This article is the third of four articles in the PE Metrics series related to the value of using national assessments to inform teachers, students, parents, and administrators about student progress at the elementary level toward achieving the National Standards for Physical Education (NASPE, 2004) for Standard 1. The first article focused on the importance of assessing student learning. The second explained formative and summative assessment processes and instructional considerations when implementing the standards. This third article discusses the benefits and advantages of using the assessments that appear in "PE Metrics: Assessing the National Standards, Standard 1: Elementary" (NASPE, 2008). These benefits and advantages of implementing nationally tested assessments will provide teachers, students, parents, and administrators with valuable information on student learning.
