SUMMARY
Applied Data Services (ADS) calculated enrollment projections based on both a 5-year enrollment history and a 3-year enrollment history. A comparison of the resulting K-12 projections, through 2017/18, for each of the two sets shows a minimal difference of 41 students in 2017/18. Applied Data Services is recommending the use of the last five years of enrollment history to best predict enrollments for the next five years. The historical enrollment for grades K-12 decreases 7% while enrollment for grades 6-8 remains constant from 2007/08 through 2012/13. The grade 9-12 enrollments increase 8%, 256 students, over the past five years. The K-5 enrollments decreased each year, from 4,614 in 2007/08 to 3,638 in 2012/13, a decline of 21%. All of the elementary schools have declined over the past five years. The projected enrollment for grades K-12 decreases from 9,437 students in 2012/13 to 7,647 students in 2017/18, resulting in a loss of 1,790 students over 5 years. This decrease represents a 19% enrollment decline over the next five years. The decrease in projected enrollments through 2017/18 is based on the large number of students leaving the school system that represented the last of the ‘enrollment explosion’ which peaked in 2006/07. These outgoing students are being replaced at the elementary level by fewer kindergarten students resulting from declining births. As shown on Table 1a, the projected enrollments of all of the seven elementary schools decline from 2012/13 through 2017/18 Candlewood Middle School loses 248 students from 2012/13 to 2017/18, a decline of 29% while West Hollow Middle School decreases approximately 21% over the same period. The projected enrollments at Half Hollow Hills HS East and West, decrease 7% and 14%, respectively, over the next five years. The survival ratios for the K-12 grade pairs (except grade pair 8,9) exceed 100%, indicating growth and can probably be attributed to a resale of homes from empty nesters to families of childbearing age, and/or a withdrawal of private and parochial students from all grades with entry into the public schools as a result of the cost of tuition and the current economic climate. The birth to kindergarten ratio of 1.239 indicates 24% more children enroll in kindergarten than are born in the district (5 years earlier).

INTRODUCTION
A demographic/redistricting study was awarded to and prepared by Applied Data Services (ADS) for the Half Hollow Hills Central School District to provide enrollment projections in order to plan for the efficient use of facilities for the next five years. Applied Data Services would like to acknowledge the offices that provided pertinent data for this report, in particular State of New York Health Department, the Transportation Supervisor, and the Suffolk County Planning Board, as well as the district’s Administration for their assistance and timely provision of the data necessary to conduct this study. Background Half Hollow Hills Central School District is located in western Suffolk County, Long Island New York. The district is part of both the Huntington and Babylon Townships. The school district contains eleven schools (seven elementary schools, two middle schools, and two high schools). The school district serves approximately 9,500 students and a staff of approximately 850, including 750 teachers. Half Hollow Hills Central SD is committed to providing optimal learning conditions that: set the highest expectations for all students, teachers, and the community; are motivating, fully engaging, orderly and safe; engage all students, teachers, and community members in an active committed effort to help each student, teacher, and community member to use his or her intellectual, social, and physical capacities to achieve personal goals in ways that foster the success of the society.

Report Contents The current school year 2012/13 is the base year for the projected enrollments. The current enrollments by school, by grade (on or about October 1, 2012) were provided by Central Administration. These statistics are included herein, as the last set of reports entitled “Historic / Projected Enrollments by Building by Year by Grade.” There are eleven schools included in this report with a grade range from Kindergarten through grade 12. Data Collection The enrollment data for each of the past five years was provided by Central Administration and reported by school by grade – identifying both regular and special education enrollments (on or about October 1), as well as the Student Enrollment Summary Report identifying all students (including self-contained special education) by school, by grade, by ethnicity. For the purposes of enrollment projection the regular and special education historical enrollments were combined for each grade. Both the historical and projected enrollments in this report include the special education students. For this study two sets of projections were performed. The survival ratios were calculated using a 5-year enrollment history and a 3-year enrollment history. A comparison of the resulting K-12 projections through 2017/18, for each of the two sets, is presented in Figure 1. Selecting a 5-year enrollment history is an expectation that the enrollments will grow or decline on the same average basis as the last five years. Based on the economic climate and slight growth, Applied Data Services is recommending the use of the last five years of enrollment history to best predict the next five years. The history of births, necessary for projecting the Kindergarten enrollment through 2017/18, was obtained from the New York State Department of Health. These were reported by school district area i.e. specifically Half Hollow Hills. Prepared by Applied Data Services For Half Hollow Hills CSD

