School Ratings and Housing Factors in Austin
An Independent Study Report

Introduction
Under the direction of Dr. Brock Brown, Professor in the Texas State
University – San Marcos Geography Department and Dr. James LeSage,
Professor in the Texas State University – San Marcos Finance and Economics
Department, this research was conducted for the purpose of determining the
relationship between high school accountability ratings and housing factors
within the Austin MSA. Data was collected and organized into one of 62
groups based on location within the boundary zone of each public high
school building that graduates 12th graders in the Austin MSA.
Each high school building is issued an individual rating by the Texas
Education Agency, separate than that of the district in which it is located, so
this study will use the more precise, building-specific data, rather than the
broad district ratings. Housing factors such as median selling price, selling
price/ sq. foot, days on the market and school building’s percentage share of
total houses sold were examined. Annual school building accountability
ratings were collected from the Texas Education Agency and housing market
information was gathered from the Austin Board of REALTORS® (ABoR)
historical database.

Part One – Data Presentation
Annual school building accountability ratings were gathered for each of
the 62 high school buildings for each of the three years analyzed in this
study. The Texas Education Agency issues individual ratings to each building
separate from the rating issued to the district as a whole and those
individual ratings are the ones that this study looks at. The TEA ratings for
each building are based on student achievements on standardized tests,
building graduation rates, building attendance rates and various other
factors. Each building is then awarded a rating in one of the five following
categories, which are listed in descending order of achievement: Exemplary,
Recognized, Academically Acceptable, Academically Unacceptable, No Data /
Not Rated.
The Austin Board of REALTORS® maintains a historical database of
information pertaining to property sales over the past several years. Housing
factors can be cross-referenced by location within a particular school building
boundary and isolated to provide statistics on home sales within the
boundary of each building. This data can then be cross-referenced with date
and provide very specific data regarding sales statistics within a specific
timeframe and within a specific high school building boundary, as shown in
Figure 1.

The data for this study comes from three separate annual periods.
August 1st through July 31st was selected as the annual period because this
correlates to the time period that new TEA ratings are released each year.
The logic behind this is that TEA ratings are released on the last day of July
each year and home buyer and sellers would use this information in making
buying and selling decisions from August 1st until the next year’s rating is
released on the last day of July. The most up to date data was used in this
study, representing three years of available data, released in July of 2008,
2009 and 2010. The three year periods are as follows:
2008 - 09: August 1st, 2008 – July 3st, 2009 (TEA Rating issued in July
2008)
2009 - 10: August 1st, 2009 – July 31st, 2010 (TEA Rating issued in
July 2009)
2010 - 11: August 1st, 2010 – July 31st, 2011 (TEA Rating issued in
July 2010)
A. Building Performance and Location
The raw data for 2008 – 09 is presented in Table 1. Only one school,
Westlake High School in Eanes Independent School District, achieved the
highest rating of “Exemplary” in 2008 - 09. Nine schools achieved a rating of
5 | P a g e C h r i s t i J . M o n c r i e f Y i n
“Recognized” and forty schools achieved a rating of “Acceptable”. The large
number of “Academically Unacceptable” ratings is disturbing as this means
that these high schools did not sufficiently teach their students the required
information to pass the basic standardized test, did not graduate an ample
amount of their students and did not even see an acceptable amount of
attendance by their students during this year. Seven high schools in the
Austin MSA fit into this category during 2008 - 09, which is a full 11% of the
high schools. There were also five schools that received a “No Data” rating
during 2008 - 09 which means that the TEA did not publish a rating for this
building. The likely reason for this is that the building is new and has not
been in existence long enough to meet the state requirements to be
awarded a rating.

