The purpose to this study was to provide a comprehensive analysis of per pupil expenditures at a specific school site. The objectives were threefold. The first objective was to determine per pupil expenditures, the second question was to determine variations in expenditures on a per student basis and finally, the third question in the study was to explain the factors that contribute to any identified variation in expenditure patterns. The sample consisted of one urban elementary school in a mid size district on a traditional school calendar. The population consisted of 611 students in grades K-5. This particular school and district participate in the California class size reduction plan for grades K-3. The school is located in a low socioeconomic area and is designated a schoolwide Title I program. This particular school is considered to be a high performing school and has been honored as both a Title I Achieving school and as a California Distinguished School in recent years. This study analyzed the expenditures at the end of the 2006-2007 fiscal year and assigned these expenditures to individual students using three major categories: direct costs to the classroom, direct costs to individual students and overhead costs. Direct expenditures to the classroom consisted of the cost of teacher salaries, paraprofessional salaries and benefit costs. Direct expenditures to students were calculated using information obtained regarding individual student participation in intervention or enrichment programs. Overhead expenditures included administrative costs, instructional support costs, clerical support, custodial, maintenance costs and ground's upkeep. Once the expenditures for all students were obtained, these data were analyzed by category. Factors such as grade level, ethnicity, gender and language classification were considered in order to determine variation as well as the reason for these variations. The major variations in expenditure per student were related to class size and special program participation in either enrichment or intervention programs. It was determined that teacher salary also played a role in expenditure variation. [The dissertation citations contained here are published with the permission of ProQuest LLC.
