Using School Level Achievement Data in
Determining Core Education Costs:
The Impact on Perceptions and Policymaking
David L. Silvernail, University of Southern Main
Introduction
What constitutes an adequate education? And what should this cost? Several states are
exploring these questions as they attempt to revise their school funding formulas. Some
are doing so in response to court orders that require them to eliminate current funding
inequities (e.g., New Jersey, Ohio, Wyoming), while others are trying to introduce more
equity and accountability into their school funding formulas (e.g., Illinois, Minnesota,
Mississippi, Oregon). Maine is doing so in response to the desire on the part of
policymakers to change Maine's school funding from an expenditure-driven formula to a
results-driven formula. This paper will describe Maine's efforts to date and the impact of
this work on perceptions and policymaking.
Background
The purpose of our contribution is to explore the effect of ignoring
one or more levels of variation in hierarchical regression analysis. In
a first analysis four hierarchical levels will be considered: the individual
pupil, the class group, the teacher and the school. We will investigate
the impact of ignoring the highest level (the school level), the highest
two levels (the school and the teacher level) and ignoring one or two intermediate
levels (the teacher and/or class level) on the attribution of the variance
to the levels taken into consideration .
Unlike many states in which the state constitution requires the state to provide a
thorough and efficient education for all students, Maine's constitution merely states that
"...the legislature are authorized, and it shall be their duty to require the several
towns to make suitable provision, at their own expense (emphasis added), for the
support and maintenance of public schools...". However, since the early 1830's, the
state of Maine has played an ever increasing role in the financial support of schools by
providing state tax money to the towns in support of education. And until recently,
Maine's formula has been an expenditure-driven one. Beginning in 1995 Maine adopted a
foundation program (except for transportation, special education , debt service, and
vocational education) designed to ensure that the state paid for at least 57% of education
costs. However, this funding law has come under criticism for three major reasons: (1) it
allows inequities to continue because of disparities in the capacity of different
communities to raise substantially different amounts of local school aid; (2) it permits
the state in times of limited resources to reduce its share of costs and thereby increase
local costs; and (3) it provides little accountability for how the funds are spent at the
local level.
From 1995-1997, the Maine Legislature took two key steps to change the way schools are
to be funded and held accountable. First, the legislature passed the Learning Results, a
set of learning standards in eight disciplines that schools must ensure that all students
achieve before they graduate from high school. Second, the legislature directed the State
Board of Education to develop a method of funding the programs and services necessary for
students to achieve the statewide learning standards. More specifically, Maine Public Law
1997, Chapter 24 charges the State Board of Education with the development of:
...an implementation plan for funding essential programs and essential services. The
plan must be based on the criteria for student learning developed by the Task Force on
Learning Results and established in Public Law 995, Chapter 649 and in rules adopted by
the Board and the Department of Education. The plan must include establishment of a system
to measure and ensure that schools are held accountable for student learning results.
Thus, the state board was charged with identifying the necessary inputs (programs and
services) required to produce the desired outputs (high student achievement) and to
develop a plan for holding schools accountable for student achievement. From the
perspective of policymakers (and business leaders), this charge seems very rational,
reasonable, appropriate and appealing. But as researchers and educators know all too well,
the devil is in the details. Some of these details and the approach taken in addressing
them are described in the next section of this paper. A subsequent section discusses the
impact of this approach on perceptions and policymaking.
The Maine Strategy
In response to the legislation, the state board in late spring 1997 established the
Essential Programs and Services (EPS) Committee and contracted with the Maine Education
Policy Research Institute (MEPRI) for research and technical assistance in determining the
cost of a Maine core education. The committee consisted of members representing various
stakeholder groups (e.g., teachers, administrators, school committees, State Board of
Education, Department of Education, and businesses). The research institute is a
non-partisan institute jointly funded by the state legislature and the Maine university
system, and charged by law with tracking K-12 developments and reform in Maine and with
conducting targeted research at the request of the legislature. The University of Southern
Maine office of the research institute has been working with the EPS Committee in
developing the Maine core education model since summer 1997.
