The document provides information about calculating a yield factor to help school districts determine when expansions or new schools are needed based on population growth. It includes: 1) An example calculation of yield factor using enrollment increases and building permits over 4 years. 2) Directions to use yield factors and number of new homes to estimate the number of new students moving into a district. 3) A process for school engineers to analyze data, develop expansion plans based on identified needs, and present proposals to obtain funding. The document guides analyzing student enrollment data and housing growth to forecast needs and plan school expansions before overcrowding occurs. It emphasizes

1. Yield Factor

2. DeSoto is one of the most rapidly
growing school districts in Kansas!
• How do school districts
know when it is time for
a new school or an
addition to an existing
one before students are
overflowing into the
halls?

3. Vocabulary
•Demographics
•Growth
projections
•Yield factor
-Selected population used in
research.
-estimate of future population.
-increase in population based on
determined perimeter.

4. Yield Factor Formula
• The four-year enrollment change in a
district divided by the total number of new
home building permits during the same 4
year period.
YF = 4-yr student increase
# of permits

5. Yield Factor Example
For the years 2000-2004:
• LTMS, MTMS & MCMS’s enrollment went
up 154 students.
• The city of DeSoto, Lenexa, and Shawnee
issued 500 new home building permits.
Yield Factor = 154 = .308
500
Let’s practice!

6. Expansion on the Front!
• A new sub division is being built in the
Mathoroma school district. As one of
the civil engineers working for the
district you must estimate if and when
new schools or school expansions are
needed.

7. Estimating
Student Growth
• Calculate:
–Number of new homes built
multiplied by the yield factor.
Example: New homes = 300
Yield factor = .547
Estimated new students = 300 x .547
= 164.1
about 164 new students

8. Make your professional predictions!
1. Note the enrollment changes and the # of
building permits….
- Calculate the yield factors for each grade
level.
1. Use the yield factors and the # of new
home in 2007…
- Estimate number of new students.

9. Make your professional predictions!
• Look at the estimated number of new
students that you calculated.
• Find out how many more students can be
added to each school.
• Compare these two numbers and decide
what actions, if any, need to be propose to
the school board.

10. Brainstorm: What
determines a good education
for students?
• With your group make a list of the factors that
help provide students with a good education.
– Ex: Small class sizes
• One person be the recorder and write the list
down.

11. How do the other factors
affect the decisions for a
new school or school
addition?
• Individually, write down your ideas
about how the other factors would
affect the proposal you made for new
schools or school additions in the
Mathoroma school district.
– Use complete sentences
– Give reasons why and data to support
(not just your opinion).

12. Our List of Factors that
Contribute to a Good Education

13. Suggestions of factors that
contribute to a good education
• Longer passing periods
• Smaller class sizes
• A pod for all grades
• AC and heating
• Longer lunch
• Healthier lunch options
• More bathrooms
• Snacks
•More supplies
•Bigger lockers
•More sports &
extracurricular activities
•More/longer gym class
•More teachers per room

14. Priorities? Possibilities?
• Look at your list.
• Highlight what is a priority.
• Circle what is a possibility.

15. Vocabulary
• Bond Issue – a way to
provide upfront
money, later paid back
by increased taxes.
School bonds are to
pay for suggested
school costs. Citizens
vote to pass the bond
or not.

16. For your house value…
 Calculate the amount of property tax you are
currently paying per year.
 Rate: 1.473% of house value per year
Example: house value = $125,000
125,000 x .01473 = 1841.25
$1841.25 in property taxes each year

17. For your house value…
 Calculate the total amount of additional
property tax for one year if just Question 1
passes.
 Calculate the total amount of additional
property tax for one year if both pass.
 How would you vote on Question 1 and
Question 2 if you were a home owner?

22. Planning for Expansion
• Interpret what you see on the page.
• Why the page is needed in the plans.
• Apply the information to what you know and
have seen about the school building.
• Research one item (word, abbreviation,
concept…) that you do not understand online.
Ex: A one hour wall.
