REPORT OVERVIEW
01
About The City Studies Project
Cohort 1 Cohort 2
The City Studies project examines the performance of schools in select U.S. cities,
including Austin. We study the academic progress of students as the measure of school
performance.

CHARTER SCHOOLS
Public schools operated independently from the
traditional school district, with autonomy in adapting
school designs and held accountable for education
results.
Charter Management Organizations (CMOs)
Organizations holding the charter and overseeing the
operation of at least three charter schools.
Independent Charter Schools
Organizations holding the charter and overseeing the
operation of a single or two charter schools.
SELECTIVE MAGNET SCHOOLS
District-run schools with focused themes and
academically selective admission.
There are only two selective magnet schools with student
growth scores in Austin during the span of this study.; We
redact the results for this type due to the small number of the
schools.
OTHER DISTRICT-RUN SCHOOLS
Public schools not belonging to any of above two types.

Sectors of Schools
COMMUNITIES MAY HAVE UP TO THREE SECTORS OF SCHOOLS
Research Question and Analyses
IN THIS REPORT WE EXAMINE ACADEMIC PERFORMANCE IN
AUSTIN USING DATA FROM THE SCHOOL YEARS 2017-18
THROUGH 2018-19. THERE ARE THREE LEVELS OF ANALYSIS.
Overall performance in
Austin schools over one
growth period.
• The performance of Austin students
is benchmarked against the state
average performance, accounting for
student characteristics.
• The performance of charter school
students within Austin are then
compared to that of similar
traditional public school (district
school) students within Austin.
Performance for Austin
charter schools and the
other public schools in
Austin over one growth
period.
Performance in the 2018-
2019 school year by
school type, race,
poverty status, English
language learner (ELL)
status, special
education status and
gender.
WE MAKE TWO SETS
OF COMPARISONS.
01 02 03
Achievement scores capture what a student knows at a point
in time. They are influenced by students’ prior conditions in
addition to schools’ contributions.
Growth scores indicate how much progress a student makes
from one year to the next. Growth scores allow us to zero in
on the contributions of schools separately from other factors
that affect point-in-time scores.
ACHIEVEMENT VS. GROWTH
We analyze student growth in standard deviation units so
that the results can be assessed for statistical differences.
The full set of findings appear in the Appendix.
In the following graphs of findings, we transform growth
from standard deviation units into days of learning based on
a typical 180-day school year.
IN THIS STUDY WE MEASURE
ACADEMIC PERFORMANCE AS HOW
MUCH GROWTH STUDENTS MAKE FROM
ONE YEAR TO THE NEXT.

