Tests don’t even predict grades well
Tests don’t add anything to prediction
Tests don’t predict anything other than grades
Cognitive tests only predict academic outcomes
Cognitive tests are only proxies for SES
Beyond a certain point, scores don’t matter

– Personal Statements

Assertion:
Tests Don’t Even Predict
Grades Well
What does “well” mean and how do we quantify it?

Tests and Grades
• Berry and Sackett (2009) examined SAT-grade r’s in
a sample of 165,000 students from 41 schools
• Corrected for restriction of range using schoolspecific applicant pools
• Obtained individual course grades for each course,
and computed validity for each course (148,072
validity coefficients)
– This removes influence of student choice of courses
– Estimate r between SAT and common course portfolio

If the critics were right….
Book Smarts vs. Street Smarts
or
Academic vs. Practical Intelligence
or
Book Learning vs. Common Sense
Book Smarts vs. Street Smarts
• Fundamental argument is that different
types of intelligence are needed in
academic versus real world contexts
• It is argued that academic contexts require
an “academic intelligence” or book smarts
• It is my belief that these arguments are
based (in part) on an overly narrow
conceptualization of the tasks that
comprise academic performance
Academic versus Practical Tasks
•
•
•
•
•
•
Academic
Formulated by others
Well-defined
Presents complete
information
Single method for
obtaining answer
Not embedded in
ordinary experience
Little or no intrinsic
interest
•
•
•
•
•
•
•
Practical
Requires problem
recognition and
formulation
Ill-defined
Requires information
seeking
Multiple acceptable
solutions
Multiple paths to solution
Embedded in ordinary
experience
Requires motivation and
personal involvement

Cross-Situational Validity:
A Direct Test
• However, we still lack a direct test:
– Examine the validity of a single test developed
for academic settings but used in both
academic and work settings
– Ideally we would also establish the relationship
between this test and other cognitive ability
measures
• Unfortunately, a single ability measure is
rarely used for both personnel selection and
educational admissions decisions
• With one notable exception….

Story:
Predictive Power of Cognitive Ability
Tests is an artifact of SES
Its Storytime…
• In the interest of truth in advertising, the SAT
should simply be called a “wealth test” - Guiner
(Undated)
• “The SAT merely measures the size of
student’s houses” - Kohn (2001)
• “Only thing the SAT predicts well now is
socioeconomic status” – Colvin (1997)
Recent Claims in the
American Psychologist
• “…SAT I scores lose any ability to predict freshman
year grades if the regression analyses control for
socioeconomic status” (p. 100) – Crosby, Iyer,
Clayton, and Downing (2003)
• “…SAT scores used for college admissions do not
predict freshman year grades when socioeconomic
status is controlled” (p. 1023) – Biernat (2003)
• Atkinson and Geiser (2009) claim that SAT
coefficients are “decisively diminished” when SES
and HSGPA are controlled.

really high test scores and they didn’t
do as well as another friend who had

matters to a certain degree, right?”

Cautionary Tales
• Faking and Coaching
– Most alternatives that have been proposed
would be highly susceptible to deliberate faking
or test preparation coaching
• Personality Assessments
– Other ratings
• Study habits, attitude, and skill inventories
– Placement and guidance
• Biodata
– Verifiable content
• Situational judgments tests
Fairness and Bias
• Extensive research on standardized test
scores for bias
• Social class has also been scrutinized.
• Data for letters of recommendation and
personal statements in academic settings is
thinner.
• A summary of current knowledge on the next
slide…
New Alternatives Should be
Subjugated to Extensive Study for
Bias Before Implementation