Figure 2 illustrates the spatial distribution of high school accountability
ratings during 2008 - 09. Take note that only one high school building
received the highest rating of “Exemplary”.
Figure 2: 2008 - 09 High School TEA Ratings in the Austin MSA

Data for 2009 - 10 is presented in Table 2. Four schools joined
Westlake High School this year in achieving the highest rating of
“Exemplary” for a total of five schools to earn this honor. Fifteen schools
achieved a rating of “Recognized” and thirty-three schools achieved a rating
of “Acceptable”. The number of “Academically Unacceptable” ratings fell
slightly this year, with a total of only five buildings receiving this rating. It is
noteworthy that of the seven buildings receiving the “Academically
Unacceptable” rating during 2008 - 09, all but two, Reagan High School in
Austin ISD and Manor High School in Manor ISD, improved their standing for
this year’s ratings. The other three schools in this category this year are
buildings that fell from a higher rating and are new to this group. Three
buildings received a “No Data” rating during 2009 - 10.

11 | P a g e C h r i s t i J . M o n c r i e f Y i n
Data for 2010 - 11 is presented in Table 3. Many buildings have
achieved the highest rating of “Exemplary” this year, seven in all, more than
any of the other study years. Twenty-four schools achieved a rating of
“Recognized” and twenty-eight schools achieved a rating of “Acceptable”.
The number of “Academically Unacceptable” ratings fell to one this year,
with Eastside Memorial High School in Austin ISD being the sole building that
could not improve its standing. Two buildings received a “No Data” rating
during the final year of study.

B. Descriptive Statistics for Housing Factors
Summary statistics for all three years will provide a baseline for
analyzing the data in the growth regressions for the second part of this
report. The means, medians, standard deviations, minimums and maximums
are provided for all of the housing factor variables taken into account in this
study and shown individually for each of the three years being analyzed. The
following tables provide summary statistics for the days on the market, units
sold, median number of bedrooms, median number of bathrooms, sales
price in thousands and building ratings. In order to summarize the data
numerically, each TEA rating was assigned a number, as follows:
Exemplary: 4
Recognized: 3
Academically Acceptable: 2
Academically Unacceptable: 1
No Data: 0
The summary statistics for 2008 - 09 are presented in Table 4. Note
that the mean exceeds the median for the variables of days on market, units
sold and price in thousands indicating a right-skewed distribution of these
variables. The beds, baths and building ratings variables have means and
medians that are almost identical in this year indicating symmetry in those
housing factor variables.

Table 4: 2008 - 09 Summary Statistics
Table 5 presents summary statistics for 2009 - 10. In a similar case as
2008 - 09, the means are larger than the medians for the days on market,
units sold and price in thousands variables indicating a right-skewed
distribution. The building ratings this year have a mean that is more than
10% larger than the median as well, demonstrating a right skew in this
variable. The beds and baths are once again showing symmetry.

16 | P a g e C h r i s t i J . M o n c r i e f Y i n
Table 6 presents summary statistics for 2010 - 11. As in the first two
years there is a right-skew in the days on the market, units sold and price in
thousands variables. And in a story similar to 2008 - 09, the other three
variables, beds, baths and building ratings, depict symmetry. Also note that
the standard deviation for the price in thousands variable is much farther
away from zero in 2010 - 11 than it is in 2008 - 09 or 2009 - 10. This larger
standard deviation indicates a wider spread in the distribution of this
variable across the 62 high school building boundaries reflecting a greater
inequality than in the previous two years. This means that there are
significant numbers of properties selling in the higher price brackets and
significant numbers of properties selling in the lower price brackets but less
properties selling in the mid-range price brackets.

There is one more noteworthy relationship which is consistent among
all three years of collected data. The schools with the largest quantity of
housing units sold per year are not the schools which are rated the highest.
In fact, the majority of schools with large quantities of housing units sold are
rated at merely “Academically Acceptable”. Figures 8, 9 and 10 illustrate the
top ten schools for each year with the largest quantity of housing units sold.