Acknowledgments
Texas Education Agency, Texas
Schools Project, and Texas Higher
Education Advisory Board provided
supports in the acquisition of student-
level data.
Disclaimer: The conclusions of this research do not necessarily
reflect the opinions or official position of the Texas Education
Agency, the Texas Higher Education Coordinating Board, the
Texas Workforce Commission or the State of Texas.
The KLE Foundation assisted
CREDO with verifying the list of
public schools in Austin.
Types of Charter Schools
• With more schools and students than a single charter
school, CMOs have some operational advantages in their
ability to spread administrative fixed costs, thus
providing the possibility of greater efficiency. In
addition, CMOs may be able to support additional
programs and more robust staffing.
• Whether CMOs lead to better student outcomes is a
matter of interest across the country.
OUR ANALYSES OF AUSTIN CHARTER
SCHOOLS INCLUDE A BREAKOUT OF
CMOS AND INDEPENDENT CHARTERS.
There are two types
of charter schools.
CHARTER MANAGEMENT ORGANIZATIONS (CMOS)
Organizations holding the charter and overseeing the
operation of at least three charter schools.
INDEPENDENT CHARTER SCHOOLS
Organization holding the charter and overseeing the
operation of a single charter school. It may run the school
directly or contract with an organization which provides
services to one or two charter schools.
Methods
The annual academic growth of students in Austin from 2017-18 to 2018-19,
overall and by sector, is benchmarked to the state average growth,
accounting for student characteristics.
We also explore how one-year growth of Austin students for the period ending
in Spring 2019 differs by school type, race, poverty status, English language
learner status, special education status, and gender.
Days of Learning
While these tools create precise and reliable answers,
they are presented in technical terms that are not
user-friendly to a general audience. To translate the
technical results into terms that are accessible to non-
technical audiences, CREDO developed Days of
Learning.
CREDO USES ADVANCED
TECHNOLOGY AND
SOPHISTICATED STATISTICAL
TOOLS TO MEASURE STUDENTS,
SCHOOLS AND THE EDUCATION
LANDSCAPE.
Think about the students in your state’s public schools. For many of their years
of schooling, they take achievement tests to measure what they know at the end of
the school year. We can identify the average score for each test each year.
Imagine a student who scores exactly at the average in one year, say 4th
grade, and then in the following year, scores exactly at the average again on the 5th-
grade test. The amount of year-to-year learning for that student show us what the
average learning is for all the students who took both tests.
We do that calculation for every grade the state tests: 4th to 5th, 5th to 6th,
and so on.
CREDO uses those annual measures of average learning to represent a typical
year of learning, and equates that to a typical 180-day school year. We say that the
student in our example has gained 180 days of learning.
If a student makes more progress than the average student, we take the
amount of extra achievement and translate it into 180-days of learning plus “X” extra
days. We are creating a measure of student learning as if the student went to school
for 180 days plus X days. The size of “X” depends on how much more the student
learns than the average student — if it’s a lot more, then “X” will be a large number,
and if it’s a small amount more, “X” will be a small number.
The same is true for students who do not learn as much as the average
student. Instead of adding to the 180-days-of-learning average, we subtract from
that base to reflect the smaller-than-average advances that those students realize. In
these cases, the difference leads to numbers such a “165 days of learning” or “152
days of learning”. Against the average standard of 180 days, these smaller days show
that students learned as if they had only attended school for 180 days minus X days
during the school year.

  • 4. About The City Studies Project Cohort 1 Cohort 2 The City Studies project examines the performance of schools in select U.S. cities, including Austin. We study the academic progress of students as the measure of school performance.
  • 5. O O C C C CHARTER SCHOOLS Public schools operated independently from the traditional school district, with autonomy in adapting school designs and held accountable for education results. Charter Management Organizations (CMOs) Organizations holding the charter and overseeing the operation of at least three charter schools. Independent Charter Schools Organizations holding the charter and overseeing the operation of a single or two charter schools. SELECTIVE MAGNET SCHOOLS District-run schools with focused themes and academically selective admission. There are only two selective magnet schools with student growth scores in Austin during the span of this study.; We redact the results for this type due to the small number of the schools. OTHER DISTRICT-RUN SCHOOLS Public schools not belonging to any of above two types. C Sectors of Schools COMMUNITIES MAY HAVE UP TO THREE SECTORS OF SCHOOLS
  • 6. Research Question and Analyses IN THIS REPORT WE EXAMINE ACADEMIC PERFORMANCE IN AUSTIN USING DATA FROM THE SCHOOL YEARS 2017-18 THROUGH 2018-19. THERE ARE THREE LEVELS OF ANALYSIS. Overall performance in Austin schools over one growth period. • The performance of Austin students is benchmarked against the state average performance, accounting for student characteristics. • The performance of charter school students within Austin are then compared to that of similar traditional public school (district school) students within Austin. Performance for Austin charter schools and the other public schools in Austin over one growth period. Performance in the 2018- 2019 school year by school type, race, poverty status, English language learner (ELL) status, special education status and gender. WE MAKE TWO SETS OF COMPARISONS. 01 02 03
  • 7. Achievement scores capture what a student knows at a point in time. They are influenced by students’ prior conditions in addition to schools’ contributions. Growth scores indicate how much progress a student makes from one year to the next. Growth scores allow us to zero in on the contributions of schools separately from other factors that affect point-in-time scores. ACHIEVEMENT VS. GROWTH We analyze student growth in standard deviation units so that the results can be assessed for statistical differences. The full set of findings appear in the Appendix. In the following graphs of findings, we transform growth from standard deviation units into days of learning based on a typical 180-day school year. IN THIS STUDY WE MEASURE ACADEMIC PERFORMANCE AS HOW MUCH GROWTH STUDENTS MAKE FROM ONE YEAR TO THE NEXT. Measure of Academic Performance

