Lead is a neurotoxin that has been shown to have a long and lasting impact on the brains, bodies, and behaviors of those who are poisoned. It also has a greater presence in communities with high levels of poverty and minority populations. Compounded over time, the effects of lead poisoning, even at low levels of exposure, impact a child's readiness and ability to learn. To investigate the relationship between the risk of lead poisoning, school level academic achievement, and community demographics, three sets of data were combined. The Lead Poisoning Risk Index (LPRI), used to quantify the risk in each census tract of being poisoned by lead, standardized state assessment data for third grade reading and eighth grade math, and census 2000 demographic data were combined to provide information for all Arizona schools and census tracts. When achievement was analyzed at the school level using descriptive, bivariate correlation, and multivariate regression analyses, lead's impact practically disappeared, exposing the powerful effect of poverty and race on achievement. At a school in Arizona, the higher the percentage of students who are poor or Hispanic, African American or Native American, these analyses' predictive models suggest there will be a greater percentage of students who fail the third grade AIMS reading and eighth grade AIMS math tests. If better achievement results are to be realized, work must be done to mitigate the effects of poverty on the lives of students. In order to improve schools, there needs to be an accounting for the context within which schools operate and a focus on improving the neighborhoods and the quality of life for the families of students.

The term "White flight" and its effects are well documented in large urban city centers. However, few studies consider the same effects on smaller American communities. This case study investigates Lexington, Nebraska, a rural community of approximately 10,000 citizens, that has experienced a population influx of minorities in the last 25 years. The population shift has increased the representation of Hispanic, Asian, and now Somali students in the Lexington Public School system, which, in turn, has been accompanied by a dramatic decrease in White, Anglo students. This study attempts to identify and describe the reasons for the exodus of White students from the public school setting. Possible reasons that might explain the decreases in White student enrollment may include overcrowding in schools, unsafe school environments, and/or less one-on-one attention with classroom teachers.

This study was designed to capture the conversations and practices of seven educators who navigate teaching and learning decisions in their Title 1 elementary school. This case study was conducted to answer the research question, "What are the behaviors and practices of a newly formed collaborative team of educators working within a professional learning community (PLC)?" In order to understand how this collaborative team worked together, data was collected through a survey, interviews, focus group discussion and questionnaire, observations of collaborative team meetings and artifacts generated from the team's work. The findings revealed that (1) participants spent the majority of their collaborative team time focusing on how to best prepare students for district and state standardized assessments; (2) teachers described themselves as learners who look to their colleagues to enhance their knowledge and skills; (3) members of PLCs need dedicated collaborative time to ensure all students and adults in the organization learn at high levels; (4) discussing and using student learning data can be difficult; (5) educators gravitate to colleagues who have similar philosophies and beliefs and (6) PLCs need supportive district, school and teacher leadership to accomplish their goals. This research study provides validation that the PLC process is a complex process of professional development designed to support school reform in an era of increased school accountability. The recommendations for school leaders are to create supportive leadership structures that allow all students opportunities to learn, build trusting environments, and provide clarity and focus of the vision for all stakeholders. District leadership needs to establish a priority for PLC work by embedding the processes in the vision, mission and goals of the district, examine policies to ensure they support the concepts of PLCs, provide access to resources and create a forum for critical conversations about teaching and learning. Policy makers need to ask the right questions so that they can design appropriate accountability systems that encourage collaboration.

This study examined the quality of professional life at a Title I school that has achieved the Arizona Department of Education's highest accountability rating of Excelling for eight consecutive years. By examining the factors that influence the school environment including teachers' attitudes and the connections within the teacher community at this school, a description emerged of the factors that influenced the quality of professional lives of teachers. This descriptive study sought to describe, "What is the quality of professional life for teachers at a Title I elementary school with a history of high levels of student achievement?" The research was conducted at Seneca Elementary school (a pseudonym) in the Seneca School District (a pseudonym). By examining the quality of professional life for teachers in a highly ranked Title I school, a better understanding of the quality of professional life may lead to recommendations for other schools with high levels of poverty on how to support teachers who work in high poverty schools. Within a theoretical framework of motivation-hygiene theory and socio cultural theory, the study identified principal leadership as a primary supporting factor of quality of professional life. The study also identified lack of input and lack of teacher control over curriculum and instruction as barriers to quality of professional life. Teachers described principal leadership, environment, social factors and teacher identity as contributors to enhancing the quality of professional life. Trust and focus emerged as additional factors that improved the workplace for teachers.

The purpose of this study was to explore features of Supplemental Educational Services (SES) implementation at the district level. In the study beliefs, goals, and actions of district office administrators were analyzed against the backdrop of changing federal guidelines and challenges faced by SES implementers across Arizona. The case study focuses on implementation in the 2007-2008, 2008-2009, and 2009-2010 school years. The study uses the 2005 and 2009 Department of Education guidelines, survey responses from Arizona district and school implementers, as well as documents and interviews from an urban Arizona case district. The study separates the implementation activities into task areas, which are analyzed separately. Using a loose coupling perspective, the separate task areas are furthered used as coupling domains and represented in social network graphs. Results show that the case district personnel were highly focused on their primary role, maintaining district compliance with federal guidelines. The district personnel employed several changes over the case study period to centralize their control of SES operations within district. The employment and training of site level coordinators was the most impactful of the strategies. As boundary spanners, the coordinators allowed greater access to information, oversight, and influence at the site level. Despite the growing capacity and earnest efforts of the district personnel, the case district was still very far from being able to measure or assess the impact of SES on student achievement. Centralization in the scholastic task areas was relatively low, and had marginal changes over the case study period. Years into the program, there was still no avenue to accurately gauge the effectiveness. As the district personnel were chiefly concerned with compliance, they had suspended judgment on the program and focused primarily on improving their processes.
