The University of Chicago boasts more than 70 Nobel laureates, and its math and economics departments are among the best in the world.</p>
<p>But for years, the prestigious South Side school apparently didn’t have an accurate count of its faculty, number of classes or educational spending.</p>
<p>That’s the university’s explanation for why it changed some of the figures it gave to U.S. News & World Report for the magazine’s ‘‘America’s Best Colleges’’ guide. Partly because of those changes, Chicago jumps from No. 15 to No. 9 in this year’s ranking, out Monday. Schools rarely move more than two or three places from year to year.</p>
<p>HIGHER EDUCATION</p>
<p>The new U.S. News & World Report college rankings rate these the top national universities:</p>
<ol>
<li>Princeton University</li>
<li>Harvard University</li>
<li>Yale University</li>
<li>California Institute of Technology
Massachusetts Institute of Technology
Stanford University (tie)</li>
<li>University of Pennsylvania</li>
<li>Duke University</li>
<li>Columbia University
Dartmouth College
University of Chicago (tie)</li>
</ol>
<p>The magazine says it was surprised to learn a university as prominent as Chicago hadn’t kept better track of its data – the school was keeping some records by hand. But the magazine accepted the changes.</p>
<p>Chicago was in the magazine’s top 10 five years ago, but its rank had been sliding since then. School officials acknowledge the drop prompted them to review their data – and they concluded Chicago was selling itself short.</p>
<p>‘Can be easily laundered’</p>
<p>‘‘We just were too casual about it,’’ said Michael Behnke, vice president for university relations. ‘‘I’m kind of embarrassed we didn’t catch it before.’’</p>
<p>Critics of college rankings contend such lists are unreliable because the magazine counts on schools to self-report many of the underlying figures. ‘‘They can be easily laundered,’’ said Lloyd Thacker, executive director of the Education Conservancy.</p>
<p>Thacker said he wasn’t speaking specifically of Chicago – whose admissions dean is also a critic of rankings. But, he said, ‘‘Is there a temptation to do that when the stakes are so high? Hell, yes. Are academics above that? Hell, no.’’</p>
<p>Chicago has faced alumni complaints about its ranking, and in February, three top administrators flew to Washington to talk to U.S. News & World Report executives. This year, the magazine says, Chicago allocated an additional $39 million in library expenses to a category of educational spending it submits to the federal government and the magazine. Chicago’s rank in a key category, assessment by other schools, rose this year with no change in how it is reported.</p>
<p>The school is well-regarded, but its intellectual atmosphere makes for a self-selecting applicant pool and a 40 percent acceptance rate. That’s much higher than peers, which weighs down its ranking.</p>
<p>‘‘When I eyeball the rankings, it has always struck me that [Chicago] is undervalued,’’ Kelly said. ''It was just an interesting coincidence to have them come in and say, ‘We don’t think we’re doing this right.’"
