SUBJECT: PAUSD Enrollment Projections K-12
STRATEGIC PLAN INITIATIVEBudget Trends and Infrastructure
BACKGROUNDOn March 8, 2011, the Board of Education conducted a study session to review enrollment andfacilities planning for the elementary schools. This session included an overview of district valuesand guidelines, enrollment data and projections, district demographics, available funding and abrief overview of district facilities and opportunities to accommodate future growth. A subsequentstudy session was held on June 7, 2011.
During the June study session, four recommendations from staff were discussed with the Board:
1. Suspend commitments of directed funds on elementary projects that do not increasecapacity.
2. Give three year termination notice to the Garland tenant in June.3. Direct staff to identify next sites for increased elementary capacity.4. Direct staff to prepare an annual cyclical process that creates a calendar for (1) review of
enrollment, (2) updating projections of future enrollment, (3) discussion of capital budgets,and (4) direction regarding the expenditure of bond funds to create capacity to addresselementary enrollment challenges.
Regarding these recommendations, the following has taken place.
1. A budget transfer of elementary school bond funds into the Elementary School Reservewas made on October 11, 2011. The reserve now stands on $33.3 million. This is inaddition to the $21.9 million designated for Garland improvements.
2. On June 13, 2011, the Board authorized the termination of the Garland lease.3. The timeline below provides an orderly process for identifying sites.4. The following timeline was reviewed for the site identification.

TIMELINE
The following timeline was presented to the Board on June 7, 2011.
October, 2011 Review of current enrollment (completed at Sept. 28, 2011 Board meeting)
December, 2011 Enrollment Projections for 2012-2013 and following years based on Octoberenrollment information (the projections are dated December 26, 2011 and arepresented at this meeting.)
February, 2012 Discussion of funds available in capital budgets (to come)April, 2012 Direction of Bond funds to increase elementary school capacity (to come)
Note: On November 1, 2011, the District purchased the property located at 525 San Antonio Road.
PROPOSED ASSUMPTIONS AND VALUES
The following list of assumptions and values was also reviewed at the meeting of June 7, 2011.
This conversation about enrollment growth requires a set of planning assumptions and planningvalues.
Planning Assumptions: (changes shown in i talics)
1. Forty more classrooms will satisfy growth needs for the next five to eight years.2. Kindergarten enrollment is the most reliable predictor of future K-12 enrollment.3. We have $75 million to meet elementary facility needs in the next 8 years. This amount is
now $55.3 million due to: the purchase of 525 San Antonio Road, the approval of theDuveneck schematic design and budget, and a more minor augmentation to theFairmeadow budget at bid award.
4. Growth trends and location flexibility of district programs will guide planning5. More capacity is needed where the ratio of student residents to existing neighborhood
school classrooms is highest6. 95% of current students live in housing built before 20007. Extra classrooms provide important flexibility8. Empty seats are necessary to minimize overflow.
Elementary Facilities Planning Values (changes made at the June 7, 2011 Board meetingshown in italics):
1. Neighborhoods matter: provide routine access to neighborhood schools2. School size matters: keep schools at or below 4.5 strands3. Commutes matter: use boundaries to minimize neighborhood school student travel across
busy streets such as the El Camino Real and the Oregon Expressway.4. Class size matters: maintain 22:1 for grades K-3 and 24:1 for grades 4-55. Peer Streaming matters: group neighborhood classmates together for middle and high
school.6. Special Education matters: ensure school stability and appropriate compliance7. Money matters: get a good return on bond investments8. Flexibility matters: plan a permanent extra classroom at all sites

