Choice-based reforms are anchored on
the idea that parents will have the power to make schools more responsive to
them if they will have the ability to choose among these institutions since
their choices determine enrolments and budgets. The main issue to this view
centers around how and what kind of schools parents select. Little, however, is
known on how they go about this course of action.
Aside from the method of choosing,
school choice reforms also question school effectiveness, finance, student peer
groups, and pupil achievement. Other questions are addressed to determine if
choice schools offer high-quality education as suggested by test scores, college
attendance, and other measurements. It is ambiguous, however, how choice
schools yield higher achievement scores or greater school efficiency. It remains to be revealed how schools react
to the pressure that is imposed by parents.
Proponents and opponents of
choice-based school reforms both use survey results to support their arguments
by citing school attributes. Such evidence, however, is problematic because of
the selection problem and the difficulty of eliciting truth from surveys with
regards to preferences. The first one may offer misleading evidence for the
prediction of the impacts of school choice policy since schools and parents may
not be representative of the population. The latter comes from the complexity
encountered in setting up realistic choices.
The answer to the question of how
parents choose schools is challenged by four obstacles.
1. The selection problem.
2. The requirement for objective evidence.
3. The choice programs are determined with other policies.
4. The need to differentiate between the effects of student
segregation and the effects of giving more influence to parents’ preferences.
The strategy of the author includes
identifying disparities in the number of school districts by using topographic
differences among metropolitan areas. This classifies exogenous differences in
the degree of school choice among public school districts. Generous data on
schools and pupils are used to obtain objective measures of behavior to verify
subjective descriptions of school attributes. Data from the National Education
Longitudinal Study (NELS) are used. Demographic data from the Public School
Universe and the special school district tabulation of the 1990 census are also
utilized to determine the impacts of segregation from the impacts of school choice.

II. The Interaction of Parents’ Preferences and School Choice
There are variations in the preferences
among and between parents and teachers. The teaching methods of parents and
teachers diverge most of the time because they have varying educational
backgrounds. Teachers lean towards unpopular teaching styles with conservative
parents. Also, parents favour teaching and disciplinary methods that are costly
in terms of teacher effort, while teachers prefer methods that are costly on
the basis of parent effort.
School choice impacts how the parent
preferences are transmuted into school attributes within parent-teacher groups
and between them; it will let more variation in preferences to be revealed.
But, the predicted rise in variation of school traits is not the central
concern of the study. Rather, the mean impact of school choice on curriculums
and atmosphere in schools will be the focus of the discussion. If average
parents like weaker standards than by the staff of the school, greater choice
will lead to the fall of academic standards. Conversely, if average parents
favour higher standards than by the staff of the school, greater choice will
enhance academic standards.
III. Data
Extensive information on curricular and
extracurricular activities is required for an empirical study on school
attributes that parents prefer. Data must depict the decisions of individual
schools and describe the environment where the school operates. Such precision,
however, is not available on any source. As such, information about the student
body and the community of each school district in the United States was derived
from the National Education Longitudinal Study (NELS) and was matched with the
Public School Universe and the special school district tabulation of the 1990 Census
of Population and Housing.
The Public School Universe has
administrative data on the pupils in each school and district. Educational
attainment, household income, age, and house value were derived from this
dataset. The NELS, on the other hand, is
comprised of data from 27,805 pupils from 2,451 schools in 1988. It consists of
student, school, and transcript components, which present objective information
and subjective assessments for the five parent choice behavior issues.
Most of the variables for curricular
and extracurricular activities are from the school component of NELS.
Meanwhile, parental involvement is assessed using five variables – the fraction
of parents who discuss high school curricular choices with their children, who
visit school, who attend meetings, who attend parent-teacher conferences, and
the administrator’s assessment of how much parents are involved in decisions
about school policy.
To assess whether a school encourages
students to take a challenging curriculum, the proportion of students who took
the advanced placement scores is taken, while the sternness of the academic
environment is evaluated using six measures – an index of grade inflation in
mathematics, an index of grade inflation in English, number of hours of
homework assigned per week, number of standardized credits required for
graduation, administrator’s assessments of the degree to which students place a
priority on learning and are expected to do their homework.