The first step the committee faced in developing the Maine EPS model was defining what
constituted an essential program or service. After considerable deliberation, the
committee concluded that their work should be guided by one fundamental premise: The
purpose for developing a Maine EPS model is to ensure that all schools have the necessary
and essential programs and services so that all students have equitable educational
opportunities to achieve the Learning Results. Based on this premise, the
committee has developed a working definition of essential programs and services, a
definition that will be refined as work on the EPS model continues throughout this year.
This working definition is as follows:
Essential Programsare those programs and courses schools need to offer all
students, including special education and applied technology students, so that students
may meet the Learning Results standards in the eight Learning Results
program areas of:
- Career Preparation
- English Language Arts
- Health and Physical Education
- Mathematics
- Modern and Classical Languages
- Science and Technology
- Social Studies
- Visual and Performing Arts
Essential Services are those services which are necessary to ensure that each
Maine student is offered an equal opportunity to achieve standards within the essential
programs described above. These include:
- school unit personnel
- guidance services
- library services
- health services
- administrative services
- early childhood services
- social and family services
- special education services
- Limited English Proficiency (LEP services)
- disadvantaged youth services
- co-curricular student activities
- applied technology
- professional development
- student assessment
- equipment and supplies
- technology resources
- facilities
- transportation
- debt services
- others (to be determined)
Having established this purpose and these definitions, the committee came face to face
with several "devil in the detail" questions: (1) What standards of achievement
constitute sufficient achievement (how good is good)? (2) What level of each of these
programs and services is necessary and what should these cost? and (3) How do we know that
certain levels of programs and services will bring about the desired achievement levels?
Early reviews of what other states are doing in defining core education also led the
committee to one inescapable conclusion: no magic bullet exists. Maine would be
charting new waters in developing a results-driven model for funding its K-12 education, a
model that tied essential inputs to explicit outputs (student achievement).
After reviewing the literature on the education production model, the committee still
found some merit in exploring the connection between inputs and outputs in Maine schools.
That is to say, the committee reviewed the research conducted by Hanusheck (1996, 1997),
Hedges, Laine & Greenwald (1994) and others and recognized that the production model
findings are, at best, mixed. However, they did conclude that some of the most recent
research held promise. Thus, recognizing the central need to provide convincing arguments
for the way in which the committee would ultimately define essential program and services
and their costs in Maine, the committee concluded it was important to examine empirical
evidence from Maine schools. Accordingly, the committee requested that the research
institute conduct a study of Maine performance and the relationships, if any, between
performance and school characteristics.
High and Low Performing Maine Schools
The first step in exploring the Maine evidence entailed defining student performance
and a standard of student performance to use in examining Maine schools. The Maine
legislation establishing the statewide learning standards also mandated that the statewide
achievement test, the Maine Educational Assessments (MEA), be used to assess achievement
of the learning standards. The MEA is in the process of being revised to measure the eight
disciplines in the Learning Results, and the first testing is scheduled for 1999. Thus, it
will be several years before the state will have adequate, reliable and defensible
evidence on student achievement of the Learning Results. At present, the existing MEA
provides the only statewide data on student performance. Because the current MEA is the
only available data on performance, and because the current MEA does assess content
similar to that found in the new Learning Results, MEA data for the last three years was
used as a surrogate for future Learning Results performance.
The MEA measures 4th, 8th, and 11th grade student
achievement in six core areas: reading, writing, mathematics, science, social studies, and
arts and humanities. All of these areas are included to varying degrees in the new
statewide learning standards, but the current MEA will still need substantial realignment
for use in the future. At present MEA achievement is reported in six norm-referenced scale
scores and three criterion based proficiency level scores. Student level scale scores and
proficiency levels are reported for reading, writing and mathematics.
