Enrollment Projection Study UpdateCharles Kofron, Ph.D. LLC
August 19, 2019
OVERVIEW• Scope of Work• Findings• Data and Methods
– District geography– Birth record processing and results– District births and K enrollments and projections– Attendance area births and K enrollments and projections– Student record geocoding and processing
• Projection Method• Projection Results
– Total District resident enrollments and projections– Elementary District resident enrollments and projections– Middle School District resident enrollments and projections– High School District resident enrollments and projections
• Summary• Recommendations
SCOPE OF WORK• Obtain current (2019) geographic information system (GIS) base data
from the St. Louis County GIS Service Center• Obtain and geocode 2 years of student records (from September 30, 2018,
and 2019*) and build out class cohorts using District attendance areas – Overlay student locations on attendance area data and summarize residential
counts by attendance area, grade, and school year– 2019 student record data will be processed and added as an Addendum to this
report as these data become available (probably in October 2019)• Obtain, code to Kindergarten year of eligibility, geocode, and summarize
2 years of live birth data (from calendar years 2017 and 2018)– Overlay birth locations on attendance areas and summarize by Kindergarten
cohort year and attendance area– Birth data used to project in-District Kindergarten class sizes by attendance
areas • Develop K-12 cohort survival enrollment projections by attendance area
for a 5-year projection time period (2019-2024)– Enrollment projection model will include 5 series of school enrollment
projections based on residence as developed in benchmark study• Provide a summary report
FINDINGS
• Positive Enrollment Projection Profile Continues– Expect In-District enrollments to increase by 13% by 2024-
25• Elementary enrollments will continue to increase by 234 (5-Year
Average projection scenario) or more students by 2024 or 9% over the next 5 years
• Middle school enrollment will increase by 114 (Snapshot projection scenario) students or approximately 9% over the next 5 years
• High school enrollments will increase by 184 (Snapshot projection scenario) or 11% over the next 5 years
– Births hit a 14-year high for the 2020-21 Kindergarten cohort but have declined in the following 2 years• The District birth trend increased in Kindergarten cohort size
for the 2023-24 school year; however, birth projections for the remainder of the 2024-25 school year indicate smaller Kindergarten classes
DATA AND METHODS• Replicate Data Processing and Projection Methodology Developed in
Benchmark Study (2015)• Kirkwood R7 Base Data
– Student Records• Add Fall enrollments from September 30, 2018-19 to 2008-2017 base counts
– Geocode resident student records, overlay on attendance areas, and develop counts by grade and attendance area
– Exclude data outside of District» VICC, Normandy/Riverview Gardens, and other students attending from outside of
the District– Birth Records
• Add live birth addresses from 2017-2018 to 2004-2016 base counts– Assign births from 2017 and 2018 to complete 2022 and 2023 Kindergarten cohorts– Use remainder of 2018 births to project a full year of births for the 2024 Kindergarten cohort– Geocode live birth addresses, overlay on attendance areas, and develop counts for
Kindergarten cohort years
• Projection Method– Cohort Survival
• Births to Kindergarten cohorts by attendance area• K-12 resident student class cohorts by grade and attendance area
PROJECTION METHOD• Cohort Survival
– Assemble births and enrollments by cohort or class– Calculate ratios of students “surviving” to the next grade– Weighted ratio averaging
• Using the last 5 years of ratios by grade, average the 3 higher, mid, and lower ratios
– Averaging last 5 years of CSRs• 5YrAve series
– No averaging• Snapshot series
– Apply ratios to birth totals to generate Kindergarten projections– Apply grade-specific ratios to grade-specific enrollment counts to
generate projections for grades 1-12– For Kindergarten projections, use birth counts for future
Kindergarten classes to project enrollments

High Mid Low 5yrAve Snapshot
SUMMARY• Positive Enrollment Projection Profile Continues to 2024
– Mid, 5-Year Average, and Snapshot projection series converge, producing similar results• Convergence = Confidence
– Elementary projection trend lines begin to diverge in 2021• Snapshot projections show continued increase for 2023 but a leveling off in 2024• Mid and 5YrAve projections show possible downward trend in elementary enrollments in 2024
– Middle school enrollments will increase but at a slower rate• Mid and 5YrAve projection trend lines are indicating steady, increasing enrollments• Snapshot projections are showing increasing enrollments but fewer total students than the Mid and
5YrAve projections in 2024– High school enrollment projections are indicating steady enrollment increases
• Mid and 5YrAve projection scenarios are showing increases of 80 to 100 more students than the Snapshot projection series
– Births hit a 14-year high for the 2020-21 Kindergarten cohort, but fell back in later Kindergarten cohort years• Births declined in the 2021 and 2022 Kindergarten cohort years• Births increased from the 2022 to 2023 Kindergarte3n cohort years, but nowhere near the gain
shown between 2019 and 2020• 2024 Kindergarten cohort births based on extrapolation of 5-month trend are indicating a smaller
Kindergarten cohort and fewer enrollments– Expect In-District enrollments to increase by about 13% or 709 students
• Expect elementary enrollments to increase from 234 to 411 students by 2024• Middle school enrollments will increase from 114 to 207 students between 2018 and 2024• Expect high school enrollments to increase from 184 to 286 students between 2018 and 2024
SUMMARY• Expect Keysor total resident enrollments to increase by about 100
students between 2018 and 2023, but enrollments will fall back by about 40 students between 2023 and 2024– The Snapshot projection (based on the latest succeeding year enrollments) is
showing a much high gain in enrollments• North Glendale resident enrollments will continue to stay about the
same and increase by a class size between 2021 and 2023; however projections based on succeeding year enrollments show a sharper gain in enrollments between 2021 and 2024
• Notable enrollment increases are expected in Robinson between 2018 and 2020; enrollments after 2020 will stay about the same– However, the snapshot projection scenario is showing a decline in total enrollments
between 2018 and 2024• Like Robinson, Tillman enrollments are expected to increase between
2018 and 2021 and remain steady through 2024; however, the Snapshot projection scenario based on succeeding year enrollments is indicating a decline in total enrollments
• Westchester enrollments are expected to increase steadily over the next 5 years with total enrollments in 2024 around 585 students
SUMMARY• Nipher middle school enrollments will increase by 50
students in 2019 and will remain between 650 and 700 students through 2024– However, the Snapshot projection series is indicating
declining enrollments between 2019 and 2024 and this series is tracking closer to the Low projection scenario
• North middle school enrollments will start an upward climb in 2020 and continue to increase through 2024 when it is expected that enrollments totals will be between 788 and 800 students
• Kirkwood senior high school enrollments will continue to increase steadily with expected gains of between 184 and 286 students in 2024
RECOMMENDATIONS
• Keep resident student counts by attendance area current with fall (September 30) enrollments
• Keep resident birth data by attendance area current using data obtained through MoDHSS
• Evaluate projections with comparisons to actual enrollment counts (will do for 2019 enrollments)
• Incorporate District land use and improvements (housing data) using local data sources
• Incorporate independent demographic estimates and projections into the planning process
