RESEARCH: In Low-Income Schools, Parents Want Teachers Who Teach
By Brian Jacob and Lars Lefgren
In affluent schools, other things matter
Recent government education policies seem to assume that academic achievement as measured by test
scores is the primary objective of public education. A prime example is the
federal No Child Left Behind law, which requires schools to bring all of
their students to “proficient” levels on math and reading tests
by 2014. Many state accountability plans judge schools on the basis of
these tests alone, and some states and school districts are considering
tying teachers’ compensation to student test results. Yet education
historically has served a variety of functions (e.g., socialization, civic
training), and public support for music and art in school suggests that
parents value things beyond high test scores.
Are test scores the educational outcomes that parents
value most? We tackle this question by examining the types of teachers that
parents request for their elementary school children. We find that, on
average, parents strongly prefer teachers whom principals describe as best
able to promote student satisfaction, though parents also value teacher
ability to improve student academics. These aggregate effects, however,
mask striking differences across schools. Parents in high-poverty schools
strongly value a teacher’s ability to raise student achievement and
appear indifferent to student satisfaction. In wealthier schools the
results are reversed: parents most value a teacher’s ability to keep
students happy.
Data
This study combines data on teacher requests (by
parents) and teacher evaluations (by principals) from 12 elementary schools
in a midsized school district that asked to remain anonymous, in the
western United States. The students in the district are predominantly white
(73 percent), but there is a reasonable degree of diversity in terms of
ethnicity and socioeconomic status. Roughly 35 percent of the white
students are eligible for free or reduced-price lunch. Latino students, 84
percent of whom are eligible for free or reduced-price lunch, comprise 21
percent of the student population. Achievement levels in the district
nearly match the average of the nation (49th percentile on the Stanford
Achievement Test).
There is no formal procedure for parents to request
specific teachers in the district. Principals report that they assign
students to classes with an eye toward balancing race, gender, and ability
across classrooms within the same grade. Parents submit requests during the
spring or summer, and principals make assignments over the summer. During
our analysis period, roughly 22 percent of parents requested a teacher each
year and 79 percent of teachers received at least one parental request.
Parents are also able to request that their child not be placed with a particular
teacher (a “negative request”). Only about 9 percent of
teachers received any negative requests, and 92 percent of teachers with
negative requests had at least one positive request as well. Principals
report that they are generally able to honor almost all requests, giving
parents an incentive to truthfully reveal their first preference.
Parents in the district appear to have strong and
varied preferences for teachers. Among those teachers receiving at least
one request, the average number of requests was 6.2. Whereas the teacher at
the 25th percentile received only 2 requests, the teacher at the 75th
percentile received 8 requests. Moreover, there are often large differences between the
most-requested and least-requested teacher within the same school, grade,
and year: The average difference is 7.4, and in 10 percent of grades, the
difference is larger than 17.
Our data include information on requests made for the
2005–06 school year (the “request year”) in the summer of
2005 for kindergarten through 6th-grade teachers in all 12 schools in our
sample, as well as information from an earlier year for two of the schools.
We exclude from our analysis those teachers parents could not have
plausibly requested—mainly new teachers (unless parents specifically
requested the “new” teacher), who comprised about 17 percent of
those teaching in the request year. Note that we include teachers who did
not receive any requests, as long as they taught in the same grade and
school in the request year and the prior year. Our final sample consists of
256 individual teachers. Parents who made requests chose, on average, from
among approximately three different teachers.
With the assistance of the district, we linked the
parental request data to administrative data on teachers and students.
Because the administrative files provide only a very coarse measure of
family socioeconomic status—eligibility for the federal free or
reduced-price lunch program—we constructed an additional proxy for
family income by matching each student’s residential address to U.S.
Census data on the median household income in the student’s
neighborhood.
Finally, to supplement our information on teachers, we
administered a survey to all elementary school principals in February 2003
and March 2006. In these surveys, we asked principals to evaluate their
teachers along a variety of dimensions, including dedication and work
ethic, organization, classroom management, parent satisfaction, positive
relationship with administrators, student satisfaction, role model value
for students, and ability to raise math and reading achievement. The
average rating was roughly 8 on a scale of 1 to 10, indicating that
principals were quite lenient in their assessments. On the basis of these
survey results, we created three measures: (1) the principal’s
overall assessment of the teacher’s effectiveness, which is a single
item from the survey; (2) the teacher’s ability to improve student
academic performance, which is a simple average of the organization,
classroom management, reading achievement, and math achievement survey
items; and (3) the teacher’s ability to increase student
satisfaction, which is a simple average of the role model and student
satisfaction survey items. If a teacher was rated by the principal on both
the 2003 and 2006 surveys, we use the average of the two ratings.
In previous research using the 2003 principal survey
data (see “When Principals Rate Teachers,” research, Spring 2006), we found that
principals in the district are usually able to identify the most and least
effective teachers in their schools, as measured by their students’
academic progress. However, principals appear to be less successful in
differentiating between teachers near the middle of the distribution of
teacher effectiveness.