Three criteria were selected for defining a high or low performing Maine school. These
were the following:
- A school level composite scale score average of one-half standard deviation above or
below the state average.
- 75% or more (or less) of the students in the school scoring at the Basic or above
proficiency levels in reading, writing and mathematics.
- A school level composite scale score average 0.50 residual z-score above the predicted
school score.
To determine the first criteria, the six subtest scores over the last three years were
averaged. The average could range from 100-400 points with a standard deviation of 50
points. In the case of the second criteria, student performance in reading, writing, and
mathematics is also reported based on four criterion-referenced proficiency levels:
Novice, Basic, Advanced and Distinguished. The average percent of students reaching Basic
or above in the three content areas for the last three years was used in identifying
schools.
Determining the third criteria, the value-added criteria, was more complex. Based on
the work of Phillips and Adcock (1996) and Hofmann (1997), multiple regression was used to
examine the relationship between school level school scale performance (Criteria A) and
six community and school demographic variables. These variables were (1) median household
income; (2) percent below poverty level; (3) percent college degree; (4) percent in
professional position; (5) percent free or reduced lunch students in the school; and (6)
the midpoint of the school MEA comparison score band. The four community variables were
from the 1990 census. The free and reduced lunch percentages were provided by the Maine
Department of Education, and the comparison band information was provided by the private
testing agency responsible for developing and administering the MEA. Three demographic
factors are used by the agency in calculating school comparison score bands: (1) percent
free and reduced lunch; (2) percent of parents in white collar positions; and
(3) presence of computer/encyclopedia in home (elementary level) or highest degree level
achieved by one parent (middle and high school level). Table 1 reports the simple
correlation matrix for the six demographic variables and 11th grade school
level MEA performance. The information for the 4th and 8th grades
appears in Appendix A.

Based on this evidence, a stepwise multiple regression analysis was
conducted for each of the three grade levels (4th, 8th and 11th).
This analysis yielded two variables in the case of 4th grade (comparison score
band midpoint and percent poverty), and only one variable in the 8th and 11th
grade cases (comparison score band midpoint). These findings were expected given that the
comparison band score is calculated for parents only and does not include
non-parent community members (i.e., census data). The resulting R2 were .26,
.42 and .52 for the 4th , 8th and 11th grades
respectively. Based on this analysis, actual and predicted scores were generated for each
school in Maine, and the three criteria described earlier were used in identifying high
and low performing schools. This procedure resulted in the identification of 133 high
performing and 120 low performing schools. The breakdown by school level appears in Table
2. Data from these sets of schools were examined using analysis of variance procedures to
determine if significant differences were present between the schools on a variety of
input and resource variables. Variables examined in this analysis were those found in
other research studies, and variables that are being used by the Maine research institute
in developing a statewide indicator system.

Table 3 reports the findings from these analyses. This empirical information, along
with evidence collected from other states and task forces which are attempting to develop
core education models, is being used by the committee in developing the Maine model.
The committee has chosen to use prototypical schools (like New Jersey and Wyoming) as a
means for describing the Maine model and components. Examples of three prototypical
schools, and the work to date, appear in Appendix B. Work on the model is far from being
completed and will continue throughout this calendar year and into the next legislative
session.
Some of the additional tasks the committee will need to complete
include: (1) developing an accountability system including consideration of rewards and
sanctions; (2) determining the local and state shares of funding the EPS model; and (3)
determining what portion of the funds distributed will be as block and/or targeted grants.

Impact on Perceptions and Policymaking
Considerable work is still to be completed on the Maine model, and undoubtedly the
model will undergo many changes as a result of further discussion of the committee, public
hearings and legislative review. Still the impact of using school level achievement data
in building the Maine model is already evident in perceptions and policymaking.