  • 29. Summary of Findings The summary of the findings from the analysis of Austin schools is presented here.
  • 31. Acknowledgments Texas Education Agency, Texas Schools Project, and Texas Higher Education Advisory Board provided supports in the acquisition of student- level data. Disclaimer: The conclusions of this research do not necessarily reflect the opinions or official position of the Texas Education Agency, the Texas Higher Education Coordinating Board, the Texas Workforce Commission or the State of Texas. The KLE Foundation assisted CREDO with verifying the list of public schools in Austin.
  • 32. Types of Charter Schools • With more schools and students than a single charter school, CMOs have some operational advantages in their ability to spread administrative fixed costs, thus providing the possibility of greater efficiency. In addition, CMOs may be able to support additional programs and more robust staffing. • Whether CMOs lead to better student outcomes is a matter of interest across the country. OUR ANALYSES OF AUSTIN CHARTER SCHOOLS INCLUDE A BREAKOUT OF CMOS AND INDEPENDENT CHARTERS. There are two types of charter schools. CHARTER MANAGEMENT ORGANIZATIONS (CMOS) Organizations holding the charter and overseeing the operation of at least three charter schools. INDEPENDENT CHARTER SCHOOLS Organization holding the charter and overseeing the operation of a single charter school. It may run the school directly or contract with an organization which provides services to one or two charter schools.
  • 33. Methods The annual academic growth of students in Austin from 2017-18 to 2018-19, overall and by sector, is benchmarked to the state average growth, accounting for student characteristics. We also explore how one-year growth of Austin students for the period ending in Spring 2019 differs by school type, race, poverty status, English language learner status, special education status, and gender.
  • 34. Days of Learning While these tools create precise and reliable answers, they are presented in technical terms that are not user-friendly to a general audience. To translate the technical results into terms that are accessible to non- technical audiences, CREDO developed Days of Learning. CREDO USES ADVANCED TECHNOLOGY AND SOPHISTICATED STATISTICAL TOOLS TO MEASURE STUDENTS, SCHOOLS AND THE EDUCATION LANDSCAPE. Think about the students in your state’s public schools. For many of their years of schooling, they take achievement tests to measure what they know at the end of the school year. We can identify the average score for each test each year. Imagine a student who scores exactly at the average in one year, say 4th grade, and then in the following year, scores exactly at the average again on the 5th- grade test. The amount of year-to-year learning for that student show us what the average learning is for all the students who took both tests. We do that calculation for every grade the state tests: 4th to 5th, 5th to 6th, and so on. CREDO uses those annual measures of average learning to represent a typical year of learning, and equates that to a typical 180-day school year. We say that the student in our example has gained 180 days of learning. If a student makes more progress than the average student, we take the amount of extra achievement and translate it into 180-days of learning plus “X” extra days. We are creating a measure of student learning as if the student went to school for 180 days plus X days. The size of “X” depends on how much more the student learns than the average student — if it’s a lot more, then “X” will be a large number, and if it’s a small amount more, “X” will be a small number. The same is true for students who do not learn as much as the average student. Instead of adding to the 180-days-of-learning average, we subtract from that base to reflect the smaller-than-average advances that those students realize. In these cases, the difference leads to numbers such a “165 days of learning” or “152 days of learning”. Against the average standard of 180 days, these smaller days show that students learned as if they had only attended school for 180 days minus X days during the school year. 01 02 03 04 05 06 3rd Grade 4th Grade = 180 days More than 180 days Less than 180 days Student A Student A