9. Parity matters: plan comparable facilities, support staff space, play areas, andventilation/classroom comfort.
10.Learning matters: minimize disruption to school and classroom operations11.Contingencies matter: keep overflowed students within cluster when possible12.Diversity matters: consider the benefits of heterogeneous school communities13.
Continuity matters: to the extent possible, do not require students to change schools14. Opportunities matter: consider lease/purchase of strategic properties
THE ENROLLMENT PROJECTIONSThis year, the District retained the services of DecisionInsite to do the projections. This firmservices over 60 school districts, most of which are located in California. The firms services arehighly computerized and automated. District staff began using their mapping software last year.However, they offer a wide range of school district planning tools, including boundary changeanalysis, residential development research, community mailing lists, demographic reports and ofcourse, enrollment projections. Because of the degree of automation, there is an abundance ofinformation available and available quickly.
Staff was quite focused in their needs for the report for this year. We were interested in theenrollment projection, over multiple years K-12, as in the past. However, because of the Districtsmany conversations over the past on planning for additional elementary classrooms, we requiredstudent resident projections at least by elementary cluster, and better by individual elementaryschool attendance area. (Note: These are projections of numbers of students living in theattendance area of each school, not projections of the numbers of students attending each school.)As it turns out, the DI projections are based on an analysis by study blocks and since a studyblock can be a school, this works quite well for our purposes. Since they project K-12, we alsohave projections of student residents for each of the middle and high school attendance areas.
PREDICTING FUTURE ENROLLMENTLast years demographer, Lapkoff and Gobalet (L&G), made projections consisting of three levels:Low, Medium and High. Table 1 tracks the performance of the projections for the past four years,in terms of predicting next year of enrollment. From this table, the best predictor of next yearsenrollment is the High projection for elementary enrollment and the Low projection for both middleschool and high school enrollment.
DecisionInsite (DI) projections consist of two levels, Conservative and Moderate. We matchedyear-old growth projections of L&G versus the current projections of DI for both next year (2012)and five years from now (2016). Tables 2a-c and Tables 3a-c show the result of those matches. Inthe end, the DI Conservative projections tend to fall between the Low and Medium L&Gprojections. The DI Moderate projections tend to fall between the Medium and High L&Gprojections in the short term and are higher than the L&G High Projections for the longer term. Ourplan for now is therefore to use the DI Conservative projections when thinking about middle andhigh schools (perhaps with elevating the high school projection somewhat for next year), and usethe Moderate projections when thinking about elementary schools.
It should be noted that for both demographers, enrollment growth tends to level off after about thefirst five years. This is logical because they are analyzing existing development plans and knownprojects.

NOTES REGARDING THE ATTACHED TABLESThe tables have been constructed using DI data. The projected (or actual) growth numbers and
percentage growth for each year from the prior year are shown on the table. The aggregate five-year growth is also shown.
Special Day Class (SDC) students are recorded separately, rather than being considered as beinglocated in a school attendance area. The rationale is that the SDC students do not necessarilyattend classes in their neighborhood schools. Regarding aggregate total enrollment forelementary, middle and high school students, a rough and easy rule of thumb would be to add 90students to the elementary total, 70 students to the middle school total and 90 students to the highschool total.
District-wide projected enrollment is greater than the total of the projected numbers of students in
each attendance area. In addition to SDC students being recorded separately, the students livingoutside the District (e.g. employee privilege students, VTP students) are not of course in theattendance area student totals.
THE TABLESTables 4 and Table 5 show the Conservative and Moderate projections district-wide. Regardingaggregate total enrollment for elementary, middle, and high school students, an easy rule of thumbwould be to add 90 students to the elementary total, 70 students to the middle school total and 90students to the high school total.
Table 6 and Table 7 show the Conservative and Moderate projections by elementary cluster.There was great interest regarding the substantial change in the cluster growth projectionsbetween a 2009 projection and a 2011 projection. We now have another projection and one that isvery different from each of the earlier projections. It projects an enrollment decline in the northcluster, an increase in the south cluster and an even greater increase in west cluster.
Table 8 and Table 9 show the Conservative and Moderate projections by elementary schoolattendance area. These are the components that make up the cluster projections.
Table 10 and Table 11 show the Conservative and Moderate projections by middle schoolattendance area.
Table 12 and Table 13 show the Conservative and Moderate projections by high school attendancearea.
Attached to this document, you will find the DecisionInsite Analysis of Enrollment Projections reportprepared for the District and also a draft of a powerpoint presentation to be presented at thismeeting.