First, and foremost, the empirical data has helped inform committee discussions and
decisions. One example is the evidence on teacher-student ratios. The assumption held by
most educators, and many parents, is that class size is a critical variable in
achievement. Nationally the evidence is mixed, but the data from Maine schools indicated
that teacher-student ratios were not a distinguishing variable in high and low performing
schools. That is to say, with the one exception of schools which housed only part or all
of grades 5-8, no significant differences were found for teacher- student ratios in high
and low performing schools. Subsequent analysis of these middle schools indicated the
differences found between the high and low performing schools were related to differences
in school size. The committee has used this finding in establishing ratios in the EPS
model.
Another example of the impact of the empirical evidence in the model building process
is in the area of teacher educational background. The evidence from the Maine schools
indicated that a higher percentage of teachers in high performing schools held masters
degrees in comparison to their colleagues in low performing schools. The committee has
recognized that degree attainment may be a powerful marker in itself, but also a marker
for a broader indicator of professional development. Thus, the committee is exploring ways
to build funding into the Maine EPS model for both further formal education (i.e., degree
programs) and professional development.
A second impact of the work to date on the EPS model is a key change in perceptions
held by many educators and policymakers throughout the state. Folk wisdom is that high
achieving schools are located in rich, high SES communities. In fact, the lack of these
community resources is often used as a justification for low performance - both on the
part of educators and legislators alike. The evidence from this study of Maine schools
suggests this is not always the case. The chart on the next page identifies the high (+)
and low (-) performing high schools by county. This chart (and a similar one for
elementary schools) has served as an eye opener and a springboard for many lively
discussions throughout the state. Individuals are realizing that some schools across the
state, from both rich and poor communities, are being successful in helping a majority of
their students achieve a statewide standard of performance. They are realizing that what
goes on inside the school can make a difference.
A third impact has been in the area of information development. Like most states, much
of the education data collected in Maine is of a financial nature and used for regulatory
and compliance purposes only. Fortunately, Maine has collected some recent school resource
survey data, but still the state is data poor for purposes of policy research. Much of the
data is incomplete, unverified, and at the district level. This study by the EPS Committee
has significantly increased the awareness on the part of policymakers that if they intend
to make more data-informed decisions, and to hold schools accountable for their use of
resources and results, more precise information is needed from schools and school systems.
Accordingly, policymakers have instituted a review of all educational data collected by
the state in anticipation of developing a new data collection system, one which will
provide information useful in an accountability system and in future policy research
studies.
Fourth, this study is having a positive impact on the future of policy research
development in the state. The research described in this paper is less detailed,
comprehensive and rigorous than one would expect in an in-depth study of the production
model. Nevertheless, it has served as a good example of how research may inform the
policymaking process. Consequently, in the case of Maine, the research has created a move
for improving the quality and level of data collected in the state. In addition, the study
of high and low performing schools and the use of this information in developing new
statewide policy such as the EPS model has created a renewed (or created a new) interest
and appreciation on the part of the Education Committee of the legislature for the value
and usefulness of policy research. As a result, the committee is turning more and more to
the research institute for information and analysis, and has recommended doubling the
institute budget this year (as an emergency measure).
Summary
Using school level achievement data as a strategy in defining a core
education is having a substantial impact on perceptions and policymaking in Maine. The
data and its use in exploring the empirical evidence about Maine schools has proved useful
to the committee charged with defining the essential programs and services that schools
should have available to them in providing equity of educational opportunities for all
students. The committee used the study findings to inform and guide their deliberations.
Additionally, the study has proved beneficial in other areas. It has been useful in
calling into question Maine folk wisdom about the power of community factors in setting
student achievement and the potential power of effective schools in overcoming these
community factors. The study has also served as a catalyst for improving the education
data collection system in Maine and for improving both the stature and funding of the
state education policy research institute. Only time will tell if the findings from this
analysis have a lasting impact on how Maine defines and funds a core education, but the
prospects are good that the analysis will improve Maine education policy development in
the future.
