Names, Expectations and
the Black-White Test Score Gap
David Figlio
University of Florida and NBER
Introduction
• Blacks and Whites differ dramatically
along a wide range of outcomes
• Education is no exception:
– Black-White test score gaps exist at the
beginning of school
– These gaps expand as children get older
– No shortage of explanations for this pattern
The role of teacher expectations?
• Recent experimental evidence (Bertrand
and Mullainathan, 2004) supports the
notion that Blacks are differentially treated
in the labor market, even by firms that
advertise equal opportunity
• Might subtle biases exist among teachers
as well?
Field evidence from social
psychology
• Several important studies conducted in the
1970s (Coates, 1972; Feldman and
Orchowsky, 1979; Rubovits and Maehr,
1973; Taylor, 1979)
• Consistent finding: teachers take Black
students less seriously than they do Whites
Questions regarding field
evidence
• Are similar behaviors to the one-time laboratory
encounters found in the classroom, with frequent
interaction and feedback?
• Are results from the 1970s still relevant several
decades later?
• Presuming that teachers still treat Black children
differently in 21st century classrooms, is this
differential treatment related to “Blackness” per
se, or to some factor like low socio-economic
status?
Do expectations matter?
• Recent work on teacher grading standards (e.g.,
Betts and Grogger, 2003; Figlio and Lucas, 2004)
suggests that high expectations make a difference
• Psychology research on teacher perceptions
(Jussim et al, 1976) suggests that teacher
perceptions impact student outcomes
• Key question: Do student-specific factors
influence teacher perception/expectation
formation?
Purposes of this paper
• Empirically document the degree to which
teachers treat children differently in the
classroom
• Investigate whether this differential treatment is
associated with student outcome differences
• Employ a quasi-experimental research design in a
large-sample setting that
– Reduces the confounding role of unobserved variables
– Allows for heterogeneous treatment effects
Implementing experimental
design on a large scale
• Ideal situation would be to randomly
assign children to teachers, and follow
children from year to year across multiple
teachers
• Problems with this approach:
– Schools don’t do this
– Even if they did, non-compliance could
dramatically affect estimates (see, e.g., Ding
and Lehrer, 2003)
An alternative approach:
Within-family comparisons
• Rather than follow children over time across
different settings, instead study children crosssectionally and assume that many of the
important unobserved variables (e.g., student
motivation or self-concept, family support) are
invariant within a household
• This is potentially problematic…more in a little
while…
But…
• Isn’t race (or SES) constant within a
household?
• (Or, put differently: When race is NOT
constant within a household, do we
honestly believe that the children identified
as Black and White within a household are
alike on unobservables??)
A solution: Names
• Recent work in psychology (e.g., Rosenthal,
Pelham, Shih) suggests that names influence selfperceptions and others’ perceptions about a
person, as well as personal decisions
• Considerable within-family variation in the types
of names given to children (especially in Black
families)
• Do teachers form different expectations of Black
(and White) children based on their names?
Is a name link plausible?
• In one large Florida district:
– Black-White test score gap increases by 32%
from third grade to ninth grade
– In third grade, 5% of the gap can be explained
by different naming patterns
– In ninth grade, 16% of the gap can be
explained by different naming patterns
– Are these relationships causal??
This paper
• Detailed data from a large Florida school district
• 164,000 children from 72,000 families, 1994-95 through
2000-01
• For kids born 1989 to present, I merge data with birth
certificates, so I have mom’s education, birth weight,
labor/delivery complications, prenatal care indicators
• Test the hypotheses that
– Teachers and administrators expect less from children with Black
racially-identifiable names or other names that may connote low
socio-economic status
– These diminished expectations in turn lead to students
performing less well on standardized tests
How to measure expectations?
• I want to measure expectations based on teachers’
observed treatment of children
• However, there are many unobserved variables
(such as motivation, self-perception, peer
behavior, etc.) that are correlated with observed
teacher treatment
• My solution: Find two teacher treatment
variables that are highly positively correlated, but
where an expectations story would have them
moving in opposite directions
Two measures of expectations
• Conditional on test scores, I consider
expectations to be low if:
– Students are more likely to be “socially promoted”
– Students are less likely to be classified as gifted
– Promotion and gifted status are EXTREMELY highly
correlated, so a prediction of low expectations leading
to a divergence in these two outcomes is a very strong
one
– Importantly, other plausible explanations for outcome
patterns (e.g., racial identity explanation) DO NOT
suggest that these variables move in opposite
directions
The problem with sibling
comparisons
• Of course, you should be concerned that
family assignment of names to children is
non-random, and transitions in naming
patterns may reflect transitions in
affluence, segregation, identity, etc. that
could affect both names and parenting in
ways unobservable to the researcher.
Refinement of sibling
comparison
• I will, in turn, only look at siblings who:
– Share the same mother and father
– Are born within two years of one another
– Are twins (small n)
Preview of findings
• Children with low-SES names are treated
differently from their siblings with more
homogenized names at school
• They tend to score less on tests than do
their siblings
What’s in a name?