The measurement for grade inflation in
mathematics is obtained by taking the difference of the percentile score on a
standardized mathematics test and the grade point average in mathematics. Grade
point averages are measured on a four-point scale. The percentile scores are
divided by 25 before subtracting so that they too will be on a four-point
scale. Student differences are then averaged within the school. One letter
grade’s worth of grade inflation is indicated by an increase of 1 in the
school’s index. The index of grade inflation in English is computed similarly.
To determine if a school has a
structured, disciplined environment, two objective measures are assessed – the
number of minutes a pupil spends in class daily and the action taken by the
school against a delinquent student – and four subjective measures the
administrator’s assessment of the degree to which the school has structured
classrooms, has a structured school day, does not tolerate deviation from
rules, and provides a flexible environment.
The weight that a school puts on sports
programs relative to academic programs is gauged using the administrator’s
assessment of the degree to which the school emphasizes sports and the ratio of
physical education to faculty in core subjects. The percentages of students who
join varsity teams, intramural sports, band, choirs, and orchestras are also
taken.
Descriptive statistics of the variables
mentioned above reveal that parent involvement has a large variance. The
percentages of students who take AP courses also vary extensively. And although
about half of schools have a regular mathematics track that is challenging,
great variation was also observed.
IV. Empirical Strategy
An intuitive strategy to identify the
impact of choice on school policies would be to compare choice and nonchoice
schools with students who are similar in terms of their measured aptitude and
demographics by using linear regression on a school policy measure and on a
variable that indicates whether the school is a choice school. However, this
strategy is troubled by a serious selection problem. Parents and children who
select choice schools are different from those who do not on the basis of both
observable and unobservable traits. As such, parents and students that are
expected to select choice schools might act differently even if they used
regular schools and the policy in choice schools will reflect both policy
decisions and different types of pupil.
Some researchers tried to eliminate the
selection problem by evaluating choice at the district level rather than on the
school level. A district is specified a choice district if it has one choice
school. The evaluation between choice and nonchoice districts can show how
policy is altered when schools are subject to more parental pressure because of
choice. This type of comparison is normally done using linear regression of a
school policy measure on variables that describe the demography of the school
and a variable that indicates whether the district is a choice district. This
strategy deals with the selection problem because a choice district must deal
with all parents and students in the district, not just those who actively
choose. However, one more problem remains: choice programs are usually
reactions to underlying conditions in the district. Comparisons between choice
and nonchoice districts cannot distinguish between the effects of having a
choice program from the effects of the circumstances that caused the program.
To produce unbiased estimates of the
effect of choice on school policy, a variation in the degree of choice that is
independent of the circumstances of the school and district must be accounted
for. Statewide programs are potential subjects for future research. However, it
disregards variation due to differences in school districting – an important
source of variation in the degree of school choice available in the United
States.
Herfindahl indexes are a
widely-accepted measure of the number and variety of school districts in a
metropolitan area. This measure is constructed by first getting the school
district’s share of total enrolment in the metropolitan area. Then these shares
are squared, summed within each area, and multiplied by -1. The index will be
equal to -1 if there is no choice at all and moves to zero as the number of
school districts increases and as enrolment is spread evenly across districts.
The lower the index, the less choice among districts there is in a metropolitan
area. Also, the difference between metropolitan area with and without choice is
approximately a one-unit change in the index.
The average metropolitan area in the
United States is about -0.17. This measure, however, is highly variable. Also,
parents are likely to concentrate in school districts that are good in
unobservable ways. This biases results toward finding metropolitan areas with
high enrolment rates. To reduce this bias, the researcher must focus on
determining if a metropolitan area is likely to be divided into many districts
and to ignore enrolment concentration that is caused by parents choosing more
successful districts. This is done by estimating the regressions by instrument
variables. Both Ordinary Least Squares (OLS) and instrumental variable (IV)
estimates are presented.
