Graduate Admissions for a More
Diverse Student Body

Acceptable Practices for Graduate
Admissions
 
Consider all applicants in the same admissions pool
 
Do an “individualized, holistic review” of each file to
identify candidates qualified for admission
 
Once a pool of qualified candidates is identified, then
select admits from that pool based on each
applicant’s contributions to the educational
environment
 
Diversity, broadly defined, can be considered, along
with other criteria at each step of the process
2
1
What is diversity?
 
Includes culture, socioeconomic status, race,
gender, ethnicity, sexual orientation, disability, work
and life experiences, skills, and interests
 
The School particularly encourages departments and
programs to seek applications from and to recruit
– 
– 
– 
– 
 
Underrepresented minorities (URM): African Americans,
Hispanic/Latino Americans and Native Americans
Women in the sciences
Low-socioeconomic backgrounds
First generation college students
A diverse student body will enhance the breadth,
depth, and quality of our educational environment.

ETS Guidelines for Using GRE Scores
 
Use multiple criteria
– 
letters of recommendation, courses taken and their rigor,
GPA, essays, GRE General and Subject Test scores
 
Consider Verbal, Quantitative, and Analytical Writing
scores as separate and independent measures
 
Avoid decisions based on small score differences
 
Do not use GRE cutoff scores
 
Question predictive utility of scores for your own
department: Conduct validity tests

Revised General GRE
 
Began in August 2011; first score reports won’t be
available until mid-November
 
New verbal question types with increased focus on
reading and analyzing text
– 
– 
 
Elimination of analogies and antonyms
Touted as benefit to students with diverse backgrounds
New scoring range for verbal and quantitative sections
– 
– 
From 200-800 to 130-170 in 1 pt. increments
Reason? Tendency to make too much of small score
differences with 200-800 range

Causes of Group Differences in GRE
Performance
 
Socioeconomic Status (family income and first
generation college status)
– 
– 
An ETS study of high scorers (750-800) found 90% had
fathers with graduate or professional degrees.
Only 4% had fathers who had NOT completed high school
(Penncock-Roman, 1994)

Causes of Group Differences in GRE
Performance
 
Racial and Gender Stereotypes
– 
– 
– 
– 
The threat of confirming negative stereotypes places an
additional evaluative pressure on minority test-takers and
women taking math-oriented standardized exams (Steele &
Aronson, 1995; Spencer, Steele & Quinn 1999)
Impacts strongest academic performers, not the weakest
Associated with increased load on working memory
Stereotype threat constitutes a type of measurement bias
that may complicate interpretation of GRE scores.

Group Differences in GRE
Performance
 
Use the tables in Appendix to consider within-group
percentile rankings
 
Consider the question, “if we have an applicant with
a 650 verbal score, what is the likelihood we will see
another applicant with a 650 verbal score or
greater?”
10

GRE Summary
 
GRE scores must be interpreted with care
– 
Consider within-group percentile rankings in addition to
national percentile rankings
 
Understanding the limitations of the GRE tests frees
you up to focus instead on the whole application
 
You need not discard an applicant solely on the
basis of a relatively low test score
11
The “Student in Context” Approach
 
Consider all aspects of the application
– 
 
past accomplishments, letters of recommendations,
research statement, writing sample, GRE, GPA and
contributions to diversity
Consider multiple GPA measures
– 
post-frosh GPA, GPA in major, GPA in courses relevant to
field of grad study

Faculty Reviewer for Diversity
 
Identify a faculty member to take another look at the
diverse admissibles…
 
Review applications (particularly letters of
recommendation and essays) for evidence of
opportunities available and extent to which applicant
took advantage
– 
– 
Who are the trailblazers in the pool?
Was summer research the only opportunity available to the
student?
13
Faculty Reviewer for Diversity
 
Look through apps for traits associated with success
that can’t be measured by the GRE
– 
persistence, multitasking ability, creativity, intellectual
curiosity, potential for productivity
 
Report results back to full committee, make
recommendations and draw attention to promising
applications
 
Full committee could consider applicants who are ‘on
the bubble’

GRE Scores
 
How well do they predict performance in graduate
school?
 
How significant are small score differences such as
100 points?

GRE Scores and Graduate
Performance
 
ETS studies find that
– 
– 
 
12-25% of variation in 1st year grad school GPA
can be explained by variation in GRE scores.
Less variation explained in time to degree, faculty
rankings of grad students or ratings of dissertation
quality
Thus 75% or more of variation in 1st year
GPA is unexplained by the General GRE

Factors Influencing Success in

Reasoning Ability (General GRE)
Motivation
SUCCESS
Creativity

Skills
Subject Matter Knowledge
(Subject GRE)
Financial
Support
Family Circumstances

Examinations?” (available from www.gre.org)

Do Small Differences on GRE Scores
Matter?
 
IF the general GRE explains at best 25% of variation
in first year GPA, leaving the lion’s share in variation
unexplained…particularly when it comes to other
performance measures such as time to degree or
faculty rankings…
 
THEN a gap of 100 GRE points between two
otherwise equally qualified candidates may not be
particularly meaningful
 
AND students can buy 100 points on the GRE if they
have $1500 for a good GRE prep course