NEXT STEPSWe are taking a step that has not been done in the past years. Our first priority enrollment periodhas started and ends on February 10. A substantial amount of enrollmentespeciallyKindergarten enrollmenttakes place at this time. We will compare this years data to last year. Itwill give us another data point for projecting next falls enrollment by level, cluster and school.
Our calendar calls for a discussion in February about available capital funds. This item will beplaced on a Board meeting in February, in conformance with the timeline. We will also includesome initial discussion about elementary and middle school growth. We have also started staffdiscussions regarding recommendations for increased school capacity. We will be bringing this toa Board meeting in April, as called for on the timeline.
RECOMMENDATIONThe purpose of this item is to provide information and to seek comments and direction from theBoard of Education. No action is required.

Both a Moderate and a Conservative projection have been generated for the district. Conservative projections are
more suitable for staffing purposes; the Moderate projections more suitable for facilities planning purposes.
In general, Kindergarten enrollment over the past three years has been somewhat erratic. The data also show that
Cohort Patterns
the difference between the graduating cohort and the incoming cohort has been increasing.
Note that both studies project a slight increase at the Kindergarten level in the ten year future.
A typical student cohort ages from grade to grade relatively unchanged from the previous year. Historically, 3 cohortsshow more than a 5% annual change.
New Housing Development
District-wide Enrollment Projection
Over the period of years during which these units will be occupied, the annual impact in any given year, based on the
Moderate Study, is estimated in peak years to be 120 students.
Both projections forecast a significant increase across the 10 year period based upon the historical enrollment trends
Approximately 800 new residential units are projected to be occupied over the next 10 years.

Kindergarten ImpactKindergarten enrollment is often the most significant driver of overall future district-wide enrollment. A trend at
Kindergarten from year to year, or a trend in the difference between the district's graduating cohort in a given year and
the Kindergarten cohort the subsequent year, will eventually be reflected in the total district enrollment count.

Cohort ImpactA typical student cohort ages from grade to grade relatively unchanged from the previous year. By contrast, the cohort
matriculating from Kindergarten to Grade 1 is a common example of a cohort increase, typically attributable to
students returning from a private school Kindergarten.

Incoming Out-of-District Transfer Impact
Key Variables in Projecting District Enrollment
The number of students served from outside the district boundaries can impact enrollment. It is a factor over which the
district may have some control. For the past two years, the number of out-of-district students served annually has
been approximately 750, and has been relatively stable.
Both a Moderate and a Conservative projection have been generated for the district. The Conservative projections are
more suitable for staffing purposes; the Moderate projections more suitable for facilities planning purposes.
As a matter of standard practice, DecisionInsite does not typically include in the Enrollment Projections specialized
schools or programs such as Home and Hospital Programs, Community Day Schools or Independent Study
Programs. Our work is focused on projecting grade level enrollment for typical schools that are reported to the state.

Impact of Projected New Dwelling Units
Projected OccupancyApproximately 800 new residential units are projected to be occupied over the next 10 years. The tables below show
the mix of proposed units across the three dwelling unit types. The Moderate table summarizes the plans described by
developers. The most recent residential research was completed in November 2011 by Dr. Jacquie Schriber. The
Conservative table estimates a more likely scenario based on anticipated market conditions.

Projecting School Enrollment
School Draw Impact
School projections are primarily a function of the proportion of district students who enroll at a given school, modified
by intra-district transfers within a given school level that may occur subsequent to initial enrollment, and augmented by
inter-district transfer students.
A draw rate is the percentage of students who enroll at a particular grade level in a given school from a specified
geographic area. Open enrollment among district schools is projected using this concept. Except for changes in
Intra-district Transfers
,
(including out-of-district students) are assumed in the projections.
Transfers within the district are incorporated into the projections in order to anticipate the movement of students from
one district school to another within the same level, e.g., transfer from a neighborhood school to a special school.
Recent historical transfer patterns are typically assumed in the projections.
-
Transfers into the district by out-of-district students, sometimes referred to as permit students, are an integral part of
the district and school projections. Recent historical transfer patterns are typically assumed in the projections.