DESCRIPTION OF THE PROCESS
Introduction Effective planning requires schools to forecast long-term enrollment projections on a district and school basis. While short-term (one year) projections are accomplished with a high degree of confidence, five year projections can be more uncertain. It is generally recognized by demographers that component and cohort survival methods are most adequate in reducing the relative error in projections. Projections based upon children already in the district (the current K-8 population only) will be the most reliable. The second level of reliability will be for those children already born into the community but not yet old enough to be in school (live births). The least reliable category is the group for which an estimate must be made to predict the number of births, thereby adding an additional variable of uncertainty. This occurs when 10 year enrollment projections are performed. Other factors contributing to this uncertainty include: A parochial school closed or other students returned from non-public schools. A charter school opened. The kindergarten program changed entrance age or to an extended/full-day program. The high school toughened its course credit/graduation requirements. The district set new attendance boundaries for elementary schools. Annual updates to the projections allow for early identification of recent changes in historical trends. When the actual enrollment in a grade is significantly different (high or low) from the projected number, it is important to determine whether this is a one-year aberration or whether a new trend may be starting. It is thereby recommended that all school districts have updated enrollment forecasts performed at least every other year. Description of Projection Techniques The ADS proprietary Enrollment Projection System (EPS) uses the five (or three) year component cohort survival method (which is used by most local, state and federal agencies) for making five year projections of district and school enrollments. This method calculates an average survival ratio (persistence factor) from one grade to the next. The survival ratio expresses a quantitative relationship between the numerical size of a group (grade) in a given year in comparison to the size of the same group in the previous year. The number of students in a group in the present year is divided by the number in the group the previous year. If the quotient is greater than 1.0, the size of the group has increased; conversely, if the quotient is less than 1.0, the size of the group has decreased. If a survival ratio is l.000, there has been no change in the class size as the students move from one grade to the next. For example, if a school district had 1000 sixth graders last year and 789 seventh graders this year, the district sixth-seventh grade survival ratio is .789 i.e. only 79% of the students survived from grade six to seven.

In part, the survival ratio is also important as an index of the degree of "holding power" of a district. In most suburban school districts, its magnitude is influenced by factors, such as sizable amounts of affordable housing, large birth rates, turnover in the so-called "second generation" housing resale market, available rentals, and an increasing number of adults in the childbearing age category. Under some circumstances, survival ratios may be partly affected also by prevailing perceptions held by residents of a community concerning the "quality" of a given school district, or of a particular school within a district. Nevertheless, whatever the source of variation in these ratios from year to year, the average ratios reflect, numerically, the net result of all influences (available housing, births, economy, etc.) on the in- or outmovements of students, by grade, over a five-year period. The enrollment projections performed by ADS, are based primarily on the use of a five-year average for computing survival ratio (SR) for each grade pair. The SR for each grade was multiplied by the enrollment of the previous grade in the previous school year, to obtain the future enrollment for each grade. EPS also provides the capability to evaluate enrollments versus building capacities, assess the effect of grade reorganization or other redistricting needs, evaluate enrollment distributions as a result of school closings, assess the impact of changes in school feeder patterns and evaluate the effects of modifying school attendance boundaries.

