<p>The Power and Peril of Admissions Data</p>
<p>By ELIZABETH F. FARRELL</p>
<p>Inside Baylor University's admissions office, almost anything is quantifiable. When a high-school student calls, an admissions representative ranks the student as soon as he or she hangs up the telephone. Callers who happen to mention that Baylor is their top choice get a 1 (on a five-point scale). If they seem likely to apply, they receive a 2. Those who are not sure about Baylor, but are somewhat interested? They get a 3.</p>
<p>The university records and rates every bit of correspondence with each prospective applicant. This fall even student tour guides have begun to assign scores to high-school students who give any hints of interest in Baylor.</p>
<p>"We want to know if they mentioned something," says James Steen, Baylor's assistant vice president for admission and enrollment services, "like the fact that they're a third-generation legacy and they're not going to apply anywhere else, or if they were not that interested and just happened to stop by Baylor on the drive home after visiting UT."</p>
<p>Mr. Steen's staff enters this information into a database called Bearhaus, which allows admissions officers to keep track of all their communications with students. The database uses statistical models to interpret the numbers, assigning each student an overall score that tells Baylor how likely he or she is to apply, and later, to enroll.</p>
<p>The models also cross-reference demographics and information about a student's academic profile in assigning scores. That way, students who are highly sought after can be identified, sometimes so the college can recruit them more aggressively.</p>
<p>That score helps Mr. Steen and his staff make crucial marketing decisions. Potential applicants with the highest scores receive glossy, full-color brochures. Those who seem less interested may get only an e-mail message or a black-and-white postcard. With limited marketing dollars, the object is to keep the interest of those students who already have Baylor on their radar screens.</p>
<p>As colleges become more like businesses, with strict bottom lines, quantifying a potential applicant's interest in a particular institution has evolved into a science. Almost all colleges are scrambling more than ever before to meet net tuition-revenue goals, increase the geographical and racial diversity of their applicants, and lower their acceptance rates by attracting more applicants.</p>
<p>Until about five years ago, only a handful of colleges used sophisticated statistical formulas. But now there are few four-year institutions that do not.</p>
<p>Many admissions officials now rely on databases like Bearhaus to help them recruit and enroll each new crop of students. The use of statistics is vital in admissions, but it forces officials to walk a fine line between meeting quantifiable objectives and preserving their commitment to judging each student on his or her individual merits, which numbers do not always capture.</p>
<p>"We are the office of revenue and reputation," says Daniel M. Lundquist, vice president for admissions, financial aid, and communications at Union College, in Schenectady, N.Y. "When I started doing this, you could do it with a baseball bat. Now you need forceps. ... The stakes are astronomically higher."</p>
<p>Statistical models like Baylor's work by using the behavior of past applicants to predict how future ones will act. Those data are supposed to help admissions officials meet their enrollment goals, yet many officials say the scramble to collect more and more numbers has placed them on a hamster wheel that never stops spinning.</p>
<p>Furthermore, the same reams of data many colleges collect to simplify the admissions process may also skew their enrollment predictions. After all, if the formulas help colleges market more effectively to prospective applicants, officials will have more applications to wade through. The more applications a college receives, the harder it is to predict which students really want to go there, no matter how many statistics an admissions office has on each applicant.</p>
<p>"When will we say enough is enough and get back to good, old-fashioned admissions practices?" asks Monica Inzer, dean of admission and financial aid at Hamilton College, in Clinton, N.Y. "The transcript and what we value in an applicant should be what matters most, not whether or not a student visited campus."</p>
<p>'Funnels' of Students</p>
<p>As recently as 10 years ago, colleges tracked only a few statistics, including the grades, test scores, and geographic locations of prospective applicants. They would wait until students applied, then plug that information into a simple statistical model to get a reasonably close estimate of how many of their admitted students would enroll. Closely tracking data on high-school sophomores and juniors before they applied was unheard of at all but a few institutions.</p>
<p>During the last five years, however, the way many students apply to colleges has changed drastically, making the models most institutions use much less reliable than before. The number of high-school students applying to college is the largest in history, and those students are applying to more colleges than their predecessors did. And some admissions officers now struggle to predict their enrollment numbers because more students are acting as "secret shoppers," giving no hint of their interest in a college until they submit an application.</p>
<p>The less admissions officers know in advance about their final enrollment numbers, the more challenges they are likely to encounter. If they admit too many students, faculty members and residence-life officials will complain about strained resources. And if fewer students than expected matriculate, trustees and administrators will bemoan the lack of tuition revenue.</p>
<p>Those pressures have led colleges to identify the students they want to pursue long before colleges receive the students' applications.</p>
<p>Various organizations, including the College Board, ACT, and the National Research Center for College and University Admissions, compile vast databases with information on the demographics and credentials of millions of high-school students: their test scores, grade-point averages, intended majors, ZIP codes, extracurricular activities, and colleges in which they have expressed an interest.</p>
<p>Each criterion is known as a "funnel" that helps colleges customize the list of students they wish to recruit.</p>
<p>Don Munce, president of the admissions-research center, says colleges are buying more and more names each year. At large public universities, those lists can have between 50,000 and 150,000 names, and private universities on average purchase lists of about 20,000 names, according to Kevin W. Crockett, president and chief executive of Noel-Levitz, a higher-education consulting firm that advises more than 1,000 colleges a year on enrollment-management practices.</p>
<p>In the past, most admissions officers were more discriminating at the beginning of the recruitment process than they are today. Before the rise of the Internet, when colleges could send promotional materials only by traditional mail, postage costs limited the volume of correspondence. Purchasing 100,000 names in one year was unheard of because very few institutions could afford to send so many glossy brochures.</p>
<p>Even as e-mail and the Internet have lowered the cost of casting a wide net for potential students, more-sophisticated databases and formulas have made marketing efforts more efficient. Having 100,000 names of potential applicants is useless unless admissions staffs know which ones are worth the $3 cost of producing and mailing a viewbook.</p>
<p>The numbers are especially useful at large public universities with shrinking budgets and growing pressure to recruit out-of-state students, according to Rick Burnette, director of student-information management at Florida State University. Mr. Burnette's charge is to figure out which statistics the university should track, and how to interpret them. That Florida State created his position two years ago despite overall cutbacks affirms the high value the university places on evaluating admissions data, he says.</p>
<p>"We're a growing institution with more applicants, and we don't have a growing staff," says Mr. Burnette. "We have to do a lot more with the same resources we've always had, and it's incumbent on us to be as efficient as possible and leverage technology and information in our communications with students."</p>
<p>By tracking data on prospective students, Mr. Burnette has found which towns and high schools in Florida tend to produce the highest proportion of the university's applicants. So he has stepped up marketing to students in those areas. He has also increased the amount of marketing the college does in areas with many prospective first-generation college students, to help Florida State diversify its applicant pool.</p>
<p>At Wilkes University, in Wilkes-Barre, Pa., a similar statistical analysis led Mike Frantz, vice president for enrollment and marketing, to discover that students who listed skiing as one of their hobbies were more likely than others to attend Wilkes, even though the college does not have a ski team.</p>
<p>To attract more of those potential students, he changed the college viewbook five years ago to include a picture of a student skiing. He also added wording that described Wilkes as located "in the foothills of the Poconos," a mountainous region of northeast Pennsylvania known for its ski resorts.</p>