C. Relationship between Housing Factors
A correlation coefficient is used to summarize the strength of the linear
association between the variables. If the variables go up and down together,
the correlation coefficient will be positive. If the variables go up and down in
opposition, the correlation coefficient will be negative. Keep in mind however
that correlation is not causation. It would be easy to misinterpret the
correlation coefficient tables and naively arrive at a false conclusion that
building ratings have an impact on housing factors. Part two of this study
will analyze in detail the connection between these factors to determine
whether or not there may be a causal relationship.
Table 7 presents correlation coefficients for 2008 - 09. It is clear by
the data in the building ratings column that there is a positive relationship
between building ratings and the other housing factor variables, especially
the median price.
Variables price/sf days on market median price building ratings
price/sf 1.0000 -0.0241 0.7887 0.2631

Table 7: 2008 - 09 Correlation Coefficients
22 | P a g e C h r i s t i J . M o n c r i e f Y i n
Correlation coefficients for 2009 - 10 are exhibited in Table 8. Positive
correlations between building ratings and the other variables are also
present in this year, although significantly less than in 2008 – 09, perhaps
due to the unique national housing market trends during this time period.

Table 8: 2009 - 10 Correlation Coefficients
Table 9 presents correlation coefficients for 2010 - 11. Once again the
building ratings column displays positive relationships between building
ratings and all other housing factor variables.

23 | P a g e C h r i s t i J . M o n c r i e f Y i n
In these correlations, median price and price per square foot are
strongly related suggesting that either one is a good measure of general
price trends. Otherwise, the housing factors are not strongly interrelated and
are suitable for robust statistical analysis.
24 | P a g e C h r i s t i J . M o n c r i e f Y i n
Part Two – Data Analysis
Spatial dependence implies that observations (sales price of homes,
for example) depend on other observations (building ratings of the local high
school, for example) either at that location or at a location in relative
proximity to the location of the original observation.
Growth regressions are an important statistical analysis tool as they
can determine causal relationships between observations while taking into
account outside variables and explain the interdependent relationship of one
observation to another. Nothing is independent of anything else but
sometimes it’s difficult to understand the connectivity of relationships
without a close analysis. In this section multiple regression models will be
used to test the role of school quality (and other control variables) verses
three key housing indicators:
1) Total Price
2) Days on the Market
3) Price per Square Foot
A. Total Price
The first three growth regressions presented use “Price in Thousands”
as a dependent variable. These three regressions examine how building
25 | P a g e C h r i s t i J . M o n c r i e f Y i n
ratings affect the selling price of homes within their own boundary as well as
homes within the neighboring boundaries. “Neighboring boundaries” refer to
the six geographically closest high school zones to the zone of the original
observation. The impact that is shown in the neighboring district is the total
impact among all of the districts; therefore it must be divided by six to
determine the impact on one individual neighboring district.
Figure 11 shows the growth regression for 2008 - 09 using “Price in
Thousands” as the dependent variable. The R-squared value of the model
indicates a low value for prediction overall, but the building ratings are
reporting a substantial influence on median price which is statistically
significant at the 70% level. What this means is that for each single increase
in building rating (i.e. a jump from Academically Acceptable to Recognized)
the median sales prices of homes within that high school boundary increases
by more than $4,000.00. The neighboring median price is also reporting an
increase of $500.00 but is not statistically significant. Given the model
results and controlling for other variables, this model concludes to a certain
degree that an increase in building ratings causes an increase in median
sales price for homes located within the boundary of that high school.

increase in building ratings have a positive causal relationship with median
sales price of homes located within that building boundary. Their findings are
directional and consistent although not necessarily very convincing due to
some of the low statistical values.