Enrollment projections are limited to typical K12 students. SDC students are projected as a stable percentage of the
typical population unless all SDC students are mainstreamed. Excluded from the projections are students enrolled in
Pre-Kindergarten, Adult High School, Home School, Adult Ed, Independent Study programs and other special
schools.
Attendance Boundaries
Closed SchoolsOpportunities for open enrollment (intra-district) are assumed to remain unchanged, unless otherwise noted by the
district.
Attendance boundaries are assumed to remain constant, unless otherwise noted by the district.

Inter-district Enrollment
Cohort Percent Change
Students enrolled from other school districts are treated in aggregate in separate studyblocks. Students in
Kindergarten, grade 1, and the initial grade at each level, are projected only to the extent they exist in recent years.
Students enrolled in other grade level cohorts are aged through to the highest grade at each level. These defaults
may be modified at district request.
Cohort percentage changes are calculated in order to assure sensitivity to perennial changes in students served by
the district as they age from one grade level to the next. If every cohort were stable as it ages, the cohort percent
change, from one grade to the next in each studyblock, would be calculated as 100%. For each studyblock, a cohortweighted average percent change over a defined number of years is calculated based on the change in the
enrollment served as it ages from the previous grade level.
Average cohort percentages above 100% might, for example, reflect students returning from private schools. Cohort
percentages below 100% might reflect drop-outs.

The predicted impact of new dwelling units on school enrollment is based on three factors: 1) new dwelling units, 2)
the student generation rate for each unit type, and 3) the grade level distribution of newly generated students.
default cohort percent change rate is set to 100% so as not to over-project new residential growth. By default, growth
is not predicted to continue unless new occupied dwelling units are projected.
.
2. Student GenerationStudent generation rates are determined for each product type for each level: elementary, middle school and
high school. Student generation rates are based on similar products types where such exist; otherwise, a
default generation rate is used.
New dwelling units are categorized into 3 housing types: Single Family Detached, Single Family Attached, and
Multifamily. Developers and builders are contacted for information relative to their plans for occupancy of new
dwelling units.
3. Grade Level DistributionFor each level, students generated by new dwelling units are distributed across grade levels. These
percentages are based on historical patterns where they exist; otherwise, default percentages are used.

Caveats on Projections and Methodology
On Projections
Enrollment projections are based upon two critical factors: the student and school data from the school district and the
mathematical formulas that are applied to those data. Projections fundamentally look at recent history as reflected in
DecisionInsite takes great care in preparing a districts projections. A range of unpredicted anomalies, however, can
cause reality to vary from the historical patterns. These include, but are not limited to, rapid changes in the economy,
mortgage interest rates, the housing market, the job market, residential development plans, rental rates, etc.
Anomalous changes that occur between the last set of student data and the first projection are not reflected in the
projections unless the district works with DecisionInsite to amend the projections.

reading. This rounding sometimes results in the displayed whole numbers in a column not adding exactly to the
displayed total of the column. This phenomenon, which is a result of rounding and not of any inaccuracy in the
calculations, occurs both in the enrollment projections and in the community demographics.
DecisionInsite obtains historical student data fi les from the district. To the extent that the student data files areinternally inconsistent from year to year, or the count of students in the fi les does not reflect the count of actual
enrollees, errors are introduced to the projection calculations. For optimum results, the student data files must also
consistently capture the same categories of students annually.

of each school year. It is important that the student files obtained from the district are close to a common date each
year, typically near the beginning of the school year. The snapshot of historical data near the beginning of the school
year is best suited to our goal of projecting enrollment for the beginning of subsequent school years. To the extent the
historical student data provided is not at one year intervals, or is not at a common date near the beginning of the
school year, projections may reflect monthly fluctuations in enrollment that will diminish the accuracy of the
pro ections.

General Conclusions
Community population relatively stable
Erratic Kindergarten history creates wider thanusual difference between the out year projections inthe two studies.
Some, but relatively minor impact from newhousing.
Out of district enrollment is stable.
Projected annual enrollment change is similar topast history: ~2-3%
