Success in the Middle Act of 2007 - Directs the Secretary of Education to make matching grants to states, based on their proportion of poor children aged 5 to 17, to: (1) implement state middle school needs analyses and, on the basis of such analyses, improvement plans that describe what students must master to successfully complete the middle grades and succeed in academically rigorous high school coursework; and (2) award competitive matching subgrants to local educational agencies (LEAs) to implement a comprehensive middle school improvement plan for each eligible school. Favors LEAs with high proportions of poor children and eligible schools.
Defines "eligible schools" as those where: (1) a majority of middle grade students matriculate to high schools with graduation rates below 60%; (2) more than 25% of the students who finish grade six, or the school's earliest middle grade level, exhibit key risk factors for failure; and (3) a majority of middle grade students are not rated proficient on required state assessments in mathematics, reading, or language arts.
Permits states to make subgrants to LEAs that did not receive a competitive subgrant to assist them in applying for competitive subgrants and developing comprehensive middle school improvement plans.
Provides the Secretary with funding to: (1) contract for studies that identify promising practices for, and review existing research to identify factors that might lead to, the improvement of middle school education; (2) create a national clearinghouse in best middle grade educational practices and a national database identifying factors that facilitate or impede middle grade student achievement; (3) require certain educational field research designed to enhance the performance of middle grade schools and students; (4) create a research and development center that addresses topics pertinent to middle grade schools; and (5) provide grants to entities that partner with states and LEAs to develop, adapt, or replicate effective models for turning around low-performing middle grade schools.