Comments on Projected Enrollments
The projected enrollment for grades K-12 decreases from 9,437 students in 2012/13 to 7,647 students in 2017/18, resulting in a loss of 1,790 students over 5 years. This decrease represents a 19% enrollment decline over the next five years. The decrease in projected enrollments through 2017/18 is based on the large number of students leaving the school system that represented the last of the ‘enrollment explosion’ which peaked in 2006/07. These outgoing students are being replaced at the elementary level by fewer kindergarten students resulting from declining births. As shown on Table 4b, the projected enrollments of all of the seven elementary schools decline from 2012/13 through 2017/18. Candlewood Middle School loses 248 students from 2012/13 to 2017/18, a decline of 29% while West Hollow Middle School decreases approximately 21% over the same period. The projected enrollments at Half Hollow Hills HS East and West, decrease 7% and 14%, respectively, over the next five years. Effect of the Academically High Achievement Program (AHAP) The Academically High Achievement Program, or AHAP, currently offered by the Half Hollow Hills CSD does not affect the projected enrollment in any of the schools.

Survival Ratios
The survival ratios were computed based on a five-year history for each grade. The survival ratios for each grade pair were then applied to each grade in each of the schools to calculate the projected enrollments. The projected enrollments by grade, by year are obtained by adding each of the grades for the schools. The survival ratios are presented below for each grade pair through years 2012/13 and 2017/18.

Analysis of Enrollment Trends The survival ratios for the K-12 grade pairs (except grade pair 8,9) exceed 100%, indicate growth and can probably be attributed to a resale of homes from empty nesters to families of childbearing age, and/or a withdrawal of private and parochial students from all grades with entry into the public schools as a result of the cost of tuition and the current economic climate. The birth to kindergarten ratio of 1.239 indicates 24% more children enroll in kindergarten than are born in the district (5 years earlier). This also supports the turnover of homes over the past five years to families with children of elementary and pre-school age. 4.
Assigning Projected Kindergarten Students to Their Elementary Schools
The total number of Kindergarten students are projected on a district-wide basis and distributed to each of the elementary schools on a percentage basis. The percentage is calculated using the number of first grade in each elementary school relative to the total number of first graders in the district. 5.
Special Education
In this section the grade K-12 projected enrollments of special education students by school are illustrated for each year through 2017/18. A building by building approach was used to project the special education students. The historical special education enrollment by building was compiled for the last four years and is presented below in Table 5a. Although a building by building approach was used, these projected students can be reassigned to other locations. The percentage of special education enrollment is calculated for each of the past four years. These percentages are then averaged and the average applied to each of the buildings’ projected enrollments to determine the number of special education students for each year through 2017/18 (see Table 5b). This average percentage for each building is shown on Table 5b as SCSE %. Historically the self-contained special education enrollment remained relatively constant from 2009/10 through 2012/13, averaging 417 students per year, approximately 4.3% of the total districtwide enrollment.

New Construction
As described, the cohort survival projection methodology employs an “averaging” technique. Past enrollments are averaged by grade to calculate the survival ratio for each grade pair. These past enrollments take into account new construction, in-migration and out-migration occurring from housing turnovers, mortality, new business, etc. New construction is reflected by the number of Building Permits. This construction includes single family dwellings and one, two or three bedroom condominiums. The table below identifies the number of Building Permits issued for new residential housing units. Pertinent to this study are the permits listed in the ‘unincorporated’ areas for the towns of Huntington and Babylon as the Half Hollow Hills school district is comprised of these geographic areas.

Source: U.S. Census Bureau (Construction Statistics Division)
On the average over the past five years, 62 permits were issued for the unincorporated areas of the town of Huntington; with an average of 72 permits issued for the unincorporated areas of Babylon over the same period. The current number of permits issued is not significantly higher than the average to warrant an adjustment in the projected enrollments. However, there is an indication that the trend in building has ‘bottomed out’ in 2011, with an upturn occurring in 2012. This trend merits attention over the next several years.
