The National Report Card is a critique of state school funding systems and the extent to which these systems ensure equality of educational opportunity for all children, regardless of background, family income, place of residence or school. The report makes the assumption that "fair" school funding is defined as "a state finance system that ensures equal educational opportunity by providing a sufficient level of funding distributed to districts within the state to account for additional needs generated by student poverty."
Baker, B. D., Sciarra, D. G., & Farrie, D. (2010). Is School Funding Fair? A National Report Card. Education Law Center.
The Second Edition of the National Report Card on public school funding, Is School Funding Fair?, shows that far too many states continue to deny public schools the essential resources they need to meet the needs of the nation's 53 million students and to boost academic achievement. The National Report Card rates the 50 states on the basis of four "fairness indicators" - funding level, funding distribution, state fiscal effort, and public school coverage. The Report provides the most in-depth analysis to date of state education finance systems and school funding fairness across the nation.

The 3rd Edition of Is School Funding Fair? A National Report Card details how the Great Recession and its aftermath have affected school funding in the states. The National Report Card (NRC) examines each state's level of commitment to equal educational opportunity, regardless of a student's background, family income, or where she or he attends school. Providing fair school funding -- at a sufficient level with additional funds to meet needs generated by poverty -- is crucial if all students are to be afforded the opportunity to learn and be successful.

Using information on teaching spells in North Carolina, the authors examine the potential for using salary differentials to overcome this pattern. They conclude that salary differentials are a far less effective tool for retaining teachers with strong pre‐service qualifications than for retaining other teachers in schools with high proportions of minority students.

Although many factors combine to make a successful school, most people agree that quality teachers and school principals are among the most important requirements for success, especially when success is defined by the ability of the school to raise the achievement of its students.

The Principal Follow-up Survey (PFS), first conducted in school year 2008-09, is a component of the 2011-12 Schools and Staffing Survey (SASS). The 2012-13 PFS was administered in order to provide attrition rates for principals in K-12 public and private schools. The goal was to assess how many principals in the 2011-12 school year still worked as a principal in the same school in the 2012-13 school year, how many had moved to become a principal in another school, and how many had left the principalship.

Because principal turnover may occur in response to or contemporaneous with a downturn in student achievement, the effect of a turnover is confounded with unobserved school-level factors. We employ a novel identification strategy that blocks each potential source of endogeneity to isolate plausibly causal effects of within- and between-year principal turnover.

They find that schools serving many low-income, non-White, and low-achieving students have principals who have less experience and less education and who attended less selective colleges. This distribution of principals is partially driven by the initial match of first-time principals to schools, and it is exacerbated by systematic attrition and transfer away from these schools.

Prior research on teacher turnover focused mostly on whether or not and who leaves. This research builds on and extends prior studies by investigating not only whether and who but also when a teacher leaves. The phenomenon of this study emphasizes the dynamic nature of teacher exit.

Over the past twenty years there has been a decline in the number of minority teachers entering and remaining in the teaching profession. While the overall teacher shortage is worrisome for educators and administrators, the shortage of minority teachers is one of grave concern. A lack of minority educators inside our buildings is just one consequence of minority teacher shortage.

Recent media reports of teacher shortages across the country are confirmed by the analysis of several national datasets reported in this brief. Shortages are particularly severe in special education, mathematics, science, and bilingual/English learner education, and in locations with lower wages and poorer working conditions. Shortages are projected to grow based on declines in teacher education enrollments, coupled with student enrollment growth, efforts to reduce pupil-teacher ratios, and ongoing high attrition rates.
