Education Reform / NCLB

Eighteen education policy experts put the past decade's surge in high-school reform efforts to the test in Saving America's High Schools from the Urban Institute Press. Led by coeditors Becky Smerdon and Kathryn Borman, the team of authors size up national reform trends and draw on at least five years of research in Baltimore, New York City, Chicago, Ohio, and North Carolina.

Our educational system is in a continuous state of reform, yet outcomes are nowhere near what we can accept. Though the search for answers is perpetual, many efforts over the past decade have homed in on one feature of high schools—their size. If we simply reduce school size, the argument goes, students will gain a safer environment that can address their individual needs. It seems like common sense, but such changes alone have not proven a magic bullet. Saving America's High Schools offers quantitative research drawn from large-scale reform studies along with recommendations for federal, state, and district reform.

Using a ten-year student-level panel dataset from North Carolina, we examine how school-specific pressure related to two school accountability approaches (status and growth) affects student achievement at different points in the prior-year achievement distribution. We find little or no evidence that schools in North Carolina ignore students far below proficiency under either approach. Importantly, we find that the status, but not the growth, approach reduces the reading achievement of higher performing students, with the losses in aggregate exceeding gains at the bottom. The distributional effects of accountability pressure depend on the type of accountability pressure and on the tested subject.

This paper brings to bear new evidence from a remarkable five-year survey conducted of a census of public schools in Florida, coupled with detailed administrative data on student performance. We show that schools facing accountability pressure changed their instructional practices in meaningful ways. In addition, we present medium-run evidence of the effects of school accountability on student test scores, and find that a significant portion of these test score gains can likely be attributed to the changes in school policies and practices that we uncover in our surveys.

This brief describes estimation and measurement issues relevant to estimating the quality of instruction in the context of a cumulative model of learning. It also discusses implications for the use of value-added estimates in personnel and compensation matters. The discussion highlights the importance of accounting for student differences and the advantages of focusing on student achievement gains as opposed to differences in test scores. Despite potential shortcomings, value-added analysis can provide valuable information for use in evaluating and compensating teachers. The key is not to be cavalier about the information contained in value-added estimates but to understand the pieces that go into producing estimates of teacher quality.