B. Days on the Market
The second three growth regressions presented use “Days on the
Market” as a dependent variable. These three regressions examine how
building ratings affect the amount of time it takes to sell a home after it has
been officially listed for sale.
Figure 14 shows the growth regression for 2008 - 09 using “Days on
the Market” as the dependent variable. The R-squared value of the model is
very low. The building ratings are reporting an influence on days on the
market which is statistically significant at the 70% level. What this means is
that for each single increase in building rating the median days on the
market of homes within that high school boundary increases by 4.5 days.
This could indicate that homes located within those higher performing school
boundaries are holding out for a more favorable sales price rather than
accepting the first offer presented to them. Given the model results and
controlling for other variables, this model supports that an increase in
building ratings causes an increase in days on the market for homes located
within the boundary of that high school.

increase in building rating the hold time of homes within that high school
boundary increases by 6.7 days. Given the model results and controlling for
other variables, this model concludes that an increase in building ratings

causes an increase in days on the market for homes located within the

33 | P a g e C h r i s t i J . M o n c r i e f Y i n
building rating the median days on the market of homes within that high

building ratings causes an increase in days on the market for homes located
within the boundary of that high school.

The second three growth regressions do not have the advantage of high
statistical significance; however, the evidence that they do provide
34 | P a g e C h r i s t i J . M o n c r i e f Y i n
concludes that an increase in building ratings has a positive causal
relationship with median days on the market located within that building
boundary. Their findings are directional and consistent although not
necessarily very convincing due to some of the low statistical values.
C. Price per Square Foot
The final three growth regressions presented use “Price per Square
Foot” as a dependent variable. These three regressions examine how
building ratings affect the selling price per square foot of homes within their
own boundary as well as homes within the neighboring boundaries.
Figure 17 shows the growth regression for 2008 - 09 using “Price per
Square Foot” as the dependent variable. The R-squared value of the model is
moderate. The building ratings are reporting a positive influence on median
price per square foot but it is not statistically significant. The neighboring
median price per square foot is reporting a positive increase of $2.00/sf
($12.00/sf total, divided among six neighbors) and is statistically significant
at the 85% level. This means that for every single increase in building
ratings, neighboring values increase by $2.00/sf. Given the model results
and controlling for other variables, this model concludes to a certain degree
that an increase in building ratings has a relationship with median sales price
per square foot in neighboring homes.

values indicating a strong level of prediction but unfortunately they were not
supported with results that were statistically significant. All three models did
indicate that an increase in test scores had positive impact on median price

statistical significance.

Conclusion
After controlling for the various housing factors associated with the
housing market in conjunction with building ratings, the regression model
results point toward the following housing market dynamics:
School performance has a consistent and positive association with
overall housing price, suggesting that consumers pay a premium to
purchase houses within the boundary zone of high-performing high
schools;
School performance has a consistent and implicitly negative
association with the number of days on market – that is, houses within
the boundary zones of high-performing schools tend to be on sale
longer than houses with the boundary zones of lower-performing
schools – suggesting that homeowners within the boundary zone of
high-performing high schools are aware of their favorable position and
likely reject lowball offers, holding out for an offer that is more
favorable; and
School performance has a consistent and positive association with
price per square foot, suggesting not only that consumers pay a
premium to purchase houses within the boundary zone of high-
performing schools but that consumers pay a housing premium for
39 | P a g e C h r i s t i J . M o n c r i e f Y i n
school performance on houses of all sizes from small bungalows in old
neighborhoods to McMansions in new subdivisions.
In terms of overall conclusions from the statistical analysis, this initial
research indicates that school quality plays in important role in pricing the
real estate market and only a moderate role in the length of time it takes to
sell real estate. Given these conclusions, it seems clear that real estate
professionals can capture value in their housing transactions by promoting
school quality as a fundamental attribute of their housing listings and school
districts – even at the building level – can build value in the local housing
stock by maintaining and improving school quality measures.
As an initial exploratory project, this study provided some interesting
results and potentially opened the door to further research in a similar
direction. Even though the results shown did not have the benefit of
consistently high probability, they certainly were not random and did not
point in the direction of rejecting an impact. With different data and the use
of additional models future research may be able to conclude positive causal
relationships between school performance and housing market factors with a
high degree of statistical accuracy.
