• Broadening Participation Matters
• State of Physics
• Bridge Programs and their Key Features
• Admissions Criteria and Diversity
• Using Minimum Acceptable GRE
Scores Negatively Impacts Diversity in
STEM and does not select students with the most research potential
Broadening Participation
Matters
• US Demographics are changing rapidly
– Minorities represent 1/3 of the US population, but much less in
STEM jobs (e.g., ~5.4% of PhDs)
– Engage URMs in STEM to utilize all facets of the domestic talent pool, address brain drain
Broadening Participation Matters
• Diversity is an Asset
– Diversity enhances innovation
– Collective intelligence from diverse social skills
Physics is among the least diverse of the sciences.

Top Priority Actions
1) Increase undergraduate retention and completion via strong academic, social, and financial support.
2) Teacher prep, college prep programs, and
Transition to Graduate Study.
Admissions is typically a two-tier process for all fields
Research and leadership potential
Creativity, Innovation
Enthusiasm, passion for research
Diversity
http://frontporchdenver.com/wp-content/uploads/sites/2/2012/06/coin_toss.jpeg
Many reasons for this,
Admissions is only one http://www.phdcompletion.org/information/Executive_Summary_Demographics_Book_II.pdf
• Grades
– Grade Inflation undermines minority participation http://www.gradeinflation.com/tcr2010grading.pdf

• Test Scores
– “Guide to Use of Scores” not followed (or even known of)
– Significant race/gender group differences
– Correlations with Success are questionable
Folder A
GRE-Q: 740 (80%)
Folder B
GRE-Q: 800 (perfect)
http://www.ets.org/gre/institutions/scores/guidelines/
From ETS Guide to Use of Scores:
It is an inexact measure ; only score differences that exceed the standard error of measurement of a given score can serve as a reliable indication of real differences in applicants' academic knowledge and developed abilities.”
Translated to physics-ese:
CONSIDER INSTRUMENT RESOLUTION
S.E.M. ~60 points (on old GRE scale, 200-800).
740 = 800 = perfect!
• About 180 graduate programs are listed in the AIP Graduate Programs book
– ~96% require the General GRE
• about one quarter of these have a stated minimum score for admission, with the median being 700 (~64%)
– ~48% require the Physics GRE
• about half of these have a stated minimum score for admission, with the median being 600 (32%).
From ETS Guide to Use of Scores
Guidelines
– A cutoff score based only on GRE scores should never be used as a sole criterion for denial of admission.
– Any department considering the use of a cutoff score should compile a rationale justifying the appropriateness of such a score for each measure:
(1) evidence that the proposed cutoff score for the measure usefully distinguishes between individuals who are likely to succeed in graduate school and those who are not, and
(2) the impact of the proposed cutoff score on the institution’s goals related to diversity. http://www.ets.org/gre/institutions/scores/guidelines/

• Nearly independent of intended graduate major
• Qualitatively unchanged when controlling for undergraduate GPA
• Qualitatively the same for
•GRE Subject test
•SAT Math
•8 th grade math achievement tests
•4 th grade math achievement tests
• A feature of standardized testing.

• Cut-off scores are used all the time by admissions committee members.
– Sorting spreadsheets is easy.
– Faculty are busy, often reluctantly serving
– Faculty are not trained in selection
– “Low scores must tell you something.”
• But correlation R~0.2-0.3 is only with first year
GPA; by second year, R<0.1

Subject Test may tell you a little about preparation , convolved with R/E/G
NOT about potential to become a
PhD-level research scientist (the aim!)
The usual weight given to
GRE scores in admissions exceeds its predictive capabilities and has negative societal impact.
• But it can, if you’re: careless; too busy; or just going through the motions.
• Lowering the bar perpetuates stereotypes exactly by definition
• What bar? Potential for what?

“Cognitive ability and knowledge are threshold aspects of professional work, necessary but not sufficient for outstanding professional performance.”
• Non-cogs considered after using filters that negatively impact diversity
• Measurable!
• Results from decades of Industrial-
Organizational Psychology research
– non-cogs predict academic/job performance
– non-cogs show little if any group differences
– non-cogs are orthogonal variables to cognitive constructs (GPA, SAT/GRE)
• ill-defined protocols = haphazard review
– Extra/Zero scrutiny for underrepresented folks
• Coarse Grained Rubrics
– can be implemented now!
– guides review of statements/letters/interviews
• can expedite the review process
• reduce implicit bias ( expectations based on race/gender/name/culture); combats reviewer fatigue
– inter-rater reliability
– develop in conjunction with a social scientist
– add short answer items on app to probe non-cogs?
http://www.vanderbilt.edu/gradschool/bridge/tools.htm
• Situational Judgment Tests
– could be implemented as part of the online application submission process (ease of use!)
– ask the test taker to describe how they would act in a hypothetical scenario; or rank the efficacy of several potential actions
– can be tailored to probe specific constructs or discipline-specific scenarios (hire an expert)
– susceptible to faking
– not terribly expensive
• Normalize components
• Add them
• More effective and efficient than nonalgorithmic methods
• non-cogs are orthogonal to cogs
– weight these equally http://en.wikipedia.org/wiki/Apgar_score
• Traditional admissions process
– No better than a coin toss
– Strongly filters under-represented groups
• Large race/gender gaps on standardized tests
• Grade inflation lowest at state universities
• Non-cognitive assessments can help
– increase the diversity of the applicant pool
– select students who will graduate
• Systematic evaluation protocols can
– limit implicit bias, increase diversity
– increase efficiency of screening applicants
• Get a social scientist to help!
