of the three-part test of Title IX compliance. The guidance concerned the use of web-based surveys to determine the level of interest in varsity athletics among the underrepresented sex. Opponents of the clarification – including the NCAA Executive Committee, which issued a resolution soon afterward asking Association members not to use the survey – claimed the survey was flawed in part because of the way it counted non-responses. On April 20, 2010, the U.S. Department of Education's Office for Civil Rights abandoned the 2005 clarification that allowed institutions to use only Internet or e‑mail surveys to meet the interests and abilities (third prong) option of the three-part test for Title IX compliance.