• Linguistic analysis of names led to identification
of four attributes of low SES:
–
–
–
–
Certain prefixes
Certain suffixes
Presence of apostrophe
Combination of long name and exotic consonants used
– The more of these attributes present, the more likely
that the mother is a high school dropout
Attributes of families with certain
names
The families of children with NO low-SES
attributes are:
32% maternal dropouts
57% on Medicaid at time of birth
53% married at time of birth
19% with teenaged mother
41% Black
Attributes of families with certain
names
The families of children with ONE low-SES
attribute are:
38% maternal dropouts
68% on Medicaid at time of birth
37% married at time of birth
28% with teenaged mother
62% Black
Attributes of families with certain
names
The families of children with TWO low-SES
attributes are:
49% maternal dropouts
86% on Medicaid at time of birth
14% married at time of birth
42% with teenaged mother
96% Black
Attributes of families with certain
names
The families of children with THREE OR
MORE low-SES attributes are:
55% maternal dropouts
90% on Medicaid at time of birth
6% married at time of birth
52% with teenaged mother
98% Black
Examples of names
•
•
•
•
•
One attribute: Damarcus
Two attributes: Da’Quan
Three attributes: Da’Nayvious*
Four attributes: Da’Qwinzzis*
Most popular low-SES name given to Whites:
Jazzmyn, Chloe’ and Zakery
• Names given to fewer than 10 children and
therefore not mentioned explicitly in paper
Within-family transitions in names
• Among families where the first child had no low-SES
name attributes, 12% of succeeding same-sex siblings had
a low-SES name
• Among families where the first child had at least one lowSES name attribute, 18% of succeeding same-sex siblings
had a low-SES name
• For Black families, these percentages are 16% and 25%
• For families with a high school dropout mother, these
percentages are 12% and 19%
• Considerable name-mixing exists between first and
middle names as well, for the same child!

Name attributes and test scores
• Estimated effect of changing names:
• Drew to Dwayne: -0.68 pct pts math, -0.74 reading
• Dwayne to Damarcus: -1.10 pct pts math, -1.17 pct pts
reading
• Damarcus to Da’Quan: -0.73 pct pts math, -0.78 pct pts
reading
• Da’Quan to Da’Qwinzzis: -0.66 pct pts math, -0.70 pct
pts reading
• Very similar results if count attributes rather than relying
on empirical predictions of low SES
• Evidence that “Blackness” of a name matters somewhat,
but SES of the name matters much more
Children born to same father within
two years of one another
• Estimated effect of changing names:
• Drew to Dwayne: -0.52 pct pts math, -0.76
reading (not statistically significant)
• Dwayne to Damarcus: -1.00 pct pts math, -1.47
pct pts reading
• Damarcus to Da’Quan: -0.66 pct pts math, -0.99
pct pts reading
• Da’Quan to Da’Qwinzzis: -0.60 pct pts math,
-0.88 pct pts reading
The ultimate sibling sniff test:
Twins
• 616 pairs of twins
• Very little exploitable variation in names
because of similarity in names given to
twins, but there are a few cases of very
different names given to twins, e.g.,
– Lakeisha and Laura
– Nicholas and Shanicholas
– Monica and Demonica
The ultimate sibling sniff test:
Twins
• Estimated effect of changing names:
• Drew to Dwayne: -4.11 pct pts math, -1.81
reading (only statistically significant in math)
• Dwayne to Damarcus: -1.77 pct pts math, -3.46
pct pts reading (stat sig in reading)
• Damarcus to Da’Quan: -1.20 pct pts math, -2.40
pct pts reading
• Da’Quan to Da’Qwinzzis: -1.08 pct pts math,
-2.16 pct pts reading
Names and teacher expectations:
GIFTED REFERRAL
• Estimated effect of changing names:
• Drew to Dwayne: 0.5 pct pts
• Dwayne to Damarcus: -1.9 pct pts
(significant)
• Damarcus to Da’Quan: -1.3 pct pts
• Da’Quan to Da’Qwinzzis: -1.2 pct pts
Names and teacher expectations:
PROMOTION
• Estimated effect of changing names:
• Drew to Dwayne: 1.1 pct pts (marginal)
• Dwayne to Damarcus: 1.4 pct pts
(significant)
• Damarcus to Da’Quan: 1.0 pct pts
• Da’Quan to Da’Qwinzzis: 0.9 pct pts
Teachers, administrators, and
peers
• School administrators may also be responding to
names, and can’t distinguish their responses from
teacher responses—but that’s immaterial for my
story
• Peers may also respond to names, and form
friendships and social groups on this basis. I am
currently collecting data on the formation of
playground friendships, and will address this in
future work
Asian families as an alternative
• Expect signs to flip
• Long or Vivek has GPA | test score estimated
0.05 (p=0.21) lower than Asian named Alexander
or Charles
• Gifted result: 0.11 (p=0.00) higher
• Test scores: 4 pct pts (p=0.16) higher
• No apparent relationship re: promotion, though
this may be because almost no Asian student ever
repeats a grade
Heterogeneity across schools
• I hypothesize that name-based expectations
should be less pronounced in schools with
– Larger numbers of Black students
– Larger numbers of Black teachers
Black teachers
• The results are stronger in schools with fewer
Black teachers: (e.g. Damarcus vs. Dwayne)
– Math test score: Few Black teachers: -1.21 (0.56),
more Black teachers –0.29 (1.10)
– Reading test score: Few Black teachers: -2.03 (0.51),
more Black teachers 0.28 (0.95)
– Promotion: Few Black teachers: 1.6 (0.7), more Black
teachers 0.9 (1.3)
– Gifted: Few Black teachers: -2.5 (0.9), more Black
teachers –0.2 (1.4)
Conclusions
• One mechanism through which the widening of the
Black-White test score gap over the school cycle occurs
may be due to teacher and school expectations—possibly
leading to Black children learning less in school
• Extra exposure reduces this pattern, and also reduces the
likelihood of apparent name-based treatment differences
• Results suggestive that teachers are responding to a raceperceived class combination when forming expectations
• Role for professional development and teacher training?