What kinds of parents make requests?
We begin by examining the characteristics of families
who make requests. This is important for two reasons. First, our analysis
of parent preferences will reflect only the views of those parents who
actually made requests, so it is important to understand this group.
Second, whether different types of families are more or less likely to make
a request has important implications. If high-income parents are more
likely to make a request, and such requests are for better teachers on
average, then the availability of requests could exacerbate the achievement
gap between students from low- and high-income families, even if all
families equally value academic achievement.
In this district, families that are not eligible for
the federal lunch program are about twice as likely to make a request as
those that are eligible: 30 percent of families who are not eligible for
free or reduced-price lunch make a request compared with only 13 percent of
eligible families. Interestingly, these fractions are nearly identical
across schools with very different poverty levels. Thus the socioeconomic
makeup of the school does not appear to affect whether parents make a request,
although the socioeconomic status of the family does.
We also conducted a more sophisticated analysis that
measures the relationship between a family’s demographic
characteristics (such as eligibility for free- or reduced-price lunch,
median household income of the student’s residential neighborhood,
race, and student prior achievement level), a school’s poverty level,
and the likelihood that the parent makes a request. These results confirm
that, conditional on the characteristics of the family and student, parents
in high- and low-poverty schools are about equally likely to make a request. However,
parents of low-income students are about 6 percentage points less likely to make a
request than parents of high-income students (9 percent vs. 15 percent).
Additionally, parents from high-income neighborhoods are about 4 percentage
points more likely to make a request than parents from low-income
neighborhoods (17 percent vs. 13 percent). Finally, Hispanic parents are
significantly less likely to request a particular teacher for their child
than are other families in the district.
After taking into account differences in socioeconomic
status, we found that parents of higher-achieving students are more likely
to make a request, which perhaps reflects greater sophistication or
interest on the part of these families. The parents of a student whose
performance is 1 standard deviation above the mean are about 8 percentage
points more likely to make a request than the parents of an otherwise
similar student whose performance is 1 standard deviation below the mean
(19 percent vs. 11 percent).
What kinds of teachers do parents request?
In general, parents who make a request exhibit a
strong preference for teachers who have received higher overall ratings by
the school principal. However, recall that the principals’ survey
responses allowed us to construct separate measures of two distinct aspects
of teacher quality: the ability to improve student achievement and the
ability to provide an enjoyable classroom experience for students. While
positively correlated, these two factors appear to reflect distinct
characteristics that vary across teachers. Overall, we find that parents
value the teacher’s performance on both the student satisfaction and
achievement measures, but give more weight to the satisfaction measure.
Even more interesting, however, we find stark
differences across schools in the type of teachers that parents tend to
request. We find that parents making requests in high-poverty schools place
less value on student satisfaction than those in lower-poverty schools.
Conversely, parents in high-poverty schools value a teacher’s ability
to improve student achievement considerably more than parents in
lower-poverty schools.
On the other hand, within a school, a family’s
own socioeconomic status is uncorrelated with the type of teacher a parent
requests. That is, both more- and less-advantaged parents in low-income
schools tend to request teachers that are rated highly in terms of their
ability to improve student achievement. In contrast, parents from all
backgrounds in higher-income schools tend to request teachers who are rated
more highly in terms of their ability to improve student satisfaction. When
we control for the socioeconomic status of both the student and school, our
findings are the same: student characteristics are not related to the type of teachers
that parents prefer, while school characteristics are strongly related to parental
preferences for teachers.
To quantify these differences, we used our results to
simulate parent choices (see Figure 1). For the sake of simplicity, we
first consider a situation in which a parent can choose between two
teachers: one teacher has an average rating for both achievement and
satisfaction; the other teacher has an average rating for achievement, but
a high rating on the satisfaction measure (i.e., a rating 1 standard
deviation above the mean). We calculate the percentage of parents with
average background characteristics who would choose the high-satisfaction
teacher. Next, we change one characteristic of either the parent or school
and calculate how this change would affect the percent of parents who would
choose the high-satisfaction teacher.

In a school where 80 percent of the children are
eligible for free or reduced-price lunch, the parents of the average child
would have a 48 percent chance of selecting the teacher with a
high-satisfaction and average achievement rating over the teacher with
average ratings on both satisfaction and achievement. In other words, these
parents are no more likely to choose the high-satisfaction teacher than if
they had randomly chosen which teacher to request. In contrast, if the
child attends a school where only 20 percent of the students are eligible
for free or reduced-price lunch, there would be a 65 percent probability
that their parents would select the high-satisfaction teacher. The 17
percentage point difference is large and statistically significant.
We then consider the scenario where the choice is
between two teachers who have the same satisfaction rating but different
achievement ratings, and see the opposite result. Parents in the
lower-poverty school are no more likely than they would be by chance to
select the teacher with a high achievement rating (51 percent), whereas
parents in the higher-poverty school would choose the teacher with a higher
achievement rating 62 percent of the time. Again, the difference of 11
percentage points is statistically significant.
