Measures of student growth offer a richer understanding of student performance than a moment-in-time test score alone, but measures of student growth are not created equal. In their accountability plans for implementing the Every Student Succeeds Act (ESSA), some states are using a sophisticated analysis of multiple data points that evaluate the…

While federal law requires students to be tested in math, English-language arts and science in particular grades, states are still struggling to mount the resources and expertise necessary to fully implement college and career readiness standards, let alone new assessments aligned to these higher standards. New assessments are not only more…

There is a widespread consensus among practitioners, researchers, and policy makers that current teacher evaluation systems in most school districts do little to help teachers improve or to support personnel decision making. For this reason, new approaches to teacher evaluation are being developed and tested. There is also a growing consensus that…

The nation is showing an unprecedented focus on increasing the rigor in education and preparing students for college. The college readiness trend is driving changes in the ways in which the nation uses student test data. Educational data are no longer limited to static data snapshots showing the status of a student performance at one point in…

The purpose of this Guide is to advise researchers, policymakers, and others on when it is possible to conduct a high-quality randomized controlled trial in education at reduced cost. Well-designed randomized controlled trials are recognized as the gold standard for evaluating the effectiveness of an intervention (i.e., program or practice) in…

Psychologist Andrea diSessa coined the term "phenomenological primitives", or p-prims, to talk about nonexperts' reasoning about physical situations. P-prims are primitive in the sense that they stand without significant explanatory substructure or explanation. Examples are "Heavy objects fall faster than light objects" and "Continuing force is…

Analyzing growth rates and percentiles of achievement are two ways that school systems can evaluate school performance. Boards should also consider parent-teacher satisfaction, internal management systems, school board evaluation, and a number of other indicators. (MLF)

In September 1991, the National Assessment Governing Board (NAGB) announced standards for basic, proficient, and advanced achievement in mathematics and reported that few American students had reached these standards. Expert reviewers noted technical problems with the NAGB approach and questioned its results. In this report, the NAGB…