To differentiate between the effects of
choice and the effects of a homogenous student body, the measures of population
homogeneity within districts are controlled in the regression. Data from the
Public School Universe and the school district tabulation of the census are essential
to this. They allow for the measurement of within-district homogeneity gauges.
V. Results
A. The
Effect of Choice on Parental Involvement
Both OLS and IV estimates suggest that
choice increases parental involvement. An increase in choice causes parents to
visit the school more often, discuss the curriculum with their children, and
trigger administrators to raise parental involvement in policymaking. Also,
greater choice causes a higher percentage of parents to attend PTA meetings and
parent-teacher conferences. These results imply that parents believe that they
get more return from involvement when they have more choice. This is probably
because as suggested by the bargaining theory, administrators are more willing
to set policy that goes with parent preferences when the threat of exiting is
more likely.
B. The
Effect of Choice on the Curriculum
There is considerable evidence
suggesting that, consistent with survey findings, schools that are under more
pressure from parental choice expose their students to more intellectually
challenging study. This infers that if given the choice, schools would rather
give an easy curriculum because otherwise, school teachers and administrators
will bear much of the work. This result is also consistent with a previous
study, which discovered that students who come from schools that face more
competition are likely to have higher achievement test scores.
C. The
Effect of Choice on the Academic Environment
Schools that are in an environment
where parents have more choice allow more grade inflation. This suggests that
parents respond to incentives given by college admissions. This is under the
assumption that admission officers encounter difficulty in adjusting for grade
inflation. Or perhaps, employers and parents are misled by inflated grades.
Note, however, that grade inflation does not mute incentives to perform. Results
also show that schools are more likely to encourage students to develop good
habits of work and learning when they are subject to greater choice. It appears
that parents are capable of evaluating some school policies and of choosing
schools that offer policies that are consistent with their preferences.
D. The
Effect of Choice on a School’s Emphasis on Structure and Discipline
Consistent with the preference of
parents, results indicate that Tiebout choice compels schools to emphasize
discipline and give more structure. If left on their own, schools would rather
implement less structure and discipline. This could be because the school staff
will bear much of the cost associated with giving and maintaining more
discipline.
E. The
Effect of Choice on the Priority of Sports and Extracurricular Activities
There is no enough evidence to confirm
that more choice for parents will expand the priority given to sports and
extracurricular activities. Results do not indicate that choice suppresses the
said activities. However, it also does not support the conjecture stating that
choice would sacrifice academic programs to them.
VI. The Importance of Accounting for Selection and Endogenous
Programs
It was shown that when selection and
endogenous programs are not accounted for, results will be biased and difficult
to interpret. They will be unreliable in indicating what average parents seek
in a school. Comparison between choice and nonchoice schools and districts
verified this point.
Comparing choice and nonchoice schools will be subjected to
selection bias if parents and students who choose their schools differ in
unobservable ways from the rest of the population. Meanwhile, estimates that are generated from
comparing choice and nonchoice schools will be biased if intradistrict choice
programs are endogenous responses to district circumstances. As expected, all
results show inconsistent patterns and are not usable for rational
interpretation.
VII. Conclusions
Overall, results indicate that choice
would not weaken academic and disciplinary standards in the U.S. Also, what
parents say they want out of schools is what they choose given the opportunity
to do so. Schools that operate in metropolitan areas where parents can choose
easily among school districts tend to have more challenging curriculums,
stricter academic requirements, and more structured and disciplined
environments. Schools, on the other hand, do not focus much on sports and
extracurricular activities. Choice seems to make parents more involved in what
their local schools do.
On top of this, an interesting result
was observed. It appears that greater parental choice cause grade inflation.
This indicates that someone – college admission officers, employers, or parents
– is fooled by nominal grades. Even so, despite lower nominal standards, the
pressure of choice still causes schools to raise real standards. That is,
students still achieve higher scores on standardized tests.
The goals of parents for schools are
aligned with traditional ones. They want students to excel academically and
have good work habits and self-discipline. With this consequence, school
reforms that allow parents to challenge school policies like vouchers and
charter schools, will most likely prompt higher academic standards.