As one might expect, parents of kindergarten children
appear to value satisfaction more and academics less than other parents,
though this difference is small and bordering on statistical
insignificance. Grade level is otherwise unrelated to preferences for
teacher attributes.
Parent requests and classroom effectiveness
It is important to emphasize that the results
presented above reflect both what parents observe and what they value. To
the extent that parents have less information on a particular teacher
characteristic, our findings may underestimate parent preferences for this
characteristic. In particular, one might be concerned that parents do not
have accurate information on teachers’ ability to raise student
achievement. For this reason, we focus primarily on information from the
principal survey, which likely reflects teacher behaviors or qualities that
parents might learn from observing the teacher’s classroom or
speaking with friends and neighbors who have had experience with the
teacher in the past.
To test the sensitivity of our results to this
methodological decision, we constructed a value-added indicator that
measures a teacher’s contribution to student achievement (accounting
for a wide variety of student and classroom characteristics that could
affect achievement independent of the teacher’s ability). We find
that teachers who perform better on our value-added measure also receive
more parent requests, even after controlling for the student satisfaction
measure from the principal surveys. However, when we also control for the
principal-reported academic measure, this relationship is no longer
significant, although the relationships between parent requests and both
principal-reported measures remain positive and significant. These results
suggest either that the academic considerations parents value are better
captured by principal ratings or that parents have difficulty observing how
much value a teacher adds to reading and math test scores.
An explanation?
The results presented above suggest that parents in
low-income schools strongly value student achievement and are essentially
indifferent to a teacher’s ability to promote student satisfaction.
The results are reversed for families in higher-income schools. At the same
time, we find that parent preferences within schools are identical across several measures of
family socioeconomic status. How should we interpret these results?
One possible explanation emphasizes the role of school
context in the educational process, particularly the interaction between
parents, schools, and students. In this view, high- and low-income parents
have similar preferences for student outcomes, but face constraints that
are correlated with school demographics. Because academic resources are
relatively scarce in higher-poverty schools (e.g., there are more
disruptive peers, lower academic expectations, fewer financial resources,
and less-competent teachers), parents in these schools seek teachers
skilled at improving achievement even if this comes at the cost of student
satisfaction.
If this explanation were true, we would expect to find
a positive association between school-level income and school-level
academic inputs, and a negative association between school-level income and
the differences in the value-added by teachers within the same school. The
second prediction is simply a consequence of diminishing returns to
academic inputs. More specifically, if the average quality of teachers in a
school is already high, being assigned to one of the better teachers will
have only a limited effect on student achievement.
To what extent are these predictions borne out in the
data? A comparison of observable teacher characteristics across schools
provides some support for the first prediction. As in most other school
districts, the teachers in higher-poverty schools in our sample have fewer
years of experience than their counterparts in lower-poverty schools (11.8
years vs. 14.0 years). In comparison to their counterparts, teachers in
higher-poverty schools are less likely to have credits beyond a
bachelor’s degree (66 percent vs. 78 percent) and are less likely to
have attended the most prestigious local university (75 percent vs. 80
percent) for their undergraduate degree. In addition, the variance of our
value-added measure is significantly higher within higher-poverty schools
than in lower-poverty schools, even after we control for the experience
level and other observable characteristics of teachers within each school,
which supports the second prediction. Hence, while certainly not
conclusive, the available evidence is consistent with the explanation
offered above.
Conclusions
Our findings suggest that what parents want from
school depends on the educational context in which they find themselves. In
particular, in low-income schools where academic resources are scarce,
motivated parents are more likely to choose teachers based on their
perceived ability to improve academic achievement. On the other hand, in
higher-income schools these parents seem to respond to the relative
abundance of academic resources by seeking out teachers who also increase
student satisfaction. This may reflect a parental preference for their
children to enjoy school, or it might reflect parental preferences for
teachers who emphasize academic facets that increase student satisfaction
but are not captured by standardized test scores, such as critical thinking
or curiosity.
In considering the policy implications of this
research, it is important to recognize that our analysis reflects parent
decisions conditional on school choice. In principle, students in this district
can attend any school, although in practice the vast majority of students
simply attend their neighborhood school. Because the school choice decision
is quite different from the teacher choice decision, our findings do not
map directly onto the school choice debate. However, the results
represented here do inform other policy issues. For example, they suggest
that the parents of low-income, minority, and low-achieving children are
much less likely to take advantage of informal opportunities to exercise
choice from among teachers. This highlights the potential adverse impacts
of honoring parental requests on the equitable distribution of education
resources. Our results also suggest that different socioeconomic groups are
likely to react quite differently to accountability policies, such as those
embodied in No Child Left Behind. In more affluent schools, parents are
likely to oppose measures that increase the focus on standardized test
scores at the cost of student satisfaction. More generally, programs that
increase the focus on basic skills or classroom management at the expense
of student enjoyment or other academic facets not measured on standardized
tests are likely to be unpopular in more affluent schools.
