<p>dt123, I want to thank you for posting that GAO report -- I think that provides a definitive answer to the OP's question. </p>
<p>I have gone through it and have excerpted relevant parts below that I think are especially pertinent, with page references based on the PDF numbering. Here's the full report title & link:</p>
<p>GAO Report to Congressional Committees, September 2006
"HIGHER EDUCATION
Schools Use of the Antitrust Exemption Has Not Significantly Affected College Affordability or Likelihood of Student Enrollment to Date"</p>

We found virtually no difference in the amounts students and their families were expected to pay at schools using the exemption compared to similar schools not using the exemption. Average expected family contribution (EFC) for students accepted at schools using the exemption was $27,166 and for those accepted at comparable schools not using the exemption was $27,395 in school year 2005-2006 ....</p>
<p>we found that the variation in the EFC for a student who was accepted to several schools using the exemption was similar to the variation in EFC that same student received from schools not using the exemption. The variation in EFCs for these students was about $6,000 at both sets of schools. ...</p>
<p>For example, seven schools chose not to use the consensus method for considering home equity.

We also found that low income students at schools using the consensus approach, compared to those at schools not using the consensus approach, received a significantly higher amount of total aid, which includes both grants and loans. However, the amount of grant aid that these students received did not significantly change, which suggest they likely received more aid in the form of loans, which they would need to repay. Additionally, implementing the consensus approach did not affect the likelihood of low-income or minority students enrolling at schools using the consensus approach compared to schools that did not.

Twenty-five of 28 schools implemented the consensus approach; 3 did not. While 13 schools implemented all the elements of the consensus approach, the remaining schools varied in how they implemented the methodology. As shown in table 4 below, seven schools chose not to use the consensus approach method for accounting for family loan debt, home equity, and family and student assets.

Among schools that partially implemented the consensus approach, many explained they did not fully implement the new methodology because it would have been too costly.
